The camera may have different reasons for flickering, blurring, and noise, so the solutions are not the same. Here are some common reasons and solutions:
Insufficient light: If the scene is not bright enough, the camera will automatically switch to black and white mode to improve the brightness and clarity of the image. Increasing the light in the scene, or adjusting the position of the camera so that it can receive more light, can alleviate this problem.
Lens contamination: If the lens of the camera is contaminated, it will also cause the image to become blurry. Cleaning the lens of the camera, or replacing the lens, can solve this problem.
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 image to become blurry or noisy. Replace the camera or camera, or contact after-sales service for repair.
