If Subaru uses a pair of front-facing cameras called the EyeSight, Nissan, on the other hand, has mounted a single rear-facing camera on the 2013 Altima that has the capability of handling the function of three sensors.
Rear cameras on other cars are only used for giving the driver a view of the vehicle’s back side. But the Altima’s rear camera also provides a lane departure warning system, blind spot monitoring, and rear proximity detection. If the driver accidentally goes out of the marked lane, the system gives a beep. It also alerts the driver of blind spots using its ultra-wide lens. Lastly, it will warn the driver if motion is detected behind the car, thus preventing the car from hitting a pedestrian walking across the rear of the vehicle.
Watch the video below on how the system works:
Aside from the car safety system, the camera automatically cleans itself by dropping a small amount of cleaning fluid on its lens, and then dried by puffing a burst of air from an air compressor. With this feature, the camera maintains its accuracy and avoids reporting false positives.
With this all-in-one camera-based safety system, Nissan will be able to offer this feature as an inexpensive driver aid to all potential buyers of the 2013 Altima. Although, we’ll all have to wait for the pricing of the car to be announced.[CNET]
