When it's on, it's on. There's no timeout or momentary power mode. It has a tripod mount and video out, so it's probably that way for setting up as a surveillance camera. Having the power time out wouldn't work there.

I have a TV monitor in a box. I built it years ago for setting up security cameras in jails and the like. (It's a helluva lot faster/easier than yo-yoing back to the control room) It's self contained with a battery pack, and has a 7'' color monitor and video in/out jacks. I built it into a small aluminum tool box. It works great with the night scope.

Since it's a CMOS camera, I doubt it'll degrade like the old type night scopes.
