NOTE: This PSI Product Test
was carried out by an
independent third party,
not editorial staff. The
manufacturer had no input in
the review or the final result
The pack contains all the necessary items for
a single door video intercom. It is part of a
larger range that can provide multiple door
to multiple room systems.
The IP54, IK08 rated door station provides a
170° image with a stated 5 lux minimum
illumination at the 50cm optimum focus point.
Operation is stated to be from -10°C to +60°C. The
internal Video Master Station features a 7” touch
screen and has facilities for monitoring additional
security devices. The system is expandable so
that up to 4 doors can be monitored and you can
connect to up to 7 sub master stations.
Getting Started
The system is relatively straightforward to
connect up, requiring just a single pair cable
between the Master and Door stations and the
fact that this is unpolarised simplifies the
connection, however, it is clearly stated that this
must be a non-shielded parallel 2-conductor cable
not a twisted pair. Distance from Door to Master
station can be up to 100 metres with suitable core
size or extended to 200 metres with an optional
long-distance adaptor.
It was disappointing that the power supply
provided was only suitable for DIN rail mounting
with no mounting holes for wall or box fixing. The
fact that there are only terminal connections for
mains input means that a lead must be made up
to provide power; while this should be no
problem for an installer it is unusual these days
for such products not to have a suitably prepared
standard power lead. The installation instructions
make it clear that the power supply must be
installed in “a case for electrical use in an auto
extinguishable material…”.
On the rear panel of the master station are two
centrally located screw terminals for the 24v DC
input from the power supply. The connections for
the main door station and up to 3 additional
doors are through 14 push-fit connectors down
the left-hand side of the panel protected by a
clear fold-out cover. An 8mm strip-length slot is
set beneath the connectors for guidance.
A four-way and a twelve-way connector provide
lock relay expansion and alarm handling. The
handset which is magnetically held in place
connects with an RJ11 connection in the monitor
base.
The Master Station is designed to be fitted
onto a supplied wall-mounting plate though there
is mention of an MCW-S/A desk-mount being
available in their on-line specification sheet.
Operation
At first power-up the monitor requests Time &
Date details to be entered then once confirmed
presents the Home menu screen. It was found
that the time & date information only held in
memory for one or two days if power was removed
so this will need to be re-entered if power is
removed for extended periods.
The Video Door Station has a name plate area
that is continuously illuminated by a low level of
LED light. When the Door Station button is
pressed, a bright white LED illuminates the
subject and the Video Master Station displays the
image and chimes twice. Alongside the image on
the right-hand side beneath the time and date
and a Record indicator are five large touch
buttons for Talk, Lock release 1, Lock release 2,
Menu and End. Audio from the door is immediate
but only transmitted to the door if the Talk button
is pressed for hands free communication or by
picking up the handset for private 2-way speech.
It was noted that the Door Station is supplied
with 8.4V DC when in its quiescent state and this
rose to 16.8V when a call was initiated.
A slight ticking noise was present in the
background on the audio during a call but it was
not clear if this was due to the test layout.
The internal memory can store images from up
to 20 calls or with the addition of an SDHC card,
up to 1000 call images can be recorded. Up to 6
images per call at 1 frame per second are stored
to internal memory and up to 40 images per call
at 4 frames per second if an SDHC card is fitted.
Images can be Locked to prevent overwriting if
required.
