A rearview camera is an invaluable driver aid, helping to avoid obstacles and increasing parking safety. However, not every rearview camera offers high image quality and reliability. This article will teach you how to assess whether your rearview camera meets the required standards.
The History of Reversing Cameras
The first rearview camera was installed in the 1956 Buick Centurion, but it wasn't until the 21st century that they became popular in mass production. In 2002, Toyota introduced a standard rearview camera in the Prius, ushering in a standard feature that's now standard on most modern vehicles.
Key parameters of a good reversing camera
Image resolution
Image quality is crucial to the effectiveness of a rearview camera. Higher resolution cameras (at least 720p) provide better detail visibility.
Viewing angle
The wider the viewing angle, the more space the camera covers. A standard range is 120° to 180°.
Night mode
Good reversing cameras have a night vision function, so they can work effectively even in low light conditions.
Resistance to weather conditions
Reversing cameras should have a sealing rating of IP67 or higher to withstand rain, dust and changing temperatures.
Testing the reversing camera in practice
Checking the image in various conditions
You should test your camera both day and night. Good equipment will provide a clear image without excessive noise or blur.
Viewing angle assessment
Simply position your vehicle in front of the obstacle and check if the camera covers a large enough area.
Reaction to weather conditions
You can simulate rain by splashing water on the camera, or leave it out in the cold to see how it performs in extreme conditions.
Testing connection and compatibility
Not all cameras are compatible with every multimedia system. It's important to verify that the device is properly transmitting the signal to the vehicle's screen.
Comparison of popular models
| Model | Resolution | Viewing angle | Night mode | Immunity (IP) |
|---|---|---|---|---|
| Camera X | 1080p | 170° | Yes | IP68 |
| Y-camera | 720p | 140° | Yes | IP67 |
| Camera Z | 480p | 120° | NO | IP65 |
The most common problems and how to solve them
Poor image quality
This could be due to a dirty lens, poor camera quality, or wiring issues. Cleaning the lens and checking the cables may help.
Signal interference
Interference may be caused by power issues or a poor wireless connection. Checking the cables and repositioning the transmitter may resolve the issue.
The camera doesn't work at night
If the camera does not provide adequate visibility after dark, it is worth checking whether it has infrared LEDs and whether they are working.
Summary
A good reversing camera should offer high resolution, a wide viewing angle, night vision, and weather resistance. Testing its performance in practice allows you to assess whether it meets your expectations.
