COBRA-2

Continuous Line Single Point Vehicle Crossing Detector with Output Relay

COBRA-2 vehicle crossing detector can be used in different civil and military applications for vehicle traffic detection and area surveillance. It is buried into the ground, as a line or loop, near or around the area of interest and designed to detect and measure traffic presence, volume and occupancy on the road or at an entrance to an area or building, and allows to take the necessary action. The detector does not react to nearby humans or animals.

COBRA-2 has a relay, FET or current loop output that can be used to trigger a pre-determined action to approaching or departing vehicles, such as set off a light or sound signal, open or close gates or doors, switch traffic and street lights on and off, etc.

If equipped with an additional module, COBRA-2 vehicle detector can send SMS notifications to up to 4 different users, alerting them of the location where a sensor was activated.
