team can get more insight into an emergency
or security situation, such as verbal cues like
names, nicknames or languages that are spoken;
levels of aggression; and sounds of a door
opening or an alarm sounding.
Audio's Extensive Use
in Range of Applications
In enterprise security, it is exciting to witness
how audio technologies are being leveraged to
their full potential and being incorporated into
facility security plans.
For example, in manufacturing plants,
high-defi nition audio solutions ensure that
plant operators can communicate to the entire
plant or to selected zones. Th e perimeter can be
protected via automated messages if an alarm is
triggered. In buildings and facilities, audio and
intelligent communication solutions provide
instant communication in an elevator, at loading
docks, at the reception desk, and in parking
garages, to help employees, visitors or vendors
who need it.
In hospitals, audio and intelligent communication
solutions allow access and crystal-clear
communication to restricted areas, cleanrooms
and isolation rooms. Th ey also allow quarantined
patients in isolation rooms to communicate
with staff without the risk of infecting
others. In retail stores, instant voice communication
is the key to delivering a quality customer
experience, and intercom solutions and
speakers provide direction to customers, help
security guards to perform their jobs better, and
enable communication between offi ce staff and
sales personnel.
Audio solutions in prisons provide communication
assistance for visitors, cell communications,
and with prison management systems
to enhance a guard's insight into situations
and events.
Audio also provides a secondary verifi cation.
For example, when a security guard sees something
via video surveillance, all they need to do
is push a button on an intercom solution and
talk. If that person is lost or simply needs assistance,
security can talk to them and provide
directions and reassurance. Or, if that person
demonstrates that they are there to cause damage
or harm, the security offi cer can warn them
they are being watched and heard. Th e result
could be a dangerous situation that is mitigated,
as if someone knows they're being watched,
they are more likely to stop what they are doing

and leave the scene.
Beyond security, audio and video solutions
improve enterprise business operations, such as
customer service, where delivery drivers receive
instructions on package receiving locations,
and via audio and video with an intercom, verify
that a shipment was delivered. Audio solutions
also assist with directives for visitors. For
example, a patient who seeks access to a medical
center for an appointment can hear important
instructions from the medical staff via an
intercom solution before they enter the facility.
Achieving Clear & Intelligible Audio
So we know that audio is not new to the security
industry. IP intercoms, loudspeakers, twoway
radios and emergency help stations are being
used in multiple facilities every day.
Yet, are all of those devices delivering crystal-clear
audio? Imagine these scenarios:
▶ A visitor approaches an offi ce entrance
that is just off a busy street. Th ey press
the intercom button but have diffi culty
hearing and being heard.
▶Workers in the warehouse need to speak
to the front offi ce, but when they place
the call they have trouble hearing or be
heard over the forklifts and fans.
▶ A delivery truck pulls up to a gate with
a sign that says, " turn off engine before
pressing intercom button. "
What's being poorly handled in these situations?
It's the need for highly intelligible audio,
every time. Is that need being met? If an interOCTOBER
