Hi Guys,

 

Am trying to plan a IP CCTV install for our new office, the problem is bandwidth. We are going to have 32 cameras that my boss wants running at 1080p with at lest 15fps.

 

Our new office is going to be wired in CAT7 everywhere. We will be using gigabit network equipment (switches, routers, and so on), I would like to use 10 gigabit but no one in the UK goes beyond CAT6a.

 

Using the cameras manufactures bandwidth calculator the cameras are going to be pulling around 580mb/s this is obviously going to put a lot of strain on the network.

 

Is there a way you can setup two network (one for CCTV and one for general use) but with the CCTV NVR accessible from both so that recorded and live footage can be viewed from a computer on the network?

 

Sorry for the long post hated to try and give you as much info as I can.

 

Thanks for any help you can give and wanted to say Thanks to Fr. Robert Ballecer, SJ and Bryan Burnett for a great show.

Use a dedicated switch for your CCTV, IMO it should be separate from your data network anyway. If you have multiple floors make sure your switches have 10G uplinks.?

 

For viewing access, setup the NVR and monitoring PC on this segment. Although people will tell you to use dual NIC's,Do not put dual NIC's in the monitoring PC and ride both network. This is not best practice.?

580 Mbps is pretty near the real-world experience of Gigabit ethernet. Is that per camera or for all 32?

[G+_Ben Reese]

And, yes... You'll definitely want to segregate them to their own switch - both for the QOS of the cameras and to reduce congestion on the rest of the network.

Hi Guys,

Thanks for all your comments and advice, 580Mbps is for all 32 cameras running at 1080p 30fps, however this will go down a bit as we only need them to run at 15fps.

 

When you say a dedicated switch do I also need a dedicated router and just make a completely separate network for each or can they share the same router.

 

Thanks again for all your help

Good. I thought that seemed a bit much per camera... Just a separate switch should be fine if the server storing that video is on the same switch. If the switch is working correctly, it should keep that traffic from drifting out into the rest of the network.

Fantastic thank-you. I'm looking into using a Level 2 Managed switch probably a Draytek P-2261, would this be a good choice or would their be something better you would recommend?

[G+_Ben Reese]

I'm not sure but it looks like a good option to me. I'm far from an expert on switches. 22+ POE ports would be good for cameras and it sounds like it's designed with cameras in mind - though that may not be necessary for your setup. I couldn't find anywhere in the specs about what the maximum data capacity is, but I'm sure it's far above what the cameras will be producing.
