Intec Video Systems has partnered with Preco Electronics, Inc. to provide our
customers with an active companion for their Rear Vision camera system.
PreView™ is a solid-state, pulsed radar object detection system designed to alert
vehicle operators to obstacles. The system detects both moving and stationary objects
in a pre-defined coverage area and reports the distance of the closest object via visual
range indicators and an audible signal to a vehicle operator.
The PreView consists of three major components: a set of environmentally sealed sensors, an operator display mounted in the cab of the vehicle, and interconnect adapter harnesses. The PreView radar is configured so that the power and signals to and from the radar system will be transmitted over the Intec camera system main cable, making installation more efficient.
The sensor assembly transmits and receives low power 5.8GHz radar signals.
It then processes the returned signals to determine if an object has reflected
any energy back to the sensor and reports this to the operator display. The sensor
is designed to process and report detections within 1/2 of a second allowing the vehicle
operator to quickly respond to any object within the detection zone. All connections to
a vehicle are made with the interface harness. Power is obtained from the vehicle reverse
circuit. The connection to the display unit is through a watertight connector. Power to
the operator display is provided through the sensor interface to the display. The sensor
RF output is pulse modulated so that it will not interfere with similar devices.
