Backup warning device
-
Sense Technologies, Inc. says its Guardian Alert backup warning system for trucks is the first available microwave system that detects objects and indicates their distance behind a vehicle. The device, powered by a truck's reverse light circuitry, provides both visual and audible warnings for objects up to 3.7 m (12 ft) away and works in all weather and light conditions. The unit's 10.5 GHz transmitting frequency does not interfere with law enforcement radar or other devices. The detection zone extends 2.4 m (8 ft) in width and 1.8 m (6 ft) in height.
