Vehicle accidents are quite common but due to advanced technology, we are able to access many safety devices that will reduce the risk of an accident. A common accident that a vehicle owner will face is knocking on something when you are reversing. The best solution for this is investing in a rearview camera.
It can be very hard to manoeuvre heavy and large vehicles like trucks and truck rear vision systems are crucial for the safety of the vehicle as well as others on the road. The damage that a heavy vehicle can do is a lot more than a smaller lightweight vehicle. One of the first things you need to evaluate in a rear vision camera is the field of view provided. This depends on the type of sensor, size of the image sensor, and the focal length of the lens. With a bigger sensor, you will be able to obtain a higher-quality photo. And especially in low light conditions, you will have a better view.
The minimum field of view that is acceptable is 900 but you should try to go for 1200 as it will perform better and give you more information. However, the wider the angle, it is not always better. In angles like 1800 or above, there is a fisheye lens effect that is created which will make it very difficult to reverse your vehicle.
Once you have decided on the specification of the sensor, you need to look at the type of monitors available in rear vision systems. Liquid crystal displays are better when it comes to quality but you need to look at the screen size as well. The bigger the screen size, the better you can see what is happening at the back. Sometimes you don’t need to purchase a unit with a monitor if your vehicle comes with its own SatNav unit. But you need to find a camera that is compatible with SatNav.
The rearview camera will have a CMOS sensor or a CCD. The latter has a higher quality video and is ideal for situations with low light. Because of this, they can be expensive as well. You can also check whether the camera comes with infrared night vision.
There are different types of rear view cameras as well. There are flush-mounted cameras that will be mounted onto a hole that is made in the body of the vehicle. It gives a clean look as all you can see is the lens and a narrow bezel.
However, the depth perception of the road will not be provided by the camera as it is level with the road. If this is a requirement for you, it is best to go for surface-mounted cameras. This is recommended for larger vehicles as it will give a good view and depth perception. You can also mount the camera onto your license plate hole. This way you don’t need to create an additional hole in the vehicle.
