Troubleshooting for Car GPS Tracker Connection Problems

If you follow the instructions that come with the your software to connect your GPS Tracking Devices For People to a computer, usually getting the two devices talking is painless. If you do run into problems, follow this set of steps, in this order, to help you identify a possible culprit for your connection troubles:

1. Always make sure the cable is securely plugged in to both the GPS receiver and the computer. While you’re at it, check that the GPS receiver is turned on.

2. Make sure that the baud rate and the protocol are the same in both the GPS receiver and the interface program. Double-check this again if you can’t establish a connection. Even if the baud rates match, they may be set too high — thus causing communication errors. When in doubt, lower the baud rate. You can either step-down a rate at a time or go directly to 4,800 or 9,600 baud. Although this is slow, this rate shouldn’t generate errors.

3. In the interface program, make sure that the correct COM port is specified. If you can’t get a connection, try different COM port numbers until you find one that works.

4. Always check the program’s user manual, online help, or support section of the vendor’s Web site for specific information on interfacing with a GPS receiver. If you can’t get your GPS receiver to talk to your computer and you happen to have a PDA, turn off the PDA synchronization program first. PDA synchronization software that’s running in the background is a frequent culprit in causing GPS receiver interface problems.

Turn here directions: The GPS receiver lists all the streets and roads in your route at which you’ll need to make turns, including the street name, an arrow that points to the correct turning direction, how far ahead the turn is, and how long it’s going to take to arrive at the turn. The GPS receiver gives an audible or visual signal prior to when you need to turn. Points of interest: Maps that are used with road navigation GPS receivers have databases of information about gas stations, restaurants, freeway exits, hotels, attractions, entertainment, shopping, and emergenc services along your route. These are dubbed Points of Interest (POIs); the GPS Tracker For Car can display information about specific POIs. External antenna support: Because the metal body of a car or truck might interfere with satellite signals, an external antenna might be required to connect to the GPS receiver. An external antenna also provides you with more mounting location options because only the antenna needs to be mounted someplace with a clear view of the sky. Note: Some heated windshields can block satellite signals. In cases like that, you’ll probably need to use an external antenna with a magnetic roof mount.

If you’re a GPS road warrior, you’ll definitely want a 12-volt cigarette lighter adapter so you don’t go through a lot of batteries during a trip. And finally, if you’re more of an urbanite (versus an outdoors) adventurer, another option is to use a PDA, such as a Pocket PC or Palm with Motorcycle GPS Tracker and street navigation software. Chapter 6 discusses the ins and outs of using PDAs with GPS.

GPS device history: multienvironment GPS tracking devices and warrants

In the early twenty-first century, it was possible to see various land-based GPS transponders ‘ sold by companies such as Ness Technologies that had magnetic mounts and allowed first responder agencies to track ambulances in real time. When vehicles are tracked, better 55 dispatching of vehicles can be done in time of emergency. If one has emergency management exercises, vehicle tracking can be used as part of a performance gauge and to see if resources were used efficiently. By 2011, other companies had GPS tracking devices for Q any environment including air, land, or sea. These types of tracking devices can not only be used for resource allocation but also in criminal or corporate investigations.

An example of one of these new devices that is now available to the consumer, corporate investigator, private investigator, and law enforcement officer is the LandAirSea TracKing® Vehicle GPS Locator. This device has been sold from Radio Shack. This device can be used in the air, on the land, or on the water with a variety of vehicles. The device works in temperatures of —15°F to 185°F which is important since airplanes may encounter severe temperature changes in one trip. The device can be used to send out a beacon of its location every second. The receiver can then find out information on the device’s direction, speed, and location. The device uses two AA batteries and can function to durations of 80 h on one set of batteries.

This type of multienvironment device is ideal for investigations where a suspect may use a boat, plane, or car. The device could also be misused by a stalker who tracks an ex-lover and then an investigator may need to do an investigation about the stalker’s mis- use of the Electronic Tracking Device. The amount of uses, misuses, and types of investigations that may result are numerous. If a digital examiner has to examine a GPS navigation device for the airplane, there can be some error because the device is used at a high altitude. Flight location has to be exact since people fly at night, in bad weather, and use instruments when landing at night. There are multitudes of Federal Aviation Administration (FAA) documents online or inline that discuss the Wide Area Augmentation System (WAAS). The WAAS system works with known ground points and GPS satellites through a Ground Uplink System (GUS) and provides an error correction system for the navigation system of the aircraft. The WAAS system can provide as much as 7 m of accuracy to the navigation data of an airplane.

There exist Personal GPS Tracking Device that transmit a signal and allow someone with a corresponding receiver to obtain real-time location data for that tracking device that is difficult to see since and it can be just a small magnetic item that one sticks under the car. It is possible that the device may also have a small storage device that holds information on where a person drove and it could be examined later. The U.S. Supreme Court at syllabus U.S. v. ]ones decided on January 23, 2012: “The D. C. Circuit reversed, concluding that admission of the evidence obtained by warrantless use of the GPS device violated the Fourth Amendment” [9]. It seems that this may have future implication for collecting data on a variety of mobile GPS devices. It goes to show how the law can change and private investigators and law enforcement people have to keep up with the law.

