Thanks for the great replys guys, i've contacted a cctv installer for advice and a quotation, as im not sure what experiance the electrician has, i thaught it was all the same sort of stuff, but obviously not, there's a lot more to it.
Also i was looking this camera from 'wait for it..."CHINA"
does anyone know of these, or ever used them.
Also are these cameras in your opinion any good

what do you think of the cameras and the companies themselfs or can you recommend anything a bit better quality.
