How To Choose Suitable Vehicle Backup Camera?

A, CCD vs. CMOS Image Sensor

1.The two types of image sensors that are available for rear view (backup) camera systems are the CCD ("charge coupled device") and CMOS ("complementary metal oxide semiconductor"). The type of image sensor that your rear view camera system uses will be the most important factor in determining picture quality. Besides the overall resolution, a camera that utilizes a CCD image sensor will provide significantly better images under very low and very bright lighting conditions.

2.Although there are some reasonably high quality CMOS image sensors, no CMOS image sensor will deliver the quality image that a CCD image sensor will provide. Many lower priced (and some more expensive) systems use the less expensive and inferior CMOS image sensor.

3. Given the option, you should always select a rear view camera system that utilizes a high quality CCD image sensor from a well known manufacturer. Sharp and Sony CCD image sensors are the best available.

B, Wired vs. Wireless

1.While the picture produced by a high quality wireless system may be okay when the vehicle is stationary, every wireless device (every one!) is susceptible to interference, and that interference will be worse when the vehicle is in motion. Because a wireless system transmits a video image through the air, instead of via a cable, there can be some interference from a variety of sources, including electrical interference, high power radio and television transmitters, and many other sources encountered as the vehicle moves.

2, I personally STRONGLY recommend a wired system.

C, Infrared Night Vision

1.This is probably one of the least understood features available, and yet, it is one of the most important features. Although a high quality camera (especially a high quality CCD camera) can provide a picture under a wide variety of lighting conditions (including very low light), it can't provide a clear picture in near or total darkness. That's where the infrared night vision illumination LEDs (light emitting diodes) come in.

2.On a high quality night vision equipped camera, the infrared LEDs turn on automatically whenever the ambient (background) light drops to a level that's too low for the image sensor to produce a high quality picture. The infrared LEDs operate at a light frequency that is well beyond the human eye's ability to see, but the image sensor in the camera is designed to detect this light just like the visible light that we can see.

D, Viewing Angle

1.Wide angle cameras give a wider viewing angle, and are generally more useful. 120 degrees or more gives a decent view, but smaller angles are still useful if mounted centrally.

E, Waterproof Grade

Rear view camera usually install on the exterior of a vehicle ,make sure the camera is truly waterproof. IP68 and above is required.