Vehicle GPS Tracking Device for Motor Fleet Safety and Security Management

Usually, at best a GPS Tracker For Car incorporates GNSS in differential mode, which allows a user to calculate his or her position with an accuracy of about a meter or at most a few decimeters. This is enough for most of applications. However, many applications may benefit greatly from better accuracy. Among such applications are GIS, car navigation with automatic parking and driving, and collision avoidance. For pedestrian applications, DGPS, whilst good enough for most people, cannot accommodate applications, for example, for users with limited visual abilities.

The main question relating to the application of RTK positioning in mobile devices is whether it is possible to achieve on a cheap mobile handset platform. At the beginning of this chapter, we referred to a test that has demonstrated RTK positioning using a mobile front-end chipset and a module from different vendors. The front ends are intended for mobile devices, and their costs meet mobile device cost requirements. If for some types of mobile devices, or for some positioning modes, the antenna problem can be resolved and the code and phase observables are available, the system may run into the next problem: that there must be a reference station in the vicinity of the user. The distance from the reference station when using RTK positioning should generally be no more than 10 km on average, which is significantly different from code differential GPS, where distances to reference stations can exceed several hundred kilometers.

While in transit trucks can be an easy target for violence, and companies must train drivers to be aware of their personal security and, more important, prepared for the unexpected. Trucks are most vulnerable when they are stopped. Few trucks in the U.S. are equipped with truck security systems. Technology presently exists for ignition kill capabilities and for Global Positioning System ( Mini GPS Tracker ) tracking by fleet operators. These methods and developing technologies can play important roles over time in truck security. The trucking industry needs to develop standards to support the transition to these approaches as they become routine and available. Spot, routine, and high-risk truck inspections are infrequent. At truck stops, unattended vehicles are frequently left with their engines running, and these areas are usually unguarded.

These stops require the presence of security personnel and increased law enforcement surveillance at and around these areas. There are only a minimal number of secure parking areas available along America’s roadways, so drivers often use vacant unsecured areas as rest stops. Since September 11, 2001, the role of truck driver has become more important. Now more than ever, America depends on truck drivers to move freight safely and securely, especially if transporting hazardous materials. While high-valued commodities have always been hijacking targets, shipments capable of mass destruction or environmental damage must now be protected with the utmost care. Here are some safety tips and steps drivers should follow while traveling on the road alone with cargo, explosive, or hazardous materials. You may want to pass these along to your drivers:

Be alert when leaving. Criminal surveillance often begins at, or within a mile of, origin.

Do not discuss cargo, destination, or other trip specifics on open radio channels or near unfamiliar persons.

If you believe you are being followed, call 911 and your dispatcher immediately. Avoid being boxed in by other traveling or parked vehicles.

Where it is possible, leave room in front of and in back of your vehicle.

Look for vehicles following you, especially if there are three or more people in a vehicle.

If you believe you are being hijacked, try to keep your truck moving while keeping an eye out for enforcement officers.

How to protect Wireless IP Camera from dust and vandalism

Housings are used to protect vital Wireless Home Cameras equipment; consequently, the material used for their construction must be chosen carefully. Underwriters Laboratories (UL) has developed guidelines for minimum fire-safety requirements and suggested tests and ratings for fireproof or fire-retardant designs. This is especially important for non-metallic designs. The housing design must permit easy access and serviceability under these conditions. Manufacturers provide one of several means to gain access to the housing:

(1) removable top cover (2) hinged top cover (3) top cover or camera/lens on slide (4) removable front and/or rear cover (5) hinged bottom cover (dome) (6) top cover on slide.

When the dome housing is used for protection only and its pointing direction need not be concealed, the clear plastic dome is the best choice, since it produces only a small 10 or 15% light loss. If the camera’s pointing direction is to be concealed for additional security a coated or tinted dome is required. The aluminized dome is the earliest version of the coated dome and attenuates the light passing through it by approximately two f-stops (equivalent to approximately a 75% light reduction or loss). While this type of dome is still in use, the preferred dome material is a smoked plastic or tinted plastic that attenuates the light approximately one f-stop, or 50%. In contrast to rectangular housings using flat plastic or glass windows with excellent optical quality and transmission, some dome systems add slight optical distortion to the video picture. In high-quality domes the image distortion is almost negligible, but in some systems the distortion or loss in resolution is noticeable. The five housing types that account for most security installations are:

(1) rectangular (2) dome (3) wedge (4) triangular (5) wall- and ceiling-recessed and surface-mounted.

Under this condition, there is at least symmetry of distortion, that is, the primary effect is that of a weak lens producing a small change in the focal length of the total lensing system and is usually not noticeable. If the camera/lens pointing axis is not perpendicular to the dome surface and looks at an oblique angle through the dome housing material, noticeable distortion will occur; for example, images may appear elongated vertically or horizontally. If the dome and Wireless Security Cameras are in a fixed position with respect to one another, the distortion is generally less noticeable than if the lens is scanning or tilting while the dome remains still.

