The video image of the smart camera may appear black and white reversed for the following reasons:

Insufficient light: If the scene is not bright enough, the camera may automatically switch to black and white mode to improve the brightness and clarity of the image

Infrared night vision function turned on: The infrared night vision function of the smart camera can provide better image quality in low light conditions, but it will cause the image to become black and white

Photosensor blocked: If the photosensor of the camera is blocked, it will also cause the image to become black and white

Camera failure: If the camera's image has a fault, where the color storage and transmission have problems, or the camera and camera aging, may also cause the color to become black and white

The solutions are as follows:

Insufficient light: Increase the light in the scene, or adjust the position of the camera so that it can receive more light.

Infrared night vision function turned on: Turn off the infrared night vision function, or adjust the brightness of the infrared night vision lamp.

Photosensor blocked: Clean the photosensor of the camera, or adjust the position of the camera so that it can receive light normally.

Camera failure: Replace the camera or camera, or contact after-sales service for repair.
