5. CCTV Protocols
CCTV protocols allow the DXI system to control an external CCTV switcher. The communications interface is
usually an RS-232 serial port.
Some CCTV switchers have advanced features that may be utilized by DXI systems.
Time/Date: The CCTV switchers indicated can have their time and date set by the DXI system. This allows
synchronization of the DXI time and the time displayed on the switcher.
Presets: The DXI system can send preset information (Pan/Tilt/Zoom settings) to the indicated switchers.
Video Visitation: The DXI system can utilize this switcher in a video visitation system. The switcher has text
display capabilities that will be used for informational messages displaying visitation status and visitation time
remaining.
Alarm point capability: The DXI system can send alarm point outputs to these CCTV switchers. This can be an
alternate method to activate camera->monitor combinations.
