Are you planing to buy and install rearview camera system for you own can or other vehicle, to improve reversing and parking safety and efficiency ? If yes, you definitely need help on how to choose the right rearview car camera system. Rearview camera system can be divided into wired rearview camera system and wireless rearview camera system ( also being called WiFi rearview camera system).
For individual buyer or if you want to DIY rear view camera system, you’d better buy wireless rear view camera system. In fact, even the wireless rear view camera system still have a lot of wires, they are called wireless because they don’t have the video cable you need to wire between the camera and the lcd display, which is the most difficult part for DIY rearview camera system, becuase it cost you a lot of time to route the video cable throughout the vehicle. Instead, the wireless rearview camera system has a digital singal transmitter with the camera and a singal receiver with the lcd video display.
Other than that, wireless rearview camera system and wired rearview camera systems are much same. They both need a power source to run the car backup camera , they both are usually wired to the backup lights so that the system activates when the vehicle is in reverse only.
Wireless rearview camera systems work best when the distance between the transmitter and receiver is the shortest. That means that they usually work better on smaller vehicles than on large SUVs or trucks.
Factors you should pay attention to when purchase a wireless rearview camera system
The heart of any rearview camera system is the camera itself. The reverse camera you choose should have a waterproof rating at least IP67, IP68 or IP69K will be better.
The camera should still work very well even at dark night, this functions usually requires the camera with built in infrared lights.
There are many types of cameras with a variety of mounting methods, but the easiest method for installation are the license plate bracket models. They prevent you from having to drill more holes to mount the camera.
Make sure that a camera mounted to the license plate bracket can be height adjusted via tilting or you may be stuck with a view to the rear that isn’t ideal.
Viewing angle is important when it comes to any car camera. Make sure the camera you choose has at 170 degree or better angle so that you can capture the whole area behind your vehicle.
Distance Detecting Line
Some cameras come with a built-in distance scale line display to help with backing up your vehicle and it is a really nice feature to have.
Video monitor sizes for back up cameras have gotten larger over time. A 7 inch lcd video display definitely provides a better picture of what’s behind you than a 3.5 inch display, but it also occupy a lot of space on your dashboard. But think about where you can put the display before you made the final decision. Remember that you only use it when you back up and otherwise it’s just going to mounted to your dashboard or windshield, and take up a lot of space. For any WiFi backup camera system you buy, the monitor should activate automatically when it receives a video signal and the signal from the rear view camera should have the first priority over other possible inputs.
