First of all, I'm very much a CCTV newbie... I'm building a new house and I've wired for 5 cameras (1 inside and 4 outside). I was researching PTZ dome cameras and noticed that some can "track" movement. That is, the camera apparently pans and follows the moving target. Is this a common feature for PTZ cameras? Is it a camera feature or a feature of the DVR? Thanks.

Thanks guys. I didn't know if my front door camera was supposed to "watch" people as the approached. The hi-res idea makes much more sense to me. Thanks again!