Wedge Housing

One version of the wedge housing is designed to replace an existing standard 2 feet × 2 feet drop ceiling tile and another version is designed for surface mounting.There are no additional accessories required. The design allows for manual pan adjustments of 360 and minor tilt adjustments. After final pointing the center camera/lens section is restricted from rotating by tightening thumbscrews. The camera’s wedge shape aims the camera about 15 down from the horizontal. The front of  the protrusion has a viewing window of clear acrylic with no distortion and virtually no light transmission loss. Another version is a small surface-mounted wedgeshaped housing that can be attached to any ceiling. These are available in either a surface- or recessed-mounting configuration. Some housings are designed to provide concealment and improved aesthetics by recessing them into the wall or ceiling. There are three different types of plastic dome materials through which the lens views the scene:

(1) clear (2) semitransparent aluminum- or chrome-coated (3) tinted or smoked plastic.

How to select best Rearview Mirror Camera for your car

Rear View Mirror Camera  technology is a fantastic safety feature in any car, so much so that by 2018 all new cars must be fitted with these units. From hooking up your trailer, reversing into a tight parking spot or just making sure your kid is not behind your car when you reverse, these units will make the job so easy. If you are in the market for a new rear view camera there are some pitfalls that will cause serious buyers remorse so this guide should make your decision much more informed and easier.

The biggest factor in choosing a rear view camera is how much can you see. So your biggest 5 factors are:

1. Automatic System Switching

Possibly the most important feature to look for when purchasing a rear view camera system, is that system's ability to switch on automatically whenever the vehicle's transmission is placed in reverse. This is accomplished by connecting a single wire to the vehicle's backup light circuit, sending a signal to the rear view camera system, causing it to switch on without any action by the operator.Many so-called ‘rear view camera systems‘ don't have this feature, and will require you to manually switch the system on every time you want to see behind you. The higher end systems will have this ability to switch on automatically, in addition to being turned on manually any time using the monitor's front panel power button (or wireless remote control, if so equipped). Since it's very inconvenient and extremely unsafe for the motor vehicle operator to be required to switch the system on manually every time he or she wants to back up, it's imperative that you never purchase a rear view camera system without the ability to switch on automatically. If the system you're considering doesn't clearly list this feature, it almost certainly doesn't have this feature. Never purchase a rear view camera system without this feature.

2. Field of View

The field of view of the camera is determined by a number of factors like the image sensor size, type and the lens focal length. Like a normal camera the bigger the sensor the better the quality of the picture, the better it performs in low light and the wider the field of view it can achieve. A 1/4” sensor can only deliver a 60 to 90 deg field of view while a 1/3” should deliver around 120deg.

90deg is the minimum field of view you should accept, but seeing there are so many units that perform better I would not purchase anything less than 120 deg. 1/3” image sensor and a 120 deg field of view should be your baseline. There are super wide-angle units of 180 and even 210 on the market. Sounds grea,t but these units create a fisheye lens effect and it is virtually impossible to use them to reverse. Imagine reversing by looking through the peephole in your front door, you are guaranteed to have an accident at some point.

3. Screen Size

No matter which rear view mirror camera system display you choose, it’s likely to be smaller than some of the standalone models just because the display has to fit inside the dimensions of the mirror.  A smaller display makes it more difficult to see the details in the image which are important in the case of a back up camera display.  Look for a monitor size in the mirror of at least 4.3 inches in order to get the best image possible.

4. Video Inputs

Some cameras come with multiple video inputs that can handle the inputs of both a car rear view camera and a car DVD player for instance.  If that’s important to you, look for dual video inputs on any display you buy.

5. Bluetooth Hands-Free

Some displays come with additional options that can be very helpful including Bluetooth hands-free capability. Bluetooth hands-free model can be connected to a Bluetooth-capable smartphone so that you can use your phone without taking your hands off the wheel.  It’s a great safety feature and one that can prevent you from getting a ticket in states where hands-free is required.

Becoming Familiar with Your Mini GPS Tracker

After considering all the options, making your list, checking it twice, and finding out which GPS receivers are naughty and nice, you’ve finally come to that blessed event where you’re the proud owner of a GPS receiver. But before you step out the door for a 100-mile wilderness trek or cross-country road trip, intent on relying on your new electronic gadget as a guide, be sure spend some time getting to know your Mini GPS Trackers . A good place to start your GPS familiarization process is with the user manual. Many GPS receivers have a quick-start guide that gets you up and running in a matter of minutes. These guides are perfect for those impatient, got-to-haveit-now people; however, I suggest that you also take the time to read the full user manual. Otherwise, you could miss out on some important information contained in the full user manual. In addition to the user manual, this section will also help you become familiar with your GPS receiver so you can get the most out of it.

