Hi all!

I am setting up a new subnet for our ip security camera system and I am looking for suggestions on what type of switch I should be using and any specific switch recommendations.

All the cameras are going to be high mega pixel cameras (probably 16 cameras), and hopefully POE, so the switch will have to handle POE.

Thanks!

Jp.

I would go with Cisco 3750's,  I would also recommend putting the cameras in their own VLAN to segment them from your data network.

Make sure that the POE cameras will be compatible with the version of POE (correct wattage) of the switches.

Hope that helps.

Good point.  I will have to check the POE versions.

Any switch recommendations closer to the $1000 mark?  We are only going to have about 16 cameras and although my budget is decent, the Cisco 3750's may push me over.

Thanks.

The 3750's would certainly push you over, we buy ours 'experienced' and we pay around 2k-2500.

I know that Netgear has a PoE switch, as I think Linksys may as well, however make sure that they are managed and can handle the layer2 VLAN config you desire.  Another possible solution would to get a non-managed PoE switch and vlan it out with an exisisting intelegent switch?  I dont know what your environment looks like, but if you have a switch in place which you can configure VLANs, you could simply configure the uplink port on the mananged switch to set the default VLAN to the vlan ID of the security camera VLAN.

Looks like this might be one to consider, this one can do the VLANing you want to do as well.

Honestly though, while I like Netgear, it has its place.  I would take into consideration the environment its going in.  Could this implementation afford downtime without significant loss of profits/producivity/security?  If this system is going to watch over an environment where the assets are costly, I would seriously push for Cisco.

Hope that helps.

Well, I do have a 3com X5 that can do VLANs and my networks here will all be running back to that anyway to access the WAN.  I just have to figure out how to configure the thing to my network first....but that will be another post.

With that being said, would the managed switch be necessary? This implemenation can also afford a bit of downtime if it were to occur (and it does the odd time, I can deal with that as it can't get much worse then what we have existing).  My main goal is performance, we don't have the greatest performance right now (trying to change things to improve that) and I don't want to make it worse.

Here is a glimpse of our network looks like (which is under works right now).

Why do you have a 10mb wireless bridge if you have a connection over the internet?  

For network performance/ troubleshooting use some good free tools, I use The Dude, Cacti, and Nagios.

They are great, The Dude will help you pinpoint nodes or points of congestion.

I would go with the managed switch so that you can have better control/eyes on that device.  Since it will be powering your cameras (which are very data intensive) you'll want some management of those ports.

The dude will also help you see how chatty the cameras can be.

I would at the very least go with a managed switch, and the Netgear I sent earlier is around 1000.  I would go that route before going unmanaged.

Hope that helps
