This one is a little out of my league.


I have just setup a ispy server at work to run a few different grid camera screens around the building. I have 13 cameras linked back to the cctv dvr channel streams. The DVR is on a separate network (for not business critical gear, laptops, phones) (Network A). I also would ideally like to have two IP cameras in the system that are on the work/business network (Network B).


The computer is on network A currently. I get a feeling that its not as simple as getting a second NIC and plugging in network B?


Edit: Bugga I just realised this would probably be better in LAN topic since its not unique to the cameras. Oh well

It is about that simple, just use a different IP address range (or subnet) on each network, and don't specify any "default gateway" on the 2nd network.  

 

The IP stack on the PC will figure out that IP addresses on network 2 belong to the same subnet as the adapter on network 2, and route that traffic appropriately.

Correct. My home network (which I admit is overkill) has different networks for different things. I run VLAN's however in your case it is as simple as popping another Ethernet card in and you're away (just do what ubergeeknz said). It really sounds like you could use some VLAN plumbing though ;)

FWIW It's an utterly terrible idea from a security perspective to do that. 

 

The "proper" but expensive way would be to put in a decent router or more likely an L3 switch, and configure appropriate ACL's such that only the camera traffic can traverse the link.

I've got that sort of setup on my network however it is not everyone's cuppa tea :) - Cisco is pricey though, the Ubiquiti Switches can do it too and are far cheaper!

Oh okay lol

 

I'm sure I could use some nice cisco gear etc but with no budget (utilising an old pc with quad graphics card already) that makes its a bit harder, so second NIC we go :)

 

Cheers guys :D
