How to configure IP CCTV Network

Hi,
Please check the attached network to be configured,

Select any IP range to the cameras/switches.

I need detailed configuration for Switches, specially the Core switch.

If you need to modify minor changes in hardware, no problem.

Regards. IP CCTV Network

Nice setup.

With that many cameras (170) you should setup a VLAN for the camers. You should set each camera to a given IP address and port in relation to the VLAN you setup.  

Each switch should be setup to pass the IP addres (of the camera and or port)  to you respective gateway.  

You are going to have to know Cisco in order to set this up.  Good Luck.

Hi,

I know Cisco.
Each camera will be given a specific IP, then why I need VLAN ?
I cannot connect them directly to Switch without VLAN?
How about the Gigabit interface configurations between switches?

ANOTHER QUESTION: WILL IT DIFFER (CONFIGURATION) IF I WANT TO USE POE?

farhatwael,

You do not want to have a flat network with that many devices, especially if you decide to grow. It is just not a very scalable solution; The 2950s dot not support POE (Power Over Ethernet); you will need to get the 2960, 3750 or some other switch that supports POE ;

Cisco Catalyst 3750V2-24PS
WS-C2960-24PC-L (Being cheaper than the 3750)

I agree with rfc1180.  You don't want a flat network.  A VLAN is a great solution for this type of installation. Since broadcast frames are targeted and processed by all devices, creating smaller domains can reduce overhead and limit resource utilization. Only those workstations in need of receiving specific broadcast or multicast traffic can exist on the domain, preventing other devices from receiving unnecessary traffic. The use of VLANs to create broadcast domains also eliminates the need for routers to handle this function, permitting operation at lower latencies compared to routers under heavy load.

Now maybe I misunderstood your question in full.  If this is a dedicated network for the cameras only. Then a flat network may be ok.  If you have other devices on the network like multiple computers, printers and office equipment, then a VLAN is the best option for setup.  I would even consider multiple VLANS depending on cctv zones and DVR units you are using.

Yes, you can use POE with your existing equipment but you will have to get POE injectors. For that many cameras, you are talking alot of rack space and additional equipment purchase.  I too suggest that you move to a switch that supports POE without all the additional equipment and patch cables.

Really appreciate your answers,

fixitnick: this is a dedicated network for the cameras CCTV, on the network there's only one or two workstations to view and control the cameras. so i think flat network may be ok as u said.

now what i really want regardless the switches type (consider the appropriate switch type is used) is the main configuration between switches and between the switch and the end user.

how the switches will communicate in terms on configuration commands!
(with examples please)

Thanks again for your replies .

Sorry for that, it's readable.... studying and testing ....
I'll Revert back soon .. thanks :)

Thanks RFC, i didn't check it on the switch, but the configuration makes sense and got good idea about how to configure the network :). thanks

I too have a large IP CCTV system with over 600 GarrettCom switches connected by fiber optics.  It is all layer 2 right now and all flowing back to a Cisco root switch.  I have about 200 IP cameras on one VLAN setup just for them, with other VLANS for other types of equipment plugged into the other ports on the switches. I do have latency, and I'm wondering what other things may help with that. IGMP, QOS, etc.

Have you checked you network ? latency may mean that network is congested. what is the type if the cameras you are using ? are they megapixel ? what is the throughput of each of the cameras ? are you using fiber from cameras to switches as well ?
