Thank you for producing a very readable Linux magazine. Your longevity speaks volumes about your ability to speak to your target market.
I’ve been struggling to get a competent security system NVR (Network Video Recorder) up and running. I would like to use a dual NIC machine that connects to the LAN on one NIC and to a switch that connects the cameras and devices on the other NIC. The cameras and devices are on a separate subnet. The LAN should be able to access the NVR software to view the recordings and to take clips off of it.
I’m surprised how difficult this seems to be. Either I’ve missed something rather fundamental or this is a black art. The research I have done so far shows the cameras and NVR all residing on the LAN and I don’t want to do that. Imagine a system with a thousand or so cameras and the LAN will quickly become overloaded.
I read an article from your magazine archives that walked through using Zoneminder, but it was a rather simple setup with everything on the same subnet. Would you folks be willing to take that article to the next level and walk through the dual NIC NVR solution? Fred Leg ace, Canada. Neil says: Certainly, if you were looking at a system with more than 254 cameras than a subnet would be essential. IPv6 might offer a solution, if the cameras
supports it, but managing all those cameras would also be very troublesome!
I’d have imagined if we commissioned anything CCTV related we wouldn’t be thinking more than 20 cameras. Anything more would be an industrial solution, but I’m now intrigued!
