BM3
Door entry phone for PABX
BM3 is a smart and cost-efficient Bewacom door entry phone that con-
nects to a company’s existing PABX internal telephone system in just
the same way as any other extension in that system. The BM3 makes it
possible to unlock the main entrance door‚ for example‚ via the press of
a button at any of the telephone extensions that are connected to the
company’s internal telephone system. Installation is fast and easy with
minimal cabling required.
The BM3 also has a built-in codelock with four codes‚ two of which can
be set so that they are only valid during certain times of the day or
week. The major advantage of the codelock function is that it allows
you to set codes that employees or special visitors can use to enter the
building‚ rather than having to call someone who is already inside to
buzz them in.
The BM3 also includes a tamper switch and an output for camera con-
trol. The tamper switch is very useful in that it can be used together
with the SK5 security unit to eliminate the possibility of opening the
lock by using battery power directly on the lock cables.
A video surveillance camera can be connected to BM3 via its output for
camera control. The BM3 can trigger the camera to start filming as soon
as a visitor pushes a call button on the BM3‚ for example. This video can
either be viewed on a connected monitor directly by the person who
picks up the call (the receptionist‚ for example)‚ or it can simply be
saved in the video surveillance log and viewed later‚ if required.
