I think I would agree with Customer that this could be a power problem. The bottom video is clearly in daytime mode (it’s in color), and top video appears to be in night mode (it’s in black and white). Assuming that the camera is turning on the IR illumination when in night mode, that will increase the power consumption. If you are having a lack of power issue, having the IR illuminators turned on will certainly make that worse. As a test, go into the Settings > Advanced Settings > Night Vision Mode > Night Vision IR lights. Set the IR lights to Off. Note that you have to have the Night Vision Mode to Auto or On in order to set the IR lights setting. What all that will do is prevent the IR illuminators from coming on when the camera goes into night mode.
How are you powering the camera?
