But you would be OK leaving an NVR on 24/7?
Do as most of us and don't have BI on your main computer and treat it as an NVR and only do BI on a different computer. Buying another computer would be cheaper than an NVR.
Enough people have shown a newer computer uses less power than an NVR.
One doesn't surf the internet or check email on an NVR, so why should this VMS be any different.
BI wouldn't be able to playback any video not processed by BI if you had BI off and video going somewhere else.
You could put SD cards in the camera and do that instead, but they will only record if they are on lol.
