The DMC-VID4 allows up to four cameras or other video sources to be connected and switched manually, or automatically in sequence at regular time intervals. In sequential switching mode, the video image cycles repeatedly through each available input, displaying one source at a time. The time interval for sequential switching is user-definable.
Video Quad Processor
In quad mode, the DMC-VID4 allows up to four cameras or other video sources to be viewed simultaneously in either dual or quad video windows.
Dynamic Text Overlay
Dynamic text overlay capability allows each video image to be labeled to clearly identify the source being displayed, whether in sequential switching or quad mode.
Local HDMI® Output
Every DM® switcher input card includes an HDMI output port, which can be used to pass the video input signals through to a local video monitor or to feed a second DM switcher for output expansion purposes. The HDMI output on the DMC-VID4 carries the switched or quad processed video signal.
Standalone Switcher/Quad Processor
In addition to its use as an input card for DM switchers, the DMC-VID4 may also be used with the DMCI DigitalMedia Card Interface  to provide a simple, Crestron controllable video switcher and quad processor with HDMI output.
