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
