Hey Guys, We just installed two of these near entrances to an apartment complex. At first the camera was in indoor mode so we changed that to display a beautiful picture during the day. the problem that I am having now is that the camera does not switch into night mode when it gets dark outside. The picture just goes black as it gets dark. The onlysetting that we changed from the default setting was indoor mode to ourdoor mode. Can you help me with these please?
