I have 4 video cameras (2 xcam2s and 2 wired B&W) that I'd like to hook up to a single video display. I would prefer either a remote control switch (so I can use hawkeyes to perform the switching) or one of those devices that accepts 4 inputs in and puts out a quad picture (the screen divided into 4 quadrants with a camera image in each). Does anyone know where I can get either? Thanks
