Do I need a PC at the camera end if for example it is on top of our building. The WinCam Live camera uses an RS232 serial port. That is one of it's strengths and features.

Power is fed up to the camera via the cable.
So you don't need to find mains power near the camera unless you are using a modem with the camera. We want to setup remote cameras where power may be an issue. Solar power with battery. How much power does the WinCam Live camera need to be powered up 24 hrs a day. HERE for a picture of how the Navy customized WinCam for a solar-powered wireless application.
