The Kramer VS-120 is a programmable scanning video switcher designed to sequentially cycle through up to 20 video and stereo audio sources. Operating stand-alone it accepts up to 20 inputs, but multiple VS-120's can be cascaded to allow as many as 2000 sources to be monitored. It is ideal as a quality control tool in video duplication facilities as well as a sophisticated alarm camera scanner. Switching is performed during the vertical interval for glitch-free transitions between genlocked sources.
The VS-120 can be controlled by front panel buttons, RS-232, or RS-485 commands transmitted by a touch screen system, personal computer, or other serial controller. Operation is fully microprocessor controlled. It is rugged, dependable, and is housed in a professional rack mountable enclosure, which occupies two vertical spaces in a standard 19" rack.
