A Vehicle Tracking System combines the use of automatic vehicle location in individual vehicles with software that collects these fleet data for a comprehensive picture of vehicle locations. Modern vehicle tracking systems commonly use GPS or GLONASS technology for locating the vehicle, but other types of automatic vehicle location technology can also be used. Vehicle information can be viewed on electronic maps via the Internet or specialized software. GPS tracker (reviser) takes this information and use trilateration to calculate the vehicle’s exact location. Now, with distance measurements from a few more satellites, the GPS tracker can determine the vehicle’s exact location and display it on the map and thus you can see it on your PC or smart phone screen. The GPS tracker must be locked on to the signal of at least 3 satellites to calculate location of the vehicle – latitude and longitude and vehicle movement. With four or more satellites in view, the GPS tracker can determine car’s location with three parameters – latitude, longitude and altitude. Once the car’s location has been determined, the GPS tracker can calculate other information, such as speed, track, trip distance, distance to destination, idle time, parking time and more.

A Vehicle Speed Limiter/Governor is a small, electronic device that restricts the top speed of a vehicle to 73 miles per hour.The device can be installed on most vehicle models manufactured after 1990, which allows you to control your teen's speed whether he or she drives a new or used car. Speed Limiter device is designed to limit the speed of vehicle like truck, school bus, car and so on. Nowadays, we are manufacturing and developing the devices . Speed Limiter will monitor the road speed of the vehicle by the installation of an electro-mechanical speed sensor. When the pre-defined speed is reached, the speed limiter will temporarily cause the engine to lose the power. The engine power will be reinstated at a speed not less than the pre-warning switch point, which is 5% below the set speed (without affecting the other performance parameters of the vehicle in any manner). Capable to limit the speed of the vehicle at the set speed as stipulated by the authority. Maximum tamper proof and fail safe against disconnection and failure of various components like power supply, speed sensors, mechanical actuator system, linkages etc. It Will not interfere with the brake systems of the vehicle.

In a case of getting a Vehicle Video Recorder, we reckon one that works most effectively at a reasonable price beats the cheapest one hands down. Camera surveillance is an investment; don't be fooled by the ridiculously low prices of some. That said, there are some benefits drivers should take note of when shopping for one. In the event of an accident that is through no fault of yours and with no witnesses to back you up against the other party, a vehicle video recorder will be able to work as video evidence which minimises ambiguity or false accusations. This way, making the usual exhausting and gruelling claims from insurance companies will be straightforward and hassle-free. Additionally, with the video camera installed in your car, it helps to ensure you that new drivers using your car are driving safely, more so if your son had just attained his driver's licence and cannot wait to get his hands on your wheels. Moreover, informing the new driver that a camera is installed in the car enforces him to abide by the traffic rules and take the necessary safety precautions. Parents can simply make use of the video footages training material to ensure that new drivers in the family adopt safe driving habits.
