This blurry image error is quite common on dome cameras, mainly due to the rubber seal not being placed close to the image surface, causing infrared reflection at night, affecting the image. image quality.
In addition, if the direction of the infrared light is not adjusted properly, operating in a high-temperature environment, the rubber seal shrinks are also the main causes of this error.
