High Latency Issues

[Lowvoltetech]

Hello everyone, I am having a head scratcher here and was hoping you could help out.

I work for a local grocery chain in my area as their camera/IT installer. I am installing UNV products throughout the locations but im coming into an issue. Some locations appear to not work the way they should. Every time I remote view, or turn on the port that the NVR is plugged into the Store network latency will increase tenfold and bring the store down. I think it maybe due to Upload speeds but if you have any other suggestions i would appreciate it so far this has happened in two locations. I don't know if there is a way to throttle the connection or if i just need to increase the upload speed.

What's the upload upload speed of their WAN? I'm unfamiliar with those cameras but I'd first start by knocking down their resolution/fps and see if the connection is stable when remote viewing on a lower resolution.

Large stores/chains may maintain a high availability connection to their backend POS/Inventory databases off site. Those dedicated connections may not be super fast and a couple 4k cameras set at 30fps with little to no compression could choke the upstream bandwidth.

So each store is different, usually 10-20 upload. I would say that would be the issue but one of the stores has a new XVR but till using the 1.8mp analog cameras with 20 upload and will still do the exact same thing. I don't have specifics cause I am not the IT engineer

I understand that you are the grocery chain's camera/IT installer but I was wondering: In addition to the above considerations mentioned by @biggen , are there any PCI-compliance issues introduced by connecting an NVR with Internet access to the store's network where credit/debit cards are used for purchases? Or is the NVR on it's own VLAN?

10 - 20 Mbps is basically peanuts. Just one of my 4MP cams streams a constant bit rate of 8Mbps to Blue Iris. You will probably need to find a way to compress that video for offsite viewing. Usually, the NVR solution will have that ability so you don't have to view the native stream of the camera itself.
