nhnanna, I wouldn't get the one I have. I needed one in a hurry so I paid a lot for stuff I didn't need like recorder, multi channels, etc. But it's a "SVAT". You can add up to 4 cams to the monitor. The monitor is the size of a small hand held TV. The old wired camera I had was hooked up to a 19 inch TV, so the picture was much bigger.
Do you want wired or wireless? I can help pick a good one.
