Hello all, Long time reader, but never posted anything. a couple of weeks ago I pulled the trigger on a Dahua NVR5216-4KS2 and a couple of 4MP Dahua bullet cameras. The IPCamTalk Cliff Notes were extremely helpful in making this decision, thanks! I've set it up and the whole setup has been working ok so far as far as recording video goes. That part works out of the box. However, any kind of motion detection/alarm stuff is unbelievably unreliable. I'll try to list em out, hopefully someone can give me a hint on what I'm doing wrong here. 1. If I go to playback tab in smartPSS, I never see anything apart from general recording. There has never been any motion detection recording, despite me getting multiple motion alerts over the past three weeks. The event settings seem to indicate that it should record the respective channel with a delay of 10 sec (not sure what that means) 2. Some of the non Dahua IP cameras dont get the four regions, just a single region. No matter what region I set up with whatever sensitivity and threshold, I've never got a motion alert from these cameras. 3. Speaking of regions, what are they for? Should I paint the entire regioin of interest with one of the colors, i'e' red, green, yellow or blue? Or is the unpainted part being monitored for motion detection. 3. While setting up motion detection zones, the software repeatedly forgets my sensitivity, threshold and zone settings. I've tried all ways of configuring I know, i'e directly on NVR with mouse, Web and SmartPSS on PC and Mac. 4. Dahua cams get Sensitivity from 0-100 and also threshold setting + four regions. The HikVision cams only get sensitivity 1-6, no threshold setting. 5. The channel name and time overlay only works of Dahua cameras, is this expected behavior? If all you need is recording, yes it does the job, but all the other fancy advertised features are unusable for me. God, I can only imagine, how good the software on something like a UniFi Video NVR would be. I've been having thoughts of ditching this NVR and going for a Windows box running BI, is it too soon to go that route?
