mechanism simplifies
installation, guaranteeing a
completely flat and consistent
visual platform.
Thanks to a unique off-board
electronics design, many of the
video wall’s heat-generating
components are removed from
the wall itself and storable in a
remote rack room. As such,
cooling required for the video
wall space is significantly
reduced and the lifespan of the
entire system is extended. The
setup also means that, when
required, the power supply in
the rack room can be replaced in
a few minutes and usually by
only a single technician without
having to dismantle or disturb
the video wall.
Consistent performance
According to managers at the
police department, the wall is
performing consistently at a
high level and often for long
periods – even extended 24/7
duty cycles.
With the Eurotunnel and the
Scottish city of Glasgow’s traffic
management center being
among other customers, Leyard
along with its Eyevis and Planar
brands can offer purpose-built
displays and content
management platforms for 24/7
surveillance to suit budgets and
technical requirements.
A large video wall was
instrumental in this. Providing
city-wide surveillance to
Memphis’s Real Time Crime
Center, the 36 Clarity Matrix
LCD video wall system spans
more than 130 feet across the
front wall of the room.
Replacing a rear projection
video wall that had been in place
since 2008, the move to an LCD
video wall occurred because of
the diminishing brightness of
certain displays and the rising
display lamp costs.
The Visual Control Station
(VCS) video wall processor
enables content from multiple
sources – including surveillance
cameras, maps and cable TV
news. It means a single officer
can get a big-picture view of
something on their own, or
even another officer’s, computer
screen to make more informed
responses to developing
criminal activity.

The essential core for
managing the incoming graphic
and video signals is the netPIXController.
Thanks to multiple
entry points it can receive many
different signal types converting
them for presentation on the
wall. As a precaution against
system failure it is also fitted
with redundant components.
Not only the live images from
more than 300 digitalized IPsecurity
cameras are shown. A
satellite tuner can be activated
to show TV-images, meaning
that in a crisis the technicians
can also receive information
from news broadcasts.
In the near future it is
planned that the radiograph
location plan of all SSB routes,
generated by the geoinformation
system Geotrams will also be on
the screens. Every stop will be
indicated on the map.
Crime-fighting in Memphis
Elsewhere, intelligence-led
policing has had a key role in
reducing crime in Memphis.