Obviously, because so many GPS receiver models are on the market, don’t expect to find detailed operating procedures for your specific model here: You need your user manual for that. What you can expect is basic information that applies to most GPS receivers, including some things most user manuals don’t mention. Based on a number of years of search and rescue experience, I can list numerous occasions when hunters and hikers thought that their GPS receiver was some kind of magic talisman that would prevent them from getting lost. And quite often when the search teams finally found them, they had no clue whatsoever how to properly use their GPS receiver. Powering Your GPS Receiver Before you can start using your GPS receiver, you obviously need to give it some power. For portable GPS receivers, that usually means AA or AAA batteries. Manufacturers all give estimated battery lifetimes for their GPS receivers, but the actual number of hours a GPS receiver will run depends on how it’s being used. For example, with the backlight on, battery life goes down because more power is consumed. In addition, what type of batteries you’re using can also make a difference. Battery saver mode Some

Portable GPS

have a battery saver mode that can greatly extend the life of your batteries.

Normally, a Personal Tracking Devices processes satellite data every second and determines your speed and location. Based on this information, the GPS receiver predicts where you should be the next time it gets satellite data. If the prediction is close to your actual position and battery saver mode is turned on, the GPS receiver will start receiving satellite signals every five seconds or so instead of every second. In addition, some of the internal electronics are turned off during this wait period. Because a reduced amount of power is needed, the battery life is extended. The GPS receiver continues to access satellite data every five seconds until the predicted location isn’t accurate anymore, at which time it switches back to receiving data every second, starting the process over again. Some GPS receivers provide you with a number of choices of how often satellite data is received. The more seconds, the more battery efficient the receiver is.

How parents Can Benefit from GPS Kids Phone

It's not new in a country where people take advantage of GPS-enabled cell phones to keep tabs of their loved ones' whereabouts. Personal GPS Tracker have been known to not work very well indoors and generally give the pinpoint accuracy of a few yards--not good enough to indicate definite physical contact. Thanks to modern technology, cell phones can now be tracked by a GPS chip. Today, GPS tracking and reporting technology is integrated into every device from smartphones to sneakers and watches. As this emerging technology goes mainstream, parents are starting to rely on GPS to ensure the safety and security of their children on their way to school.

How Will It Benefit Schools?

The heightened concern nationwide about security in the wake of campus shootings and other high-profile incidents, combined with the technical abilities of smart phones, is driving the creation and demand for the safety apps. Campus police are praising some of the apps for creating a new trove of incident alerts and detailed tips, complete with GPS coordinates, detailed physical descriptions, and photos of potential lawbreakers or license plates.It makes perfect sense to have GPS tracking technology installed in school buses to aid in the safety of children and drivers. Parents can receive text messages when their children are approaching the bus stop or when the school bus reaches a certain distance. Parents can also be notified when a child has reached the bus stop and is ready to be picked up.

School districts and authorities can benefit from school buses equipped with GPS tracking devices in several ways. With GPS tracking, they can reduce fuel costs, review time punches and ensure the safety of students. A GPS equipped school bus has the ability to map out the most efficient route for the bus driver, avoiding wrong turns or high traffic areas. This results in significant fuel savings since the bus driver would be traveling the shortest route possible. It also means immediate ROI since school districts can save money on paying bus drivers because travel time is greatly reduced.

GPS Tracker Device can help protect children from being abducted. Since cases of missing children are on the rise, utilizing tracking technology to help keep children safe is a benefit to both school officials and parents. A good GPS tracking device can confirm whether a child was on an assigned bus and if they got off the bus. Knowing that a child is on their assigned bus and traveling to the right location provides assurance to parents and can help law enforcement authorities in the event that the child was not where they were supposed to be.

The advantages of Using 3G GPS Tracking for fleet management

Why Businesses Should Use a 3G GPS Vehicle Tracking Device 

By the end of 2016 mobile operators from Australia, the USA and Canada are going to turn off their 2nd generation base stations. More countries will follow their example in 2017 and 2018. For GPS tracking service providers the risk depends much on their business model. If the monthly fee of the offered service generates the large part of the company’s income, the threat of 2G shutdown is essential. Such companies build the subscriber base over the years. They attract customers spending a lot of money on advertising. The profit from the equipment sales and its installation is often minimal. Furthermore, talking about the equipment installation on hundreds and thousands of cars, the time costs are high. GPS trackers that are used to manage fleet and other similar purposes should be fast and efficient. Good thing 3G GPS tracker for business is already available. You may be wondering why 3G when there is already what we call the 4G network. The reason is that the two vary depending on the network provider and the kind of mobile phone you are using. Besides, you don’t need a 4G connectivity when your phone doesn’t support it or when you’re in an area where there is no 4G network coverage. You will only need this ultra-fast connection if you are into music and video streaming. For basic apps like GPS, e-mail, or social networking, 3G connectivity is more than enough for you. 

2G vs 3G GPS Tracker 

But if you’re still using a 2G connectivity for your GPS tracking needs, you’re an old school. It’s highly recommended that you upgrade your device. It’s time to start using 3G GPS tracker for business for smooth-flowing operations. For one thing, 2G connectivity can only give you less than 50,000 bits per second of data transmission, but while with 3G network, you can have a speed of over 4 million bits per second. The faster data speeds in 3G network lead to timely information and accurate monitoring. It also helps in precise tracking using 3G towers. In some cases, it complements satellite tracking to make tracking more accurate. The enhanced security of 3G network ensures data is secure. For your fleet business, you can’t afford to lose millions of data per second! Speed is essential when it comes to fleet tracking. The use of 3G GPS Tracker China Manufacturer offers a commercial opportunity for many businesses. Individuals can now monitor their cars remotely and also track its fuel levels, engine condition to know exactly when the car requires service. The advancement in the motion and distance sensors has helped passengers know the distance which helps them make an informed decision. Businesses also have better control over billing and mileage of the vehicle to benchmark their business and plan on operational costs quite effectively. 

