the 16 channel unit, along with the HDMI, VGA, and single composite spot monitor, has two additional , what appear to be, VGA connectors that allow u to connect what looks like a VGA to 8 BNC adaptor. Using both of these ports u can loop out all 16 individual channels. As i stated, they loop out at their native resolution, and I need someway to convert this AHD resolution video down to composite to feed to the Elan system video-to-IP converters so they show up on the keypads
