Lumens VC-AC06 - VISCA Cable Extender (RS232 to RJ45)
Lumens' cable extenders can be set up with any PTZ camera and are easy to use. They are more effective than a VISCA cable.
The cable extenders can extend the distance between the controller and cameras up to 300 feet (100 meters) via the RJ45 CAT5/6 cable.
