NVR Sluggish...too many cameras?

We have a Unifi 2TB NVR with about 14 cameras.

 

We're finding that the unit seems very sluggish, particularly viewing one of the cameras in livestream.

 

The network we are on has ample capacity, so we don't think it is a network problem. But the images pixelate and are jerky. This wasn't the case when we had fewer units.

 

Is there any solution OTHER than purchasing a seperate computer and migrating to a non-NVR appliance solution?

 

Anything else likely to be making images in livestream refresh slowly and not pixelate?

Re: NVR Sluggish...too many cameras?

Hi @SeattleDavid,

Are you seeing this while viewing multiple cameras only, or does it do it as well when viewing a single live stream?

Just to confirm, are you using the latest version of Chrome with HW Acceleration enabled (default state)? Is the NVR running UniFi Video v3.9.7?

Re: NVR Sluggish...too many cameras?

1) Recording option is set to "Motion".

 

2) The primary sluggishness is in these cases:

 

-When you click on a camera for Live View it can take a very long time for the video to start. There are three sequencing dots in the lower right corner that chase each other for minutes.

 

-When watching a recording, if you move the slider to the middle of the video (to skip forward) from within the IOS application (connected to the same LAN as the NVR) you can wait minutes for it to start.

 

There are 14 cameras connected...10 G3-Pro, 2 G3 Dome, and 2 G3 Flex. It is the 2TB version of the Unifi NVR.

 

Everything is on the latest firmware/software.

Re: NVR Sluggish...too many cameras?

The problems primarially happen when:

  1. Using an IOS device and the Video app, when watching a recording and skipping ahead. Or,
  2. Using Chrome when watching a video and skipping ahead in the video.
  3. In Chrome when attemnpting to view a live stream.

 

The main symptom is that the three sequencing dots in the lower right corner sequence for minutes. Basically, seeking ahead in a recording is reliably very slow. (It can take 3~5 minutes to begin playback.) Starting up a stream is often very slow.

 

The problem is much less about breaking up and pixelating during active playback.

I am the least knowledgable person on this forum and should not be posting, but just for comparison... we have 20 cams using the same NVR you have and we see no latency on our p2p network.  Recording is set to motion on all but 3 cams and most are set to hi-rez. We typically set the Seconds to Record for both before and after to 5 seconds.

 

On 1 PC, we have Live View up and running 24/7 for all 20 cams. Again, no real latency.

Re: NVR Sluggish...too many cameras?

The UniFi NVR is a simple appliance with low-end hardware. It's not meant for so many simultaneous 1080p streaming cameras.

 

I would find a PC you have lying around that was made within the last 5-7 years, add more RAM to it, and migrate. The migration process really is not that difficult and simply involves following instructions.

 

This forum post's solution has pretty good steps on how to migrate: https://community.ubnt.com/t5/UniFi-Video/Move-NVR-from-old-server-to-new/td-p/1806092

 

Good luck!

Re: NVR Sluggish...too many cameras?

<Sigh>

 

Before purchasing these cameras and NVR I went to these forums and asked how many cameras was a reasonable number for the device. I was told 20 was a safe and reasonable number.

 

I specifically mentioned that I DID NOT want a PC which would require maintenance, require loading Java (a prohibited runtime in our environment) etc.

 

An Appliance computer such as the NVR is low maintenance. That is why we chose to go that way.

@SeattleDavid,

 

Please open a ticket with us at support@ubnt.com and include your NVR support file, so we can review the logs and diagnose further.  A description of your network between the client (system running Chrome) and the NVR would be useful as well.  Including a link to this thread will be helpful for context.  Thanks!
