What I found was that maybe once or twice a week, a camera main stream resolution had been reconfigured down to 1080p. I added most but not all cameras to QVR Pro, configured to do event recording via Stream 1 only.

I thought it might be interesting to set up QVR Pro to do the event recording, with the possibility of retiring the NVR that does this currently. The cameras are a mixture of 8MP, 4MP and 2MP low-light cameras. I have a stable 9-camera CCTV setup with one Hikvision NVR doing continuous recording, and another doing event-only recording. This is a 'behind the scenes action' that there is no control for, and unfortunately meant that QVR Pro was not a viable addition to a setup where an NVR also records from the same set of cameras.Ī pity, because QVR Pro has developed quite nicely from it's original rather bare beginnings, and supports a good set of the smart capabilities that current-generations cameras provide.Ĭlick to expand.That's how the camera settings in QVR Pro were configured. So QVR Pro is reacting to an apparent transient loss of signal by reconfiguring the camera video to a lower resolution and leaving it there. No such events occur in the NVRs, the camera connections are 100% stable. What i found was that sporadically, every week or so, a random camera's video settings would have changed, dropped down to a lower resolution.Ĭross-checking the QVR Pro logs, these changes occurred when QVR Pro decided there has been a transient loss of video or camera disconnection event. I have another NVR that records all the same cameras continuously. Of my nine cameras, I let Blue Iris do motion detection on six them of them, and BI monitors the built-in motion detect of three of them (two of which have the AI features built in, and one had a PIR sensor built in).Īlthough I'm on Blue Iris now, I started with Surveillance Station on my Synology NAS and also had a few months of using a Dahua NVR in between.Ī couple of months back I thought I'd try using QVR Pro as a potential replacement for the NVR that I use to record only events, as the NAS has plenty of availablity and capacity to run it. If you go with a PC-based VMS (like Blue Iris, Sighthound, Milestone, etc), since they run on boxes with more processing power than most NAS/NVR setups, their built-in motion detection often has features more advanced than a camera's basic motion detection. For that reason, I'd really really really suggest keeping Dahua/Hik's advanced motion detection in mind when building out a surveillance system. Dahua and Hikvision are the brands that seem to get the newest low-light camera tech and it tends to stay with them exclusively until something better comes along, then the older stufft may trickle down to consumer brands like Amcrest, Lorex, etc. If you're going to be using outdoor cameras and you need ones that work the best in low-light, chances are high that you'll land on a Dahua Starlight+ or Hikvision Dark Fighter model. IVS/Smart Events helps reduce false alerts with a much less risk of missing real motion. The general issue with basic motion detection is that if you start getting a lot of false alerts you only have two options to tweak (sensitivity and threshold), and the usual conundrum is that once you tweak them to avoid the false alerts they're often set so low that they start missing real motion. If QVR Pro limits you to only using the camera's basic built-in motion detection, here's what you get to work with:

Here's an example of some of the IVS motion detection abilities built into newer Dahua 'AI' series cameras: Their newest cameras are starting to coming with "AI" filters that will only trigger alarms if a vehicle and/or person is detected. Smart Events/IVS can significantly reduce false motion alarms. This is worth verifying, but it does NOT look like QVR Pro supports the separate advanced motion detection features built into Hikvision (called Smart Events) or Dahua (called IVS) cameras. So looks like if you're going to have more than two cameras, you'll be using the camera's built-in motion detection on at least some of them. The video mentions that if QVR Pro does the motion detection itself that it's limited to two cameras, presumably because of the load it would put on the processor.
it can either use a camera's built-in motion detection or QVR Pro can do motion detection itself. It looks like QVR Pro handles motion detection the same way that Synology's Surveillance System app does.

I was curious how QVR Pro handled motion detection so I watched the "QNP351 - QVR Pro Guide - How to Setup Motion Detection" video on the link you posted above. Click to expand.Motion detection is a frequent reason folks will "abandon ship" and jump from one surveillance system to another.
