Hi, thanks. They want to have different views on the two monitors, not mirrored monitors, otherwise this would have been my choice, using a KVM extender. I have passively split the analogue signals before, but not over longer distances. This was my concern. I see active splitters available, but for so for AHD etc.

Hi. I am looking at two old cameras which are currently connected to an old 4 way DVR, displaying on a screen in an office. The recorder hasn't recorded for years. Ideally they would like to have the cameras signal split to a second new DVR in a different office which has capacity left, and has an HDD in it and working. The first recorder they wish to retain to allow live viewing only. I have split CVBS in the past over very short distances with no problem, simply with a BNC T connector. I assume this is not the best method? It is only short lengths here, circa 15m camera to each recorder. What would other people do? There are active splitters for HD analogue, but nothing seems to pop up for old CVBS. Cheers.

I guess. Although, have seen some NVRs with dual NICs.

I had thought that, but some NVRs don't have facility for two NICs. Which make do you recommend?

Thanks. I was thinking of using two of these: http://www.misco.co.uk/product/127264/NETGEAR-PROSAFE-24-PORT-POE-10-100-SMART-SWITCH-WITH-4-GIGABIT-PORTS It states four gigabit ports, but then states 2xgigabit and 2xSFP ports? It also states 100mb switching - does this mean it wont make use of 1000mb on the gigabit ports? I would want three gigabit for NVR, camera switch uplink to other side of warehouse, and gigabit link to existing network. Cheers.

Looking to install some ip cameras. Initially 12, but customer wants a 32way recording NVR for the future. Not having used IP cameras before, I am a little concerned with upto 32 cameras? Even if I install a dedicated network for the cameras, is 32 not going to bog down the Ethernet connection to the NVR? How many cameras at good high res/frame rate are good for 10/100 link, or gigabit link? My initial 12 will be connected to two poe switches due to site layout, and was planning on these two switches going back to one switch, and then the NVR? Sorry, complete IP cam newbie!

I have a couple zeus's setup and can watch back recordings fine. Added a new I-Zeus, and while it will display live footage, it will not play back recordings (error message, No Record !). Is this a known issue, or just me? Thanks!
