a cctv quad circuit??

Hi all,

i know this has been posted before, and as imagined, the answer was simply that cctv quads are dirt cheap these days.

But i want to build my own, I have 3 cameras i purchased on ebay and want to build a circuit that will put them in a quad fashion and display them on to my TV. the last matrix area (2x2) will be blank and display a black screen or say something else.

Can help me with some guidelines???

thanks

Very difficult project. Just buy one since they're cheap.

If you have to ask, you're not capable of doing it - it's a massive hardware and software project.
