How do you connect 4 cameras to Time lapse VCR with only 1 video input?

Answer 1

with a

video switcher - shows one camera at a time

or a Quad - like a switcher but shows four at a time or one at a time and maybe some sequencing

or a mulitplexer - like a quad but with many more features.

Answer 2

They have multiple input adapters at any local walmart or radio shack or anything of the sort. It will have like 3 or 4 inputs on it (depending on what you buy) and one output that will plug into your vcr.
