Using all dahua turret cams, image quality is awesome, rig is running sub 20% utilization all the time. My issue is that the sensitivity/contrast settings that work by day give me a LOT of false positives by night because of headlight wash on the street in front of my house. Daytime, I want to record the sidewalk, nighttime, just my porch---no wash on there. I can't, for the life of me, figure out how to make this happen. Is it possible? Setup: Zone A: all of everything I ever want to monitor Zone B: just the porch deck area and in a little bit, takes a pic and sends me a text. Someone is ON THE PORCH. Zone C: what I WOULD monitor over night---just the whole porch. No schedule in place, I never want it to NOT monitor. Is it possible to configure zone by time? Pics available if they'll help. Thanks!! Also: network receive buffer, is this kept in RAM? I'm sitting on 16 Gigs in this machine and can't make BI use more than 2 no matter what I do.
