APPLICATION
The Alpha Communications®/S.T.R.™ VH30AK se-
ries B&W video-intercom system uses the most ad-
vanced technology available for positively identifying
visitors to a building, and securing the residents.
Visitors call from one or more lobby entrance stations,
andthesystemwillautomaticallyswitchallvoice,video
and door release functions to the calling entrance.
The video image will appear automatically, once a call
is placed, and residents can discretely 'screen' their
calls, before answering. If a resident chooses to reply,
all they need to do is lift the voice handset and speak
normally. Once a visitor is positively identified, the
resident can activate the entrance door release, by
depressingtheDoorReleaseButtonforafewseconds.
With the S.T.R.™ VH30AK, Seeing is Believing!!!!
