well does the video feed have to do any thing or is it just to see what is there. (face recognition, motion etc.)
if not you would be able to get away with a simple transmitter and reciever pair that can be used on a Cam corder and be relayed to a computer or Tv screen.
To really help we need alot more info mation like the following:
-will it be use for something computation wise( motion, following things etc).
-What sort of camera did you have in mind eg. web cam, handy cam, blackfin etc
as for the pan and tilt, that is really easy. All you need is a rig that can hold the camera and has 2 servos in side one for tilt and one for pan
