The video of the conference camera turned black and white because of smearing.
The video conference camera chip used is a chip that changes from color to black. During the day, when the light is sufficient, the video conference camera will take all color pictures. At night or when the light is insufficient, such as cloudy days, it will automatically switch to the mode of turning on the infrared light, and then the chip will become black and white, and the picture will naturally become black and white.
Video conference camera image failure, including color storage and transmission problems, or camera and camera aging, may lead to color change to black and white.
The monitored video line has poor contact, that is to say, the circuit receiving the image signal in the video has virtual welding.
The photosensitive part of the camera is generally a passive photosensitive resistor or diode on the lamp board. If it is blocked, it is easy to feel no light, which leads to turning the camera on in black and white.
