FOCUS ACCESS
ENTRY STANDARD Installing LPS 1175-compliant security portals is the best way to prevent forced entry to
commercial buildings, argues Martin Washby, Technical Services Manager at Meesons AI
Damage caused by unauthorised entry into
commercial buildings can be far-reaching,
not just in terms of the but also for the safety of
sta . Owners and managers have a duty of care
to ensure that only those people who should be
in the building gain access.
Criminals will always try to get in through the
building’s weakest point, which in most cases
is the entrance. Thieves know there is safety in
numbers and will o en try to ‘tailgate’ their way
in unnoticed, closely following the person in front
as they pass through the physical entry barrier.
An easy way to prevent this is to specify a security
portal or speed gate that is fitted with antitailgating

features.
Choosing the right anti-tailgating system depends
on a number of factors. The starting point is usually
an assessment of the overall level of security risk;
this will determine the kind of physical entry access
needed, and with it the level of anti-tailgating
technology. This is influenced by factors such as
whether the entry point is monitored by security
sta and the number of people entering and exiting
the building.
Speed gates are o en chosen for buildings
where there is a medium to high volume of tra ic
because they provide the optimum combination
of performance, throughput and aesthetics, while
preventing tailgaters. Buildings that require more
specific entry control measures may well find that a
security portal o ers the best solution.
SECURITY PORTALS
Security portals only allow one person to transit
through the interlock at any one time, and only
a er they have presented their ID badge, card,
biometrics or Pin. Our APD ultrasonic sensors, for
example, scan inside the portal to ensure that only
one person has entered. If more than one person is
detected – indicating someone is trying to tailgate
their way into the building – the internal doors
