The Bolide Technology Group BE-AD300/16 converts an RS-485/RS-422 control protocol signal into a Coaxitron control protocol signal and combines it with the video signal traveling over the BNC cable. Once combined, PTZ control of a camera is possible from a distance using any RS-422/RS-485 compatible keyboard controller or DVR. By eliminating the need to run a separate control cable, users will be able to upgrade to a PTZ camera and connect it to an existing BNC video cable, making it a significant time and cost saver.
