Multi-channel detector

of wireless protocols

Features

The Protect 1207i is a new measuring device which can be successfully used

by engineers or counter surveillance specialists as a reliable tool for tracing

different digital transmissions such as GSM, Bluetooth, etc. New methods of

'listening and watching' with the help of modern technologies has become

widely spread in our times. For example, a tiny GSM transmitter is accessible

at practically any internet spy-shop for only 100-200 USD and can listen to all

your conversations in the office or at home. And perhaps more importantly the

Bluetooth protocol has been specially designed to transmit voices or conver-

sations with high quality at a distance of up to 100 m - it can easily be used for

bugging.

cannot detect such weak and non-continuous signals as Bluetooth, Wi-Fi or

Wi-Max. Even more powerful signals like GSM-1800 are also hard to detect

because of their low sensitivity at higher frequency ranges.

The only way to reliably detect wireless protocols is to use pre-selector chips

(saw filters) which attenuate all other signals except the desired ones. This is

the method implemented in the Protect 1207i which has 6 channels for

different frequency ranges and can simultaneously detect 6 different kinds of

transmissions at a distance much greater than any common RF detectors.

Such qualities make the Protect 1207i a very desirable and reliable device

during counter surveillance sweeps.

It is recommended that all sources of RF waves are detected in the premises

during a search. It is necessary to determine the nature of every source -

whether it is a regular transmitter like a Wi-Fi access point or it has an unclear

origin and thus should be inspected and probably removed.

The following are the most probable ways of eavesdropping with the use of

wireless protocols:

Ways of eavesdropping

A small box with a SIM-card insert. Can transmit acoustics or conver-

sations from a landline telephone to a pre-programmed number via

the GSM network. Can be controlled form a pre-programmed number

with the help of SMS or programmed from a PC. It is powered from a

GSM/WCDMA/3G/LTE

Has a built-in video camera and can transmit captured still images,

video and acoustics. It is usually used for security observation but

can also be used for illegal bugging. On the GSM network still

images can be transferred with the use of GPRS/EDGE, but 3G

A cellular telephone converted into a 'spy phone' with the help of spe-

cial, illegally installed software. The software allows the illegal listener

to activate the microphone of the telephone and transmit acoustics to

a pre-programmed number. The control of this device is accompli-

The sensitivity of a common RF detector (bug detector) is spread along a wide

frequency range, usually 3, or even 6-7 GHz. This means the common detector

GSM/GPRS/EDGE/3G/LTE video camera

allows for the passing of real-time videos.

Spy phone

shed in a similar way - by SMS or from a PC.

A small device which is only limited in its size by the desired battery

source. If provided with an external power source these devices can

achieve a size of 1x1x0.5 cm. They are hardly detectable due to:

1) low power, non-constant transmissions at relatively high frequency

ranges; 2) the possibility of remote deactivation thanks to the duplex

possibility of Bluetooth; 3) The possibility of gathering information, hol-

ding it and then transferring it by remote inquiry during night time -this

means that no radio waves are sent during working hours 4) its small

size.

A small device which can be installed in a target's car or hidden

among their items for personal tracing. Detects its own coordinates

with the help of a built-in GPS receiver and then transmits them with

the help of the GSM/3G network or can record a trace into its built-in

memory. Most of these devices also have a built-in microphone and

allow the operator to listen to acoustics in addition to knowing its

Bluetooth

Spy phone

Similar to GSM, the acoustics around the telephone can be picked up

and transmitted via Bluetooth if the telephone has special 'spy' soft-

ware pre-installed.

Wi-Fi/Wi-Max

Wi-Fi bugging device

Can transmit acoustics or high quality videos using the standard

wireless network. The information can then be easily forwarded onto

the Internet and monitored from anywhere in the world. Controlling

the device can also be done via the Internet.

Wi-Max bugging device

In addition to the possibilities provided by Wi-Fi, Wi-Max gives direct

Internet access and a longer coverage distance. This can give the

eavesdroppers practically unlimited possibilities in monitoring and

control, including transmitting of acoustics, real-time video, remote

controlling, collecting information with a fast transfer time, etc.

Spy phone

Again, having pre-installed 'spy' software in a mobile phone with

Wi-Fi (i.e. a Smartphone) allows the eavesdropper to listen to the

surrounding acoustics in real-time or they can initiate the downloa-

ding of pre-captured data.

coordinates.

Bluetooth bugging device

The Protect 1207i has been designed to detect all of the mentioned kinds of

bugging devices.

Bargraphs

The closer the unit is to the source of transmission the higher the bar graph

level will be. Some powerful sources may cause full illumination of the display

(this also happens when the unit is in close proximity to a transmitter). In such

cases use the attenuator function (ATT+/ATT- buttons) to alter the sensitivity.

