With this device you can convert up to 16 cameras to a single CAT5/5E/6 using BNC connectors for up to 1200 feet. Add a second 16 channel HD balun and you can convert the video back to BNC. Perfect for when you want to run multiple cameras to nearby locations on a single cable. This is also a great way to plan for future changes because you will have network cable in place and you can remove the baluns and add HD 4K cameras down the road! ***Please note these are sold individually, NOT in pairs.
