My real world UNVR-Instant capacity experience and moving to a UNVR-G2.
First, why are the Flair options so horrible? I couldn't find one that would suit. Is this something the mods can fix?
Over the last 6 months I'd been using a UNVR-Instant and posting about how I'd gone way beyond their recommendations for cameras and it was working great. I'd even posted asking people what I should be looking at to find deficiencies. I was running well over double their recommendation and I was finding performance of video playback, etc to be just fine. I was using a 12 TB WD Purple Pro drive.
When the UNVR-G2 came out I was interested in it for the extra AI features but at first didn't see enough reason to buy one. Finding out that the early ones were coming with 16 GB of RAM instead of 8 GB seemed like a deal and I love a deal. So after waiting weeks for stock to become available I bought one (and got the 16 GB) and have been running it for nearly a week now. I also couldn't find anybody that could give me real world experience of moving from the Instant to a G2 so I decided to find out for myself and share.
I had been having problems with my G6 PTZ cameras failing to respond to PTZ commands or just behaving erratically. E.g. a tap to move caused the camera to keep going until it hit the limit. I've been working with UI to debug this but so far I've mainly only gotta possible reasons but no clear answer. One thing that did come up was the overloaded UNVR-Instant could be the problem but I'm still waiting on an answer as to why. I have a feeling that the PTZ commands to start and to stop are managed by the UNVR instead of by the camera, so if the UNVR is busy it may not send the stop command. But that's just a theory.
Since moving most of my cameras to the UNVR G2 the erratic movements have stopped BUT there has also been firmware updates, one mentioning addressing some PTZ issues. I still do have G6 PTZs that just stop responding to PTZ commands. Rebooting ether the camera or the NVR will fix this for a while.
So, I wanted to come back here and post my experience and let people know that although it seems OK to overload the UNVR-Instant by a factor of two, you might want to avoid doing so if you have PTZ cameras. Beyond that I saw no other problems that were unique to the UNVR-Instant.
Now on to some other experience differences between the 2 UVNRs. Other than the AI features, there's not much to speak of. Certainly the UNVR-G2 is specced for 5X the number of cameras, it has a lot more RAM and CPU power, capacity for 4 drives, but I'm really not seeing any user experience performance differences between the 2 UNVRs at this time. There will be a point where the G2 will handle more cameras than the Instant, but even with 16 cameras the Instant was doing well. I truly believe the UNVR-Instant is a great NVR and for many it is all we need. Don't discount it because of the low recommended camera count or because it looks like consumer grade gear, it's likely capable of more than you expect. I'm still running mine.
BTW, that deal of getting more RAM? Well, so far my UVNR-G2 is only using 5 GB so an 8 GB model would be fine for me and the extra 8 to get 16 GB buys me nothing so far.
