Taking a reverse in a big car will surely give headaches to many experienced drivers. Novice ones will simply hit it on the rear bumper or will take multiple for- aft movements to steer clear of tight passages. Rear view camera is one of the most convenient accessory to have in your car if not given by the car manufacturer. The camera is mounted on the rear bumper or tailgate in a downward angle to give a good view of obstacles behind the vehicle that are not visible to the driver. Reverse cameras have either a wide angle lens or a fish eye lens to give a slightly distorted but stretched view of the surroundings behind the vehicle.
During night time placing the reverse gear lightens the reverse lamps to lit up and give clear view of the back. Today night vision cameras are also available that provide as bright a view as is seen under broad day light.
Best Mounting location and sensor types
Most rear-view cameras either use CCD or CMOS sensors. The sensors convert light to signal in two different ways: CCD is essentially analog, and CMOS is digital. Generally speaking, a CMOS sensor draws less power and is better in low light than a CCD sensor, but a CCD sensor is slightly better adapted to handle fluctuating lighting scenarios than a CMOS sensor. Depending on the types of environments where you typically drive, the difference may be incidental.
Generally, rear-view cameras provide a healthy horizontal viewing angle, with some as expansive as 190-degrees. Naturally, the wider you go, the more you’ll see behind you at a glance.
This is just what it sounds like. The view in your monitor is reversed to mimic that of a rear-view mirror. With some cameras, this is a selectable feature.
If you have an inset area on the rear of your car, chances are you can use an angled lip-mount camera which is a little more subtle and prevents dirt accumulation during rainy season or on muddy roads.
License plate mounting
Mounting cameras on the rear license plate is also one of the good location. Care needs to be taken that the height of camera is atleast 60 cm above the ground so as to get best view of the rear obstacles. Lower camera height is also prone to dirt accumulation and vision hindrance during rainy season.
For spaces that are very restrictive this style takes the most apt approach, providing an adjustable bracket that lets you mount your camera wherever you see fit.
Aftermarket parking sensors and rear-view camera displays can also be mated to the LCD display of an aftermarket multimedia infotainment system to display image from parking sensors as well as that of the rear-view camera.
