May be your grammer means some thing or you mean to say some thing else. Anyways, i would like to say your querry is not clear. The CCTV system is just hardware. When connected to a PC through a PCI card, a software in the PC controls the finctions and too takes care of the recording of all the channels. If you are talking about constructing a complete system, CCTV cameras, PCI cards, Harddisks, Standalone DVR's, all are avilable in open market. any dealer will guide you how to connect it.
If you are asking a software, it will come with every PCI card or DVR purchased.

99% NO. because in mobiles the camera module is just fitted as to use minimum hardware and all the controlling hardware will be on the mother board. Regarding webcam, i am not sure wether you get a video signal "out" or it is fed to the USB interface chip directly.