Practical recommendations on 3G jump 

If GPS tracking service fees are a significant part of your income, the time before 2G shutdown must be used with maximum efficiency. Start prepare the business as soon as possible. If you have 4-5 years or more prior to the transition. Offer the customers not only 2G devices but 3G ones as well. 1. If your supplier is not ready to offer 3G devices, look for manufacturers who have already offered 2G trackers. Likely their products have the advantages in other technological aspects. You have time for negotiations and testing. 2. Tell your customers that 3G devices price is not so high. It is not much more expensive than 2G trackers. If the customers buy the “next G” devices now, they will be prepared for the transition. There will have no need to purchase and install new equipment in just a couple of years. 3. Show the benefits of 3G such as connection reliability due to 3G network coverage increasing and the lack of 2G networks development. Suchwise, you and your customers will get rid of unnecessary costs in the future and eliminate the risk of losing the subscriber base. Just 2-3 years left. Stop selling 2G GPS trackers and start change the old сustomer’s devices to the “next G” ones. 1. Consider plan B to extend the transitional period. If your mobile operator wants to be one of the first who canceling 2G, sign a contract with another mobile network carrier. After the shutdown it will be enough to replace the SIM-card and gain some time. 2. Inform the old customers of the new 3G devices assortment. Show the devices advantages over existing 2G GPS-trackers. “G” is not the only benefit, tell about the functions. 3. Due to the large 3G device purchase, you can get additional discount from suppliers. If your current supplier is not ready for 3G, find another one and test its equipment. 4. Offer special promotions on equipment exchange. For example, it may be a free new device installation or exchange discounts. Of course you have to pay for this, it keeps your customer base, you will not face a heavy workload during 2G shutdown. Only few month ahead. Do your best to move your customers to 3G. 1. Take a sufficient number of SIM cards from the mobile operator who are going to provide 2G service for some time. This is for the customers who will decide to change the equipment at the eleventh hour. 2.

Using the GNIS for your GPS Tracking Device

When you start using a Personal GPS Homing Device , you’ll soon discover that it’s pretty numbers-oriented. There’s time, speed, distance, altitude, and (of course) the location coordinates. But quite often you’ll want names to go with those numbers. Or you might need to convert those coordinate numbers into another format. Read here to discover how to locate places by their names and get their coordinates (and other information) and how to easily convert coordinates from one coordinate system to another.

Finding Your Way with Online Gazetteers Sometimes you need a little bit more information about a location. You know a place name, but you don’t know exactly where the place is located. You’ve heard about a place but don’t know whether it’s a mountain peak, a river, or a town. You generally know where a place is, but you need the exact latitude and longitude or Universal Transverse Mercator (UTM) coordinates. In these cases, you can turn to a gazetteer, which is a collection of place names with such useful data as geographic coordinates, elevation, and feature type. Gazetteers are usually published as books, but digital versions are available. The U.S. government has two free online gazetteer services:

Using the Geographic Names Information System (GPS Solution ) The Geographic Names Information System (GNIS) is the federal repository of geographic name information. The database contains information on nearly 2 million physical and cultural geographic features in the United States and its territories: a city, dam, island, school, or any other designated feature type. The GNIS search page has a number of different data fields that you can use to narrow down your search, including Feature Name: This is the name of the feature you’re looking for. This can be either the whole name or a part of the name. Feature name searches aren’t case sensitive. Query Variant Name: Some features have other names in addition to their primary name. If you select the Yes radio button, records with matched variant names are displayed. State or Territory: From this drop-down list, select the state or territory where the feature is located County Name: If you click the County Name button, a drop-down list box shows all the counties in the currently selected state. If you know the county where the feature is located, enter it to speed up your search. Feature Type: The Feature Type drop-down list box contains all the feature types, such as bridges, canals, lakes, and populated places. If you know what the feature is, select its type. Elevation Range: The Elevation Range text boxes let you search for features that occur at a certain height range; use feet when entering the range values. Topo Map Name: You can confine a search to features only found within a United States Geological Survey ( Portable GPS ) 7.5 minute topographic map by entering the map’s exact name.

The more you narrow a search, the faster it is. For example, if you know the county where a feature is located, select it. If you don’t know much information about the feature, be patient. The GNIS server can be pretty slow. If GNIS finds any records that match your search criteria, it lists all the matching features.

Use Motorcycle GPS Tracker Device to Protect Your Motorcycle from Thieves

Nothing beats the thrill of riding your motorcycle down the highway. Motorcycles can get into places other vehicles cannot. They have great fuel economy. It just feels great riding them in the open air. This list of great things about motorcycles can go on and on.

