New to IP

Looking to install some ip cameras. Initially 12, but customer wants a 32way recording NVR for the future.

 

Not having used IP cameras before, I am a little concerned with upto 32 cameras? Even if I install a dedicated network for the cameras, is 32 not going to bog down the Ethernet connection to the NVR?

 

How many cameras at good high res/frame rate are good for 10/100 link, or gigabit link?

 

My initial 12 will be connected to two poe switches due to site layout, and was planning on these two switches going back to one switch, and then the NVR?

 

Sorry, complete IP cam newbie!

We use a 24 port Netgear ProSafe PoE switch with 2 Gigabit ports. The NVR PC can connect directly to the switch on one of the Gigabit ports, the other port can go to their normal Gigabit network.

 

You start losing switch efficiency when you break it up into multiple switches. Makes sure the PoE switches you buy have gigabit ports (or all gigabit) and feed into a common gigabit switch.

 

Since your switches will be distributed, get all managed switches, at least you can check on switch problems or camera problems from a browser anywhere on the net.

Thanks.

 

I was thinking of using two of these:

 

http://www.misco.co.uk/product/127264/NETGEAR-PROSAFE-24-PORT-POE-10-100-SMART-SWITCH-WITH-4-GIGABIT-PORTS

 

It states four gigabit ports, but then states 2xgigabit and 2xSFP ports? It also states 100mb switching - does this mean it wont make use of 1000mb on the gigabit ports?

 

I would want three gigabit for NVR, camera switch uplink to other side of warehouse, and gigabit link to existing network.

 

Cheers.

Yes, that's the switch we use. The SFS port is a gigabit fiber optic port, you likely won't be using that but instead use the Ethernet gigabit port. Like I said, it's really 2 gigabit ports, one for your NVR and the other to your regular network.

get two nic cards in the server that way you can isolate the traffic from the cameras to the server and only have the traffic from the server out on the common network

I had thought that, but some NVRs don't have facility for two NICs. Which make do you recommend?

He meant if you use a PC as an NVR.

I guess.

 

Although, have seen some NVRs with dual NICs.
