Made in U.S.A.    

Note- all ETS microphones are
optimized for the voice band by
trimming the preamplifier's high
and low frequency response to
200Hz-16Khz. The result is
higher intelligibility of the sound
source and lower levels of
background noise.

Note- All 2 way speaker
microphones are now available
with CAT5 RJ45 connectors for
main cable runs. Microphone
audio, speaker audio, power
and a spare pair of wires
(call sw) are all sent down one
CAT5 cable. The result is
savings in cable costs and
installation labor.

Simply add -C5 to any
microphone / speaker part
number. Also be advised that a
compatible ETS interface box
may be required to complete a
working two-way system. See
interface page for more
information
 

Applications for our audio
surveillance products include:
remote monitoring, asset
protection, theft prevention,
national security, homeland
security, casino soft count
rooms, booking rooms,
interrogation rooms, prisons,
sleep disorder centers, therapy
labs, convenience stores, fast
food restaurants, nanny cams,
conference rooms, zoos,
parking structures, elevators,
stairwells, industrial process
monitoring, etc. Anywhere
CCTV cameras are installed,
ETS products can typically be
installed.

Caution

It is the responsibility of the installation
company and end user to install this audio
surveillance equipment in compliance with
state and federal privacy laws. If you are
unfamiliar with these laws, consult a
qualified attorney.

All ETS audio surveillance products contain
warning labels that are to be posted at the
installation site when required by law (this is
generally all that is required). Upon request,
ETS will supply additional labels free of
charge.
