Camera has auto brightness issue at night

One of my cameras keeps trying to adjust brightness in night mode and keeps triggering the motion detection. It just constantly records. It may be the Gain of the image sensor. it appears to fluctuate in a regular pattern all night long.

Hi, please kindly check the sensitivity settings of the motion detection, you can try to set it lower. Refer to How to Set Motion Detection Sensitivity of the IP Camera
If it doesn't work, please provide the firmware version of your camera and try to upgrade it to the latest version.

Still triggers with the sensitivity all the way up to 50.
I have experimented with the advanced settings for the manual exposure and can see the gain of the image is not constant. This causes the image to go from dark to bright and triggers the motion detection every couple of seconds.

Hi, if it is possible please send the video file you record on your camera to support04@reolink.com and we will check it for you. Also please kindly confirm the firmware of your camera is the latest and send the screenshot of your advanced settings configuration.
