The all-new Nissan Note features an intelligent self-cleaning rear view camera that ensures systems like Lane Departure Warning, Blind Spot Warning and Moving Object Detection are fully optimized.

In order to make these premium tech features accessible to the B-segment, Nissan has developed all the functions of the Safety Shield to rely on only the rear view camera. However, with so many functions depending on on the perfect operation of the wide angle rear view camera, Nissan’s engineers realized the lens would need to be clear of dust and dirt at all times.

"We couldn't allow the camera's lens to get dirty at any time because it would detract from the technology's performance in everyday use with the customer. However, we didn't want the task of cleaning the lens to fall at the hands of the driver, so the intelligent self-cleaning system was developed," explains Richard Picton, Nissan's Safety Shield engineer.

The rear camera is kept clear of accumulated dirt or water drops with no input from the driver, thanks to a fully automated function. According to Nissan, the self-cleaning system is intelligent enough to know the difference between mud or simply rain water. It uses a tiny water system and compressed air blower to clear the lens.

"Light dust is best cleared with a blast of air. A splash of muddy water from a puddle will need a full wash, so water is squirted at the lens and blown off again with air," says Picton.

You can see for yourself how the rear-view camera works in the video below.
