2 to 4 channel video multiplexer for robot

Hello guys,

This is my first post but I have been reading the posts for some time.

I am building a medium size robot that will have up to 4 video sources that I want to be able to control. The best thing I have found so far has been the "X-QVC-EM" engineering module from

. I have 2 questions:

  1. Has anybody used this before, and if so how well does it work? The price is really good, I have seen similar units for alot more money, but you never know.

  1. Anyone have any other ideas or recommendations? I need 4 video inputs that are 75 ohms, I want to be able to choose which source is displayed on the screen, and I want simple TTL control.

Thanks guys.

Carl.