Popular and expensive brand or not, despite being locked in your garage, your motorcycle can still be snatched. Motorcycle theft is a huge problem in any country today. According to statistics, 192 motorcycles are stolen everyday and only 9% of them are successfully retrieved.Over 45,000 bikes are stolen in the United States every year. That’s more than one every 12 minutes! Even worse, most bikes are never recovered since they are pieced out and sold for parts (or rebuilt onto a legitimate frame). In the UK, it’s 21.69%. If your bike is one of the exotic types with expensive parts, then yours has a lower chance of recovery. According to National Crime Intelligence Service or NCIS UK, it only takes about 20 seconds for thieves to snatch a motorcycle. Most of the crimes are executed in the city, and what’s alarming is 80% of the stolen bikes are grabbed from the owner’s own garage.

However, the same great things that make them great also make them prime targets for thieves. There is nothing standing in the way between a potential thief and your motorcycle’s ignition. Fortunately, you can use a Motorcycle GPS Tracker if the unthinkable happens.

Finally, here are 5 useful Motorcycle Anti-Theft Tips for you.

1. Lead Them Not Into Temptation.

The less your bike is seen, the less likely a thief will cozy up to it. If you don't have a garage, keep it covered. Not knowing what's underneath makes it harder to assess the difficulty of stealing it ot to know if it's even a bike they want. By putting a BMW cover on your Harley, you can also create the impression that it is a bike that is less likely to be stolen than what it actually is.

2. Steer Clear

Although readily defeated, your bike's steering lock can be a first-step defense and will discourage easy maneuvering of the bike. It is even more useful if your ignition and steering locks are separate, so the thief needs to defeat two locks to escape with your scooter.

3. The Power Of Two

It's best to use two or more locks of different types in addition to your bike's built-in lock(s). Unless a thief has surveiled your bike, he probably won't be prepared to tackle different kinds of locks. And if one of them anchors the bike to something immovable, a gang won't be able to carry it to a truck.

4. Make Some Noise

Alarms may seem like a good way to attract attention to the fact that someone is attempting to purloin your bike, but in most places we have gotten so used to false alarms that people don't investigate or even bother to look. But everyone pays attention to sounds of destruction—such as breaking glass. A large stack of beer bottles with a trip wire makes a sound that everyone will investigate when it gets tipped over.

5. So That's The Key!

Make a record of your key numbers, then file them off the locks if they're stamped on. Anyone with a number can have a key cut to fit.

GPS Car Tracker in China face 3G challenge

3G GPS Tracker are definitely better options for today’s businesses, especially in countries where there is a foreseeable time frame as to when the local 2G network will become obsolete. The global process of 2G networks shutdown has been already started. By the end of 2016 mobile operators from Australia, the USA and Canada are going to turn off their 2nd generation base stations. More countries will follow their example in 2017 and 2018. It saves significant labor and logistics expenses in the long run since deploying 3G devices now means less 2G devices to replace when the time comes. Installing 3G devices now also means both GPS telematics services will not be interrupted in the future when 2G network becomes unavailable, and revenue-generating corporate assets will not need to be called back off the road for putting in a new tracking device. 3G mobile networks are quite threadbare. Everybody uses it in smartphones while killing time in a bus or at traffic jams. Even 4G is not novel for people who are engaged themselves with this “nowadays bane”. However, most GPS Manufacturers In China are still using 2G like technical progress had never happened to them. This arrearage has a simple explanation. First of all, GPS devices with all their modernity didn’t work much with bulk digital data. Most trackers used only for positioning and transmitting some simple information like battery status. Look at mobile tracking apps at least. However, a request for comprehensive data transmitting becomes a trend of the last years. The market leaders offer two-sided mutual voice communication and, that is more important, transport video control options. 3G (and even 4G) networks are necessary for its reliable work. The growing demand on the newest fleet management in IoT features force manufacturers to make their devices ready for that challenge. The second reason is that many countries have plans to scale down 2G networks because it takes a lot of resources to support them only for a few niches of telecommunication like GPS tracking or car alarms. That’s why these devices should follow the progress. We sorted out Two Concox 3G GPS Vehicle Tracking Device that already have become popular. 1. GT06E 3G GPS Tracker Multifunctional Tracking Device GT06E gets you a step ahead with 3G capabilities and better tracking, ideal for fleet tracking and management.Utilizing cutting-edge GPS technology, the GT06E features not only traditional tracking functions as tele-cutoff petrol, geo-fence, SOS alarm, overspeed alert, but optional digital outputs for door detection, vehicle pinpoint by audio-visual alert, external power voltage etc. 2. GV20 3G Vehicle GPS Tracker With finest craftsmanship, GV20 is a fully-featured, highly competitive and cost effective 3G GPS tracker developed for vehicle, motor and bus tracking. It offers you crystal clear real-time tracking details, including location, route, flashback, etc., even in tough environment. It supports remote fuel/power cutoff and gives you insight on ignition status. Wherever you go, its instant alert notifications allow you to react accordingly and immediately. The pittance of 3G GPS trackers is a matter of time. Exacting customers want the newest features for their business and assets and they wait for the next steps from hardware manufacturers. “Improvements in technology can only aim to make the workplace run even smoother. If your fleet is still functioning with 2G connectivity, you won’t be getting the accurate data. You must switch to 3G GPS tracker,” reported Concox representative.

