Reversing cameras are designed in a way which is distinctly different from other cameras.
This is because the image is horizontally flipped so the it is, effectively, a mirror image.
The reason for this is that the driver and reversing cameras face different directions – and without it, the driver’s left reversing camera’s right.
The mirrored image makes it the same as the actual mirrors in the vehicle.
A reversing camera system usually has a fish eye lens and a wide angle lens.
Reversing cameras point at a downwards angle, to see ground objects as well as walls and large obstacles.
