Hi all, first post here. Very green when it comes to CCTV. I've just installed 4 fixed cameras on my house eaves hooked into a DVR which holds a 1TB Sata drive. I think it's a linux based system with a basic interface. I can view the cameras on a variety of clients, browser/devices, it has all the standard stuff, alarm, motion detection, day/nigh IR, email notification, FTP upload etc... It was a relatively cheap system but it works well. Now I'm trying to get some more cameras with another DVR but this time I'd like the tilt pan type. I see that most PTZ cameras are wireless IP cameras. They need a PC running windows most of the time which is not what I want. I couldn't find any that would connect to a DVR like the one I bought. I thought you could get let's say 3 or 4 dome cameras then move them via the DVR software control. I noticed some PTZ cameras have green plugs at the back and the cables have the two extra wires to plug in. But most IP PTZ cameras I've seen don't. Just a CAT5 plug. I did a bit of reading and I must admit I'm very confused now about which ones to get. Some pointers would be much appreciated. Thanks in advance.

Thanks for the Info. After further reading I now understand the difference between DVR and NVR. I'm starting to get the picture now. My DVR software has a PTZ interface so I'd assume it does support it. I'm not sure yet how it would be wired to the cameras so I'll have to check. I'll take a snapshot of the back and post it here. At the moment my preferred solution would be to get a 4 channel NVR, then hand pick 3 network PTZ IP cameras and wire them via CAT5. Unless you guys can recommend an already packaged/integrated system that does it all already.

Thanks for the quick replies guys. So CAT5 networking sounds like the way to go as far as wiring goes. I can handle that and the networking/programming side of things too. Could you please point me to a DVR model that would support this kind of cameras as opposed to analog system?
