Hi. I have a bunch of cheap CCTV cameras that have SCART outputs. The video uses the normal video pins that can be wired directly into a phono sockets (the yellow one on the front of the TV). I want to be able to switch between cameras on both a timer and by PC control.

How can i switch between the video inputs? I was thinking of using a PIC chip to control which input gets to the output but im now sure what to use as a switch. In the past ive used relays for this but they are big, noisey and use a lot of power. Is there an IC that simply acts like the relay would. When it gets an input from the PIC it connects the video input to the output?

Audio isnt a big concern but is there something that would handle that too? A simple switching IC would be ideal because it would be able to handle both video and audio just like a relay.

Im hoping for something really cheap because i have 5 cameras plus a few other things i would like to attach to it
