VDU-4 Video Distributor Unit
The Alpha Communications®/S.T.R.™ VDU-4 video distributor unit is used only with
the VMH24, VMH25 and VH30 series coaxial type video-intercom systems. The VDU-4
is used when the video signal from the lobby entry camera(s) must be split
(distributed) to several coaxial cables.
The VDU-4 gets its power from the system camera DC power supply. All VDU-4
connections are positive screw terminal and coax clamp connector type.
Each VDU-4 has four (4) video outputs. When multiple VDU-4's are used, for systems
requiring more than four (4) outputs, multiple VDU-4 units may be "daisy-chained" to
provide outputs in multiples of four (4).
