Need Help with project for a car

Hello people.

i need help building a small circuit ( a tv circuit). i want to incorporate to small cams in the back of a my van, and want that does two cams transmitte the image live to a monitor (or to small monitors) in the front of the van. my problem is this:
-> i dont know whats best linking all through cables or wirelless system.

can anyone help me? and before some just say "you can buy it" i cant do that because i will incorporate this project in a school project.

It sounds like you don't know how complicated is a TV transmitter circuit and a TV receiver. Then use a TV cable instead.

i realy dont know that, but i still dont know how to build the circuit...

You are not going to build a TV transmitter and a TV receiver. They are too complicated.

In a van, there's plenty of room for wires. Wireless is an unnecessary complication.

For future reference, "2" is spelled two.

Composite output cams and two small composite input monitors. Hook them together with coax. Nothing to build.
