Looks like they're coming out with a new version.
I have two Dahua nvrs with wireless mice. One with the dongle on the front port, the other on the rear port. Plug and play, no re-boot necessary.
Yeah, should be something like this
Don't see why not..
EDIT....Note that the tilt is only 55 degrees. Straight down would be 90 I think.
Wall mounted: 195.3mm×90mm×102.7mm (7.69""×3.54""×4.04"")
Ceiling mounted: 190.8mm×90mm×112.2mm (7.51""×3.54""×4.12"")
Only 63.71 lbs.......
I've had 22 cams connected to my 5232-non poe- . Even at high bit rates the nvr can handle them fine as long as you use a gigabit switch.
I think aristobrat's explanation of low light specs is as good as it gets. One thing I might suggest is to just get one 2831t at first and try it...
"Note the green light that fenderman posted about in the pics below. Haven't found a way to turn that off yet..."
Narrow strip of black electrical...
Have you tried setting up the cam's ivs on the nvr? How are you viewing the nvr? directly or the web interface?