It is also recommended to use the attenuator when there are many back-

ground noises in the area which can create difficulties before a search. Please

note: The vibration function will turn on when the SIGNAL STRENGTH of any

of the bar graph indicators approaches the level selected in the setup mode.

The Protect 1207i has 6, 10-segment, 'SIGNAL STRENGTH' bar graph

indicators providing the following precise information to the operator:

CDMA/LTE800 (4G) standard

GSM 900 standard

GSM 1800

WCDMA (UMTS, 3G), most of

the modern DECT telephones

or as above plus GSM 1900

and CDMA 1900

Wi-Fi access points and

adapters, Bluetooth devices

All transmitters in the range

of 2.5-6GHz, including most

kinds of the Wi-Max/Wi-Fi

High/LTE (4G) protocols

The Vibration mode is convenient when probing difficult to reach objects and

places. The operator can work without the necessity of watching the bar

graphs a high RF level will be indicated only by the Protect 1207i's vibration.

The Visual mode can be turned on when help is needed in detecting what kind

of protocol is being transmitted in the near vicinity. The ‘EXTRA DATA' display

will show the results in this case.

The Listen mode is convenient for a fast search as an experienced operator

may be able to distinguish between different types of signals. (Please

note that this mode is not suitable for covert searches, as the transmitter will

'hear' sounds in the room.)

Press and hold the joystick's button and then turn the Protect 1207i on. Use

the arrow up or down to select the threshold level for vibration. After this proce-

dure has been completed press the joystick's button to start normal operation.

The left arrow of the joystick returns the unit to 'SILENT' mode.

Pressing the joystick's button will turn on the Listen mode temporarily

Setup mode

The right arrow on the joystick control of the

Protect 1207i is used for selecting the desired

indication method. There are four modes available:

Silent - used in most cases for covert operation.

The operator should watch the bar graphs in

this mode

Listen mode, when the unit's speaker produces

a demodulated signal

Visual mode, when the unit tries to recognize what protocol is being trans-

mitted in the current signal and shows the results on the ‘EXTRA DATA'

display.

Vibration, in this mode the unit's vibrator turns on when reaching the thres-

hold of any of the 6 bar graphs (the threshold can be selected in the

setup mode)

Joystick controls and operation mode

The Protect 1207i is powered by two AAA (LR03) batteries. It is recommended

to use alkaline batteries in order to reach optimal working duration. The

'LOW BATT' indicator will turn on when the batteries are nearing exhaustion.

Power

Usage

Sweeping the room

Please note that the Protect 1207i is an auxiliary device which detects com-

of sound such as a stereo system or radio. This sound source has two very

important functions:

Voice activated transmitters will be activated

Your actions will be masked

Choose the operation mode by sequentially shifting the joystick to the right:

munication protocols only. For full, irrefragable results the premises or vehicle

should be swept with a number of different types of equipment, including wide-

band RF detectors, radio-monitoring scanning systems, non-linear junction

detectors, video-camera detectors, thermal vision devices, etc.

A wireless detector is an additional but irreplaceable component for such a

professional kit and due to its qualities the Protect 1207i is the best selection.

Close all drapes in the room. Turn on all the lights and activate any other

devices to imitate normal conditions. It is also advisable to turn on a source

Enter the room and turn on your Protect 1207i. Watch the bar graphs and

if they show increased levels (more than 4-5 segments), turn on the atte-

nuator by shifting the joystick in the upper direction (ATT+).

The corresponding LED will show the attenuator has been turned on.

Note: Later you can turn off the attenuator by pushing the joystick in the

opposite direction.

Silent - the default mode which is automatically selected after turning

the unit on. It can also be selected in the sequence of modes (joystick

right) or chosen quickly by shifting the joystick to the left. This mode

is useful when a covert procedure is necessary.

Before starting sweeping, some preparation tasks should be carried out.

Firstly, it is necessary to consider the time and individual circumstances of the

sweep. Due to there being lots of devices which are remotely controlled it is

recommended to carry out a sweep during working hours in real situations

when the eavesdropper most wants to listen. It may be necessary to arrange a

fictitious meeting. Nobody has to know about the pending search.

Bluetooth gives a 'crackling' sound

Wi-Fi will produce a 'scratching' sound

GSM gives a 'buzzing' (hum)

DECT is heard as an AC transformer hum

The Listen mode is more convenient for locating and inspecting

the RF source as the operator can learn about the source by hearing

the demodulated signal. An experienced operator may be able to

distinguish between different kinds of transmission:

Note: The above is a guideline only as the sound may vary depending

on the current mode of transmission and the type of the protocol used

in the specific country.

The Listen mode can be turned on temporarily from any mode by

pressing and holding the joystick's button.

Move around the room with the Protect 1207i while watching its bar graphs

or paying attention to the vibrator. Turn the lights and other equipment in

the room on and off. Walk around the room, continuously watching the

indicator or feeling for the Protect's vibration. The bar graph level will

increase or decrease when the detector is closer to, or farther away from a

transmitting device.

