Plug-N-Play EZ-Coax Transceivers gives you telemetry control and access to the camera OSD menu using only the coaxial cable running from the camera. Usually found in high-end PTZ cameras, the NUVICO EZ-Coax hi-tech transmission method allows access to the camera menu, as well as telemetry control using only the coaxial cabling already running from the camera. Available in single channel, EZ-CX1T, and the 8-channel, EZ-CX8T, the transceivers can be cascaded to create a multi-channel transceiver control system at a central location for easy adjustment and maintenance. The EZ-CX1T is plug-and-play out of the box, and features built-in control buttons on top of the device for easy navigation. RS-485 comm ports are built-in to both models for telemetry control using the DVR or the EasyTrak Controller Keyboard, the CK-1000. Some of the camera adjustments that can be made over coax cable are as follows: brightness, Super BLC, LED intensity, LED On/Off, and BMB (Brightlight Masking Block).
