GPS vehicle tracking systems have a variety of uses and applications. These devices tend to be classed as either "Past Track” or "Real Time” car tracking systems. Essentially, the difference lies in the accessibility and availability of the data from the tracking device.
Past Track vehicle tracking devices (or history loggers as otherwise referred to) store the data about a vehicle’s direction, distance, speed, length of stops etc to the internal flash memory of the unit that can later be retrieved from the vehicle and the information downloaded to a computer for review. Advancements in Past Track devices now use integrated Bluetooth in which the data can also be transferred wireless to a nearby laptop without the need to retrieve the actual unit.
Real Time vehicle tracking devices (whether the unit is wired into the vehicle or deployed underneath the carriage) allow you to monitor and track a vehicles movements as "the action happens" by which the data is quickly uploaded to a secure server which in turn translates the information to a tracking console which is viewed in full colour. The data is transferred so quickly it happens exactly in real time so you do not miss a beat! This type of tracking can be securely accessed by computer, PDA or mobile phone. Real Time tracking is generally much more visual and detailed.
Businesses may use both types of tracking devices to monitor their fleet ensuring that their vehicles are taking the shortest route between two points, thus saving fuel costs and improving customer efficiency and service. Many systems allow users to enter a destination address, find the closest vehicle to that address and plot the fastest and shortest route. Companies with employee "take-home" vehicles can also cut down on unauthorised use by using either type of vehicle tracking devices.
If the car tracking device is being used to track the movements of a spouse suspected of infidelity for example, a Past Track vehicle tracking device can be hidden in the car and then retrieved and later retrieved for reading its stored / logged data. A Real Time tracker can be used to monitor such movements as the action happens so you are able to track every turn, stop, start, and visually see the street the vehicle is moving along. Today's Real Time trackers are so advanced that battery life can exceed many weeks and even months before a recharge is required.
Real Time vehicle trackers whilst being more expensive, do have distinct advantages over Past Track units. For example, if you need to deploy a system to deter theft and improve the chances of recovering your stolen car, then a Past Track unit is not the correct solution because the tracker is stolen along with the car! Real Time vehicle tracking systems are the perfect choice if you need to know where your stolen car is the moment it is taken, and you can then direct the Police with incredible detail or give them temporary access to your tracking console in order for them to act more efficiently.
Some tracker are available on a P-A-Y-G basis meaning you control your own tracking costs and top-up only when needed but with some companies now offering "always active" unlimited tracking solution, it actually works out much cheaper in the long run to take this option.
Vehicle tracking systems can also be invaluable general motoring aids. Several motorists in the UK and USA have used the data gathered by installed car tracking devices to prove that their vehicle was traveling at a drastically different speed than that reported by police radar guns. One court case using vehicle tracking data enabled a motorist to demonstrate that he was traveling at 45mph (within the speed limit) and not the 62 mph the police officer noted on the citation.
All the above information is only a general insight as tracking systems can be incredibly diverse.
