Well, it's not in a set pattern, we usually have the two outside cameras criss-crossing our parking lot...that way we can control when we are in the office w/out doing the presets. It's mainly to try and catch folks breaking into cards.
Now for the most part, I have just tried turning the server on and off, and disabling the camera and enabling the camera in the system as well...but I haven't figured out how to power down the camera itself w/out going up on the roof to do that.....I just googled tips and it didn't really give me a lot of information, but the information they did give, I tried to no avail.
