Introduction: 8 Features of a Rear View Camera to Review Before Buying
A rear view camera is one of the best auto safety devices you can install in your car. You can get third-party backup cameras on the cheap that are also easy to install – a definite win for every automobile owner.
The thing is, not all rear view cameras are the same. Many have features differentiating one from the other, and you need to know these features if you want to find the perfect camera to fit your needs and justify its price tag:
Step 1: Field of Vision
This is how wide the camera can capture from its fixed position. This ranges anywhere from 70 degrees, which is very narrow, to 180 degrees, which is very wide. A wider view is typically preferred for reverse cameras, as they let you see more on your display. The camera does, however, need some depth for distance scale lines to be more accurate.
Step 2: Distance Scale Lines
Speaking of distance scale lines, these lines serve as guides for how close you are to bumping into an object. The skewed display of a wide-screen rear view camera may make objects appear further than they really are. These guidelines give you a means to better avoid objects that you see on your camera.
Step 3: Night Vision
Some rear view cameras come with night vision capabilities, allowing you to see objects in greater detail even in low-light conditions. This is pretty useful when you often park in dark, unlit areas.
Some reversing camera systems can be installed without using wires. You could, for example, have a rear view mirror camera display that is remotely connected to the camera on your license plate. This makes installing the whole setup a breeze, though you do need to change or recharge the battery on your device.
Step 4: Pan-Tilt-Zoom
Some rear view cameras come with the ability to actively pan, tilt and zoom the cameras. Though it can be useful for your average car, the importance of a PTZ camera becomes especially pronounced for larger vehicles like trucks and trailers. This is because using normal fixed cameras often results in dangerously wide blind spots that increase the risk of collision while backing up.
Water Resistance/Proofing – some rear backup cameras come with the ability to partially or even completely resist moisture. This is an especially important feature for those that live in areas prone to rain and flooding, as a heavy downpour could completely blanket the camera in water.
Step 5: Freeze Proofing
Those living in regions with winter seasons will definitely need to make sure their reversing cameras are freeze proofed. Without this protection, the sensitive electrical components of the average camera will break down a lot faster when exposed to bitter, freezing temperatures. If it’s totally unprotected, then even the physical components may be weak enough to be destroyed when winter comes rolling around.
Audio/Video Input – and last but definitely not the least is the ability to handle both audio and video capabilities. This is another feature that is especially useful for long, loud vehicles that require close coordination with someone else. Some even come with an intercom system that let you communicate in real-time – a very useful feature in a rear view camera when coordinating with a team offloading cargo from a truck.
