in the past , I worked for a company working on security and supervision.
My job was set up the camera in the bulding ,factory and the others.
therefore , i also have some experience about that .
I know some kind of camera such as IP camera ,zoom camera ,convert camera ..vv .They also have various features .
with IP camera ,you can control it by PC via the internet ,viewing ,moving ,..v.v
To send control information to the camera ,you can use IR remote control
or RF control ( for the wireless camera)
by mean of programming ,you can design a software which control the camera by PC.
using PIC is the best choice for your project.I think that
