I have regular hd, full hd and lower quality cameras.

I would like to find simple and cheap hardware, which i can put between cameras and display and it takes in 4 video feeds and outputs one which shows all four videos in one screen split to 4 squares.

 

You will need a video multiplexer...... like these >> http://www.ovation.co.uk/Gemini/Gemini-4.html

Thanks for answer.

I was hoping it would cost a lot less. I don't need any professional level thing.
