The Arrow Tracker is a real-time vehicle tracking system designed for vehicle recovery, fleet management, and more.


The ultra-thin yet extremely durable Cool Arrow is a high-performance cellular device designed for remote control, monitoring and maintenance, early warning system and other applications. With an integrated CDMA 1X modem for wireless data communication and nationwide coverage. The built in high performance antennas for cellular radio make installation easy at the system or at the thermostat, with no need to connect to the local/private customer network.


No programming skills required: The Cool Arrow comes with easy-to- configure application software. Reports can be triggered periodically or in response to events such as changes in efficiency, office systems running after hours or on weekends, systems running all the time or not running at all. Notifications can be sent for maintenance, thermostat reprogramming, and more.


The Arrow’s interfaces include a line sensing using an optocoupler for sensing the presence of an ON signal from a thermostat or other device, and a normally closed solid state relay that can be used to open a circuit, for example to turn off a compressor or a fan or other.

Optional features include algorithms for energy savings, like the one provided by Smartcool.
