VT-20, a professional GPS tracker for the control of vehicles with additional capabilities. The device allows on-line control of routes and vehicle speed, to receive information from sensors installed in the car, remotely controlled with Find''Secure Fleet Management System. Also with this tracker connects a microphone that allows you to have an idea of the atmosphere in the cabin. GPS-module based on SiRF Star III chip has a high sensitivity and even mepolise easily determines the location of the vehicle. Two of the four input devices operate in analog mode, which allows connect it to the sensors like fuel sensor, temperature sensor etc.With the superior sensitivity GPS module on board, the VT-20 can easily get a fix even in urban canyon condition.
