Has anyone seen a router overloaded by cameras?

topgeek · Jun 18, 2017

I have 10 Hikvision IP cameras (3 & 4 megapixel) and I think my issue is the router cannot handle the workload?

If I turn off Blue Iris the network stays up solid - no problem.

If I turn on the cameras - every few minutes something trips and the network goes down for 10-20 seconds and then comes back online.

I've tried two different routers (an actiontec and a cisco - admittedly both older units) and it happens with either one. Everything is static IP and DHCP is disabled. uPNP disabled.

Has anyone else seen this issue?

Does anyone have a recommendation on a router that is powerful enough to handle the 50+mb/s of camera traffic plus all of my servers, miners & stuff?

Because it's happening with two different routers I wouldn't think it's a router issue. I would be tempted to fire up wireshark and see if it gives you any hints as to what's going on. When you say the network goes down, what does that mean, are the lan card lights still on? Is there nothing in the router logs?

are you using wifi or wired?
if wired, connect the blue iris pc to the same switch as the cameras and no traffic will pass through the router...
if wifi stop using wifi.

Everything is wired gigabit.

Cameras are all over the place so some things go through a few switches before getting to the Blue Iris server. Everything is on its own static IP address network.
Infrastructure needs from one building to another dictate the need for other traffic to go through the same line so I can't isolate the camera network completely.

By going down what I mean is:
All computers and miners suddenly see the network as offline (no web access, RDP connections disconnect, miners can't get shares, etc) for about a count of 20 and then everything comes back online and everything works normally again. This happens over and over every few minutes.

In the past, there was one router- the actiontec and it was our DSL modem. It would literally crash and reboot itself over and over if blue iris and all the cameras were running (and it got really hot so I think it wasn't up to the traffic) - so I added another router for the blue-iris camera network and that stopped the DSL modem from crashing... but since then the network has grown a bunch - and it kinda feels like that again - which is why I wonder if this Cisco isn't up to the traffic).

If I turn off blue iris - the network is solid - never goes down.

The routers are piece of crap - so they don't have any logging or anything (best buy residential level stuff).
I've tried running wireshark but the huge amount of traffic has my brain overwhelmed - I'm not smart enough to understand what is an issue and what isn't...

10 cameras cannot come close to saturating a gigabit network...make sure pull point subscription is disabled in video settings in bi for each camera... check logs for erros

p.s. the camera traffic is over 50 megs/second - which is why I wonder if it is the lousy cheap router overheating and crapping out.

Thanks for tip on "pull point subscription" - will do!

I would do what Fenderman suggested in his first response -- buy a cheap gigE switch off Amazon and isolate your cameras on it, rather than run your camera traffic through your router.

Have you changed the firmware on your router(s) to DD-WRT?
