VH25MS / VHC25MS Video-Intercom Monitors with 'CAMERA MOVING'

The Alpha®/S.T.R.™ VH25MS (black and white) and VHC25MS (color) series monitors are designed to meet virtually any requirement for video-intercom security. 

These attractive monitors are conveniently surface mounted right on the wall. Monitors can be changed to desk mount with the addition of a model TZ25WH desk adaptor. 

All VH25MS / VHC25MS series monitors feature a crystal clear 3.75" flat screen LCD monitor (measured diagonally), textured finish handset (to minimize scratches and fingerprints), electric buzzer signalling (adjustable), heavy duty coiled cord with strain relief and two (2) momentary button switches. These switches can be used for door release or other signalling functions, depending upon system configuration. The monitors feature a front-mounted 'ON' button to turn the monitor on without being called from an entrance panel. In addition, the monitors feature LEFT and RIGHT camera moving control buttons to move lobby entry camera from side to side. 

With the addition of a low-cost Model R2007 Alphatone™ chime adaptor, you can easily change the electric buzzer to a modern warble chime tone sound.
