Hello,

I have (3) 4MP cameras along with (5) 2MP cameras. These IP cameras use H.264 compression.

I have all (8) cameras wired into a BV-Tech 8 port POE switch. https://www.amazon.com/BV-Tech-Port-Switch-Ports-Uplink/dp/B005GAATOG/ref=sr_1_3?ie=UTF8&qid=1517757535&sr=8-3&keywords=bv+tech+8+port+poe+switch

I have the switch connected to a gigabit router. All cabling is cat5e.

My PC based recorder has an AMD 8-core CPU @ 3.2GHZ and 16GB of RAM.

When I add the cameras to ispy connect or blue iris software I get lagging video. The frame rate goes to 2-3fps on all cameras. My computer hardware seems to be suitable as the cpu doesnt go over 50% and 40% on ram.

I thought the problem may be the POE switch because it is 10/100mbps and not 1000mbps but bandwidth calculators say the cameras stream at 8mbps per camera. That is 64mbps max.

Why is my frame rate reduced?

Replace the patch cable from your switch to the BI cpu and see what happens.

Don't trust a bandwidth calculator you found online to tell you what your cameras are streaming. That is controlled by the bit rate setting in the camera's web interface and/or by the quality setting if doing VBR encoding. Bandwidth calculators know nothing. You should check the network usage in Task Manager.

You should try disabling some of the cameras to see if the rest of them behave normally when some are disabled.

Another thing you might try is reducing the frame rates (configured in the camera's web interface) to like 10 FPS each to see if that is stable, and increasing it from there.

This is my first post here, I am also having the same issues with BI. I am running an i7-3770k with 16gb RAM, although all of my cameras are wireless. I have 10 Wansview HW00043 cameras. I tried hardwiring them as well since they have that option, but saw no improvement. My CPU and RAM usage are both under 40%, network usage is under 12mb max. I set all of my framerates to 10 fps, tried only one camera, and tried every IP cam software I could find. I did find that Contacam worked flawlessly until about 30 mins of use and then it started having the same issues. One thing to mention is that the Contacam bitrates were significantly higher (up to 2mb vs up to 200kb in BI). I ended up switching back to BI, and it seemed to work ok for a few but then went right back to lagging. Webview is just as laggy.

At first I thought it was just the cheap cameras, but what I noticed is that they all seem to lag at the same time, and my framerates are all pretty consistent. This leads me to believe that it is NOT the cameras. It's almost seems as if my GPU is heating up after a short time and causing the lag. Task manager shows no spikes in any of the loads. I'm at a loss. I hope someone figures this out.

Your router or switch might be getting hot. That will slow things down. Put a fan on it, see what happens.

Likely the router...wire up cameras and connect bi to the same switch...
Wansview is garbage.. avoid at all costs...
