nVISION offers a wide range of driver awareness solutions that help with visibility, warning, and detection. The nVISION Rearview Camera System features SmartZone Sensing technology that actively senses the location (left, middle, right) of an obstruction. Green, yellow, and red indicators on each side of the monitor let you know how far the object is away from the vehicle. This rearview camera system detects objects up to 5.5 feet away. Sensors are adjustable to provide maximum detection for your specific vehicle. The wide angle camera adjusts for optimal viewing and has the ability to adjust up/down for maximum vertical view. It can also adjust left/right for exact horizontal viewing. This allows you to move out of the way of the lift gate. This item is also easy to install and easily mounts behind your license plate.
