VH30C-2D COLOR ReliaBUS™
The Alpha Communications®/S.T.R.™ VH30C-2D (apart-
ment house) series ReliaBUS™ Color monitors are designed to
meet virtually any requirement for video-intercom security
where it is impractical or too costly to run Coaxial and/or
selective 'ring' (point) wires. The VH30C-2D is normally used
in larger multi-unit buildings, but can be used in smaller buildings
These attractive monitors are conveniently surface mounted
right on the wall. Monitors can be changed to desk mount with
the addition of a model TZ30 series desk adaptor.
