Water-resistant Low Cost Vehicle Tracker

The ST350 is an economical tracking device which implements GPS and GPRS technologies. To cater recurring needs of insurance and fleet management markets in terms of recovery of stolen vehicle and history profiling on driver/vehicle, the ST350 is designed and deployed with its efficiently cost-competitive components like a simplified event line consisting of 1 input (or 1 ignition input) and 1 output.

Regardless of its cost reduction designing, the ST350 is a feature-rich device equipped with state-of-the-art systems such as 3-axis accelerometer, a super-sensitive GPS receiver (56 channel) and superior internal antennas for both GSM and GPS.

In addition to the basic tracking functions, this device has two-way communication capabilities which enable it to report about the vehicles event-lines status, accidents, door locking, panic button, temperature recording, etc. to a monitoring central and also let the operator activate many functions such as siren and immobilization.

Among its many capabilities the ST350 can implement services such as vehicle recovery, fleet management, route completion and monitoring, preventive maintenance of the vehicle, immediate assistance to drivers and driving skills.