Wireless IP Camera - Video Management System Software (VMS)

Isolated physical security subsystems do not include a consolidated view of activity, alerts, alarms, incidents, events, and security threats at the enterprise level. That must be determined by operations with obstacles such as time constraints; limited data sharing creates a poor compliance and audit of approved security processes. There is also a high cost of staff to monitor a multitude of CCTV video streams, with several hours or even days attempting to retrieve and manage any possible stored video footage. Although the cost of proprietary hardware, maintenance, and support is high, any physically installed camera at a valuable area of coverage is a much-needed asset. A physical security information management software system, or PSIM (Wireless Security Cameras ), integrates existing and future security subsystems, making them “future-proof” for operations. It doesn’t matter what system or how many different systems are working behind the curtain; all events and incidents are displayed on a single dynamic interface that can incorporate maps, GPS, and alarm management.

The core engine that drives the single interface, adds to the intelligence behind it, and manages video archiving is the video management system (VMS) software. This application is not just the interface to the Wireless Camera and the digital archives; it is also the “eyes on the street” for validation of other physical security subsystems that would go unchecked with the integration of synchronous cameras. Behind the scenes of any company is the software they use, sometimes referred to as an application and other times as a system. These applications make it possible to improve business processes and increase productivity and efficiencies. A very good example is this word processor I am using, as opposed to a typewriter, which does not provide such options as cut and paste, delete, and undo, nor does it have a built-in dictionary and thesaurus. This word processing software has made me smarter and has given me tools to work faster.

Applications are now a necessity for allowing any business to thrive, and like all software, they need hardware to operate. Some applications require installation on top of other host applications, such as an operating system. These are applications that are usually developed to be an interface for better business solutions. Applications are also developed to be embedded within a hardware chip to perform a single function, such as the firmware that converts analog video into digital video in a digital video encoder or GSM Camera . Many digital video management software applications are available. The key to choosing the right application rests entirely on the system requirements, so the more detail included in the project requirements, the easier it is to make a decision. The many choices in the market (far too many to even consider exploring here) create serious challenges as organizations sift through all the available VMS options. In a business environment, making a wrong software decision can increase organizational risk, cause inefficiencies, and eventually require costly upgrades. VMS is constantly evolving to keep up with market trends and demands. Originally developed as an interface to monitor video surveillance camera streams, VMS’s convergence of telecommunications, media, and security provides a new proficiency that not only protects business and property but people’s lives as well.

Choosing the Rear View Mirror GPS DVR locations is very important

Crimes against elevator passengers have increased significantly in recent years; the threat represents a potentially high liability to the owner of the elevator's building. The use of Rear View Mirror Camera in elevators reduces the risk of harm being perpetrated on passengers in elevators. From an asset-protection point of view, elevators represent a valuable capital investment and should be under surveillance to deter vio- lators from defacing and vandalizing them. This application describes the equipment to monitor elevator cabs and the lobby. A passenger entering an elevator with a stranger is temporarily "locked in" with the person until the elevator stops and the door opens on another floor. This serious problem has come about because almost all elevators are automatically controlled and there are no elevator operators. Years ago the elevator operator performed the function (whether consciously or not) of visual surveillance in the "locked" elevator cab. No one was ever alone in the elevator. The operator was a deterrent who could also assist in preventing molestations, robberies, and vandalism. This inherent protection now absent on most elevators is returned via the use of overt CCTV and audio intercom systems.

Applications covered in this section apply to facilities used by governmental agencies, manufacturers and industrial companies, and business services. CCTV surveillance applications include lobbies, elevators, offices, rear doors, shipping areas, hallways, and warehouses. Temporary and permanent covert CCTV systems are used in installations for viewing the general public entering a facility as well as monitoring employees. Wide-FOV optics and zoom lenses are used for parking lots and perimeter-fence-line environments. One Wireless Camera is located in the lobby close to the ceiling and looks at the entrance door and lobby with a lens having an FOV wide enough to see at least half of the lobby, the receptionist, and the front door. The second camera on the opposite wall views the other half of the lobby and the internal access door. The third camera is covertly mounted in a wall-mounted clock. Aside from choosing the equipment, choosing the camera locations is most important.

The camera/lens should not be pointed in the direction of a bright light or the sun or toward an outside door or window if possible. If the sunlight enters the camera lens directly, blooming (white areas in scene) can obliterate a part of the scene. Newvicon, silicon tube, and CCD solidstate cameras using automatic-iris lenses or CCD cameras using shuttering will compensate for light-level changes but do not always compensate well for a very bright spot in a scene. A person under surveillance who is back-illuminated by light from an exterior window or door is usually seen on the monitor as a black silhouette and cannot be identified. The video signals from the two overt GSM Security camera and covert camera in the lobby with the receptionist are transmitted to one or two monitors located at the remote security guard station. The two overt cameras view people entering and exiting through the front entrance door, most of the lobby, the receptionist, and the internal access door. The third covert camera provides backup in the event the overt cameras are rendered inoperative.

