Hey, long time reader first time poster here.

As the title suggests, I recently set up 4 IP Cameras in our house that are accessible remotely from anywhere with an internet connection using DynDNS/Port Forwarding.

The cameras themselves are working perfectly as intended, but whenever they are on and connected to our home-network every computer in the house seems to have between 5-10% packet loss which is incredibly annoying, especially since I play a lot of online games.

If I turn the cameras off or deny them access to the router, the packet loss goes back to 0% instantly.

So, has anyone got any idea how to resolve this, without having to deactivate the cameras?

Additional info:
ISP: Telenor (Norway)
Router: Thomson ST780
Bandwidth: 16 Down, 1 Up

Also, according to pingtest.net;
Average without the cameras:
Ping: 10
Jitter: 0-1
Packet loss: 0%

Average with the cameras:
Ping: 40-50
Jitter: 10-20
Packet loss: 5-10%

Thanks in advance for any assistance.

Are you doing offsite video storage?

No, it's not being stored anywhere. You can only view the footage in real-time.

I can't tell you why that's happening. But considering the why is much less important then the fix I'd suggest segmenting your IP camera traffic on your home network from your normal traffic.. In other words, put it on a different network isolated from your home network..

Are you using wireless? Are the cameras using wireless?

The cameras are, I'm not. Regardless, the packet loss happens both with wireless and cable.

Run and upload test with your cameras online. I would be willing to bet you are running out of bandwidth for upload. Depending on how high the resolution is the frame can range from 10KB to 140KB that is per frame then do the math once you add in your frame rate then you also have 4 of these going. You might find this article helpful to determine or cut down some of your bandwidth requirements. http://http://www.imakenews.com/kin2....cfm?x=b11,0,w

I can't see much difference in my Upload speed with the cameras online. The only difference is packet loss, and as a result of that, ping.

Sorry for the late post, but I wanted to wait until a bit later on the day to confirm a suspicion before trying anything else.

The suspicion was that the problem only happens early on in the day, and after 17:00ish the packet loss is gone, even with the cameras on. It seems that this is the case, or at least it has been for the past 3 days. Does this mean my ISP is at fault or?

If your cameras are not uploading anything to the internet, it's not the cause. The only thing it "could" be doing is overwhelming your wifi network at home. If you plan on continuing to use them in wifi-mode you really should isolate them onto their own broadcast domain (network).

What? You're suggesting a group of infected computers are probing his IP cameras which in turn would be causing his WAN connection to experience higher then average latency and jitter?

If the cameras themselves are not uploading any data and only streaming their UDP feeds to a monitoring device on his LAN then his overall WAN connection issue is being caused by something taking up resources on either his router, or somewhere out in lala land in the great white cloud.

What kind of cameras do you have?
Are they on their own subnet?
Do you get the same behavior with only one or two on?

What is the Duplex setting set to? That is usually the biggest routing issue I see; frequently our switches will be set to "auto negotiation" while the client causing issues with be set to "full" or or "half". This kind of duplex mismatch can be quite a pain, and unless you are using a managed switch, you will not get any kind of warning.

Set them all to "Auto negotiation"

Not sure what the issue was but managed to fix it. I just reset all the cameras/router to factory defaults and set it up again from scratch.

Didn't exactly know how to set them up the first time so I tried a lot of different things, and probably left some bad settings behind.

Regardless, it all works now and with 0% packet loss. Thanks for all the input though, greatly appreciated.
