Hi I'm looking for a system which involves the following 2 video cameras, most likely just analog A switch between the 2 Small TV something to delay the broadcast of the video to the TV by about 10 seconds. This is for doing sports analysis. The athlete selects the camera using the switch, does the action and then can simply watch the monitor to see how they did. I wanted to avoid using any computr gear if possible and recording isn't needed. Does anyone know of such a product?
