Guardian Alert Gives Visual, Audible Warnings The Guardian Alert from Sense Technologies Inc is a patented, environmentally sealed unit that provides a driver visual and audible warnings of objects up to 12 feet behind a vehicle.
This unit is self-contained and fully operational with the connection of two wires. Its interior indicator can be mounted in any location within the driver's compartment that has access to the automotive electrical system.
The Guardian Alert is powered by a vehicle's reverse light circuitry, making it instantly activated once the vehicle is put into reverse and automatically shutting off when in neutral or a forward gear.