Early commercial GPS Tracking Device industry was influenced by highprecision survey

Since the early commercial Wireless GPS Tracking Device industry was heavily influenced by highprecision survey and mapping applications, there has been much research on GPS multipath. But the multipath that has been studied is mostly two-ray multipath, in which the direct and reflected signals are both present at the antenna. The problem faced by high sensitivity GPS is not so much two-ray multipath, in which there is a longer delay from the reflected path, but rather pure reflections in the absence of a detectable direct signal. There has recently been an increase in attention paid to the urban canyon problem. See, for example, though the focus is still mostly on two-ray multipath. We must also note that the reflected signal at the antenna is not necessarily coming from a single source. In fact, it is usually not. Usually there are many reflected paths that lead to the antenna, and thus, if the signals interfere constructively, you will observe relatively strong signals that are nonetheless pure reflections.

The fields in the ionosphere model GPS assistance data is considered to be global in nature because it is not specific to any particular satellites. The LS simply uses the data that it has cached from the GRS and encodes it into the format specific to the protocol being used. Instead of encoding this data type on a per-request basis, the LS will generally encode it as a changed version is received from the GRS. That way, it does not need to be encoded for every request, but is just copied to the appropriate place in the bit buffer for the message being composed by the LS. This data type is only applicable to handset-based A-GPS, which uses it for part of the position calculation and may also use it to calculate acquisition data. The next question after creating the Route and Position methods is how to fill a route with plausible real-world data. The obvious solution is a global navigation satellite system (GNSS) or global positioning system (GPS). While Electronic Tracking Device is the currently used shortened acronym, it was derived from NAVSTAR GPS (Navigation System for Timing and Ranging), the first actual global positioning system, launched in 1971.

About 24 satellites orbit the earth. With at least four satellites (three for position, one for time) in sight, a GPS Tracking Device is able to calculate its (lat, lon) location with a certain precision and speed, depending on a number of factors. In addition, many GPS devices are able to mark and record (or even transmit) the current position. More sophisticated units allow the user to create and store routes as well as load (digital) maps to be displayed on a small screen. A simple mouse could be considered a GPS representing Position in the software world. GPS systems are becoming more and more prevalent and can be found in a growing number of devices (cell phones). From the abstracted project view, a GPS is simply an arbitrary technical system to enable electronic receivers to determine their current longitude, latitude, and elevation information. Part of our task is to create a GPS receiver for the software world, a GPS unit. Every RO will have a built-in virtual GPS receiver.

Indoor and outdoor camera housings protect Wireless Home Cameras

When very large volumes of video images need to be recorded, an optical disk system is used. Optical disks have a much larger video image database capacity than magnetic disks given the same physical space they occupy. These disks can record hundreds of times longer than their magnetic counterparts. Most video security systems require additional accessories and equipment, including: (1) camera housings, (2) camera pan/tilt mechanisms and mounts, (3) Wireless Camera identifiers, (4) VMDs, (5) image splitters/inserters, and (6) image combiners. The two accessories most often used with the basic camera, monitor and transmission link, described previously are camera housings and pan/tilt mounts. Outdoor housings are used to protect the camera and lens from vandalism and the environment. Indoor housings are used primarily to prevent vandalism and for aesthetic reasons. The motorized pan/tilt mechanisms rotate and point the system camera and lens via commands from a remote control console.

Indoor and outdoor Wireless Security Camera System housings protect cameras and lenses from dirt, dust, harmful chemicals, the environment, and vandalism. The most common housings are rectangular metal or plastic products, formed from high impact indoor or outdoor plastic, painted steel, or stainless steel. Other shapes and types include cylindrical (tube), corner-mount, ceiling- mount, and dome housings. Monitors are often considered an unimportant investment in CCTV, compared to the other parts of a CCTV system. It is, however, very clear that if a monitor is not of equal or better quality than a camera, the overall system quality will be diminished. Simple but worthwhile advice is: pay as much attention to your monitor as you do to your camera selection. Monitors display a video signal from a camera after it has gone through the transmission and switching media. The camera might be of excellent quality and resolution, but if the monitor does not reproduce equally or better than the camera, the whole system loses in quality. In CCTV, as in broadcast TV, the majority of monitor display units are CRTs, which means they use cathode ray tube technology, designed to convert the electrical information contained in the video signal into visual information. Today, there are many alternatives to CRTs, such as liquid crystal display (LCD) monitors, plasma display, and rear projection monitors, but the most popular are still the CRT monitors.

In a small GPS Rear View Mirror , the entire video system and computer equipment can have backup power provided at reasonable cost. In medium-to-large systems, it is often difficult to justify 100% backup power for all video and security equipment. A judgment must be made regarding which equipment will have backup power, as determined by its strategic value in the overall installation and security plan. Any security system has certain essential camera, monitor, and recording equipment that must continue operating in the event of a power disturbance or blackout. There are other categories of equipment that, while useful in normal security functions, can afford to be inoperative without jeopardizing the primary assets or safety of the facility. Essential items might include access control and identification equipment at critical points around the facility, internal video surveillance cameras in areas critical to the operation of the facility or protection of valuable assets, and any monitoring and recording equipment for these scenes.
