• Very concealed transmission due to very
small bandwidth of transmission, max of 19
kHz.
• Digital spread spectrum packet technology
provides transmission in several short
bursts per second making the transmitter
undetectable with conventional RF
detectors.
• The transmitter delivers excellent quality
sound at range of up-to 1.2 Km (in open air).
• Integrated SD card recorder.
• Great power saving: when turned o the
transmitter consumes very low power.
• Extra small size: great for concealed
installation.

ACU-TSK
Tactical Surveillance Kit
The Acustek Tactical Surveillance
Kit (ACU-TSK) has been designed
by Acustek as a combination of all
the audio and video surveillance
solutions currently available in the
product portfolio. It is intended as
an essential professional kit for
intelligence team, law enforcement
agencies and surveillance operators.
The R&D carried out by Acustek in the last
5 years, has led to the nal stage of all the
surveillance solutions with a continuous work
put into improving products, collaborating directly
with the end users and providing all the technical
support needed to deliver the best product
possible to every client. With the
ACU-TSK we decided to oer a full set of
options that may be needed in a vast range
of operational scenarios, all included in one
ruggedized carry case.
The content of the ACU-TSK may vary depending
on new product released (usually automatically
included in the deliver set) and we can also tailor
the kit based on the client requirements.
