Most of the modern cars, especially the premium ones come with the inbuilt reversing sensor. Such a sensor senses any object as you move your car by sending out signals. If the signals come back, there is an object in the path, and it warns the driver on the display system on the dashboard. However, there are so many limitations. It cannot sense small objects and those objects on the sides.That is why a reserving camera is so much more useful. You actually get to see what you behind and on the sides, Depending on the viewing angle, you can check what is lying on the path, and you can place your car accurately. Moreover, there are bright LED lights available to light up the low-light areas.
