The Lumens VC-AC07 RJ45 to RS232 VISCA Cable Extender can be setup with any brand 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. In addition, the AC07 supports the daisy chain to link up to 7 cameras.
