Bluetooth gives a 'crackle' sound
Wi-Fi will produce a 'scratching' sound
GSM gives a 'buzzing' (hum)
DECT is heard as a 50Hz AC transformer hum
The

will change its color
correspondingly.
Please note
that some DECT signals may be not recognized.

Press
the
CORR
button
while
watching the DEMODULATION display to find the
synchronous
fluctuations.
They

show
the presence of correlation, i.e. a radio
microphone.

Step 4. Physical search
Not depending on the results, start a physical search. Visually inspect and probe
each object in the highlighted area. Disassemble, if necessary, lamps, desktop
items, telephones, AC outlets, phone outlets. Inspect all power and phone lines
carefully. Open books, wardrobes, etc. Remember, that a physical search is a
fundamental
operation during the sweep.
Illegal transmitters often have a number
of these typical characteristics:
Compact
Hidden
Handmade or produced with low quantity
With microphones or video cameras
Implanted inside another piece of electronic equipment
Connected to a telephone line
Connected to AC wires or with its own source of power
With antenna
With a SIM card inserted
If you find a bugging device, do not stop! You should continue the search more
carefully
as eavesdroppers often install more than one device. They may install a so
called 'foolish bug' which may be easily detected and some other well hidden
devices that may have remote control and non-standard modulation.
Step 5. Checking Bluetooth/Wi-Fi
Bluetooth and Wi-Fi can be easily used for bugging and therefore needs special
attention. Conventional Bluetooth headsets, smartphones or cameras can be
installed (or intentionally left)
in
premises, in personal possessions or on a body in
order to transmit audio or video. In addition, a well-hidden dedicated bugging
device can be created with the use of accessible Bluetooth and Wi-Fi electronic
components.
Therefore
we
strongly
recommend repeating a scanning of the area with the ANT2
selected and the Micro-Pointer antenna in ANT2. In this mode the Protect 1206i will
detect
Bluetooth
and
Wi-Fi devices only at a longer distance so that location of all
wireless sources will be much easier.
ground noise near the suspicious place.
It is also possible to recognize some typical
communication protocols by the sound they produce:
