I have a 16 channel, 1 TB DVR, 8 camera Q-See setup with 600 line cameras. I'm still figuring the system out, so can't really rate a lot of it yet. It records on motion and daylight resolution is pretty good - facial recognition at night time is maybe 50-70 feet at best as far as I can tell. I haven't played with any of the settings or changed anything from the defaults though, so I'm not sure if I am on the highest resolution or not. I just hooked it all up and haven't really given it the time to mess with it.