Probe all objects which may contain a hidden surveillance device. When

you get close to an RF transmitting device some of the bar graphs of your

Protect 1207i will rise (or the vibration will appear). The distance of

detection may vary depending on the situation. Usually the Protect 1207i

is able to detect a GSM 'bug' at a distance of 2-10 meters and a Bluetooth

channel at 50-150 cm, although it is recommended to probe objects at a

closer proximity 10-30 cm.

The bar graphs can display 10 different levels. You can use the attenuator

to decrease the sensitivity when performing the location procedure (finding

the source of the RF field). Use the ATT+ arrow when the bar graph shows

a high level to force the unit to react to a stronger field only.

Please note: If you want to continue sweeping after the location of one

bugging device, it may be necessary to restore the normal sensitivity of the

Protect 1207i by using the ATT- arrow.

If you have found a source of wireless transmission inspect it very carefully

to detect if it is a 'legal device'. Consult IT employees to become acquain-

ted with the scheme of wireless access points and the location of wireless

telephones used in the office.

The Visual mode gives extra information to the operator by showing

a suggested protocol on the display. The recognition is based on

analyzing the demodulated signal and is in most cases sufficiently

accurate. Enter this mode when inspecting the RF source.

The Vibration mode allows the operator to avoid constantly watching

the bar graphs when inspecting areas that are difficult to access, and

to achieve secrecy during a sweeping procedure. By default the

vibration turns on when a constant signal has reached a bar graph

level of 5. You can use the Setup mode to change this threshold:

Firstly, turn off the Protect 1207i by pressing and holding the joystick's

button, then turn the unit on again in the normal manner. Use the

up/down arrow to select the desired threshold level of vibration. After

this procedure has been completed press the joystick's button to start

normal operation.

Illegal transmitters have a number of typical signs, they are:

Compact

Hidden

Handmade or produced with low quantity

Contain 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 an antenna

With a SIM card inserted

Regardless of the results, apply all other sweeping devises available and

carry out a physical search. Visually inspect and probe each object in the

highlighted area. Disassemble, if necessary, lamps, desktop items, tele-

phones, AC outlets, phone outlets. Inspect all power and phone lines

carefully. Open books, wardrobes, etc. Please remember, that a physical

search is a fundamental operation during a sweep.

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.

When talking about phone lines we should firstly mention GSM/3G/LTE(4G)

bugging devices, which can pick up conversations from a normal landline

telephone and then transmit them via the GSM/3G/LTE(4G) network. It is

also probable that a Wi-Fi/Wi-Max or Bluetooth channel can be arranged to

transmit the information.

The Protect 1207i has been specially designed to detect all of the mentioned

kinds of telephone bugging devices.

Checking telephone lines

Telephone bugs may be installed anywhere a phone line lays. It may be within

the phone set, the phone outlet, connecting box or cable. Most telephone bugs

activate only when the receiver is off-the-hook. Therefore the sweeping of

phone lines should be carried out only when the receiver is in this state.

Start checking from the phone set itself. Place the Protect 1207i near the set

and lift the receiver. Watch for an increase of the RF level (or starting of the

vibration). (Please note: It is pointless to test wireless (radio) telephones, for

they act exactly like a bugging device themselves due to the use of radio

waves. Only a physical inspection of these items is sufficient to know if they

are bugged.

Mobile phones, set up in the listening mode (intentionally by establi-

shing a call or secretly with the help of the 'spy software')

Bluetooth transmitters (real listening devices or conventional Blue-

tooth devices converted into bugs - headsets, headphones, etc)

Personal GPS trackers

Different kinds of listening and watching devices using communication

protocols for transmission

The Protect 1207i can be used for detecting the following bugs carried on

people:

If necessary turn on the attenuator. While carrying the Protect 1207i, approach

the person. An increased level on a bar graph will show activity at the corres-

ponding range, which can mean the person has a transmitting device. If you

change location you will need to select the necessary attenuator mode in

accordance with the background noise.

Testing procedure

Testing people

Recently a great number of different vehicle tracking devices have become

available on the market. These trackers use the GPS system to receive

the coordinates of a car and then may transmit them via the GSM/3G/LTE(4G)

network to a monitoring centre. The Protect 1207i can be used for the

detection of waves being sent from car trackers. When inspecting the car take

into consideration the following facts:

Testing vehicles

Another way of testing people is to place the Protect 1207i on the desktop and

watch the bar graphs carefully when the person approaches the table and sits

down.

Move the detector along the phone line while keeping the receiver off-the-hook.

Check all the outlets and communication boxes. If possible ask a second

person to lift the receiver and then hang it up repeatedly. If you see that the

RF level changes when the line is activated and deactivated, this is a sign of a

bug's presence. Try to locate the place where the RF level is highest and then

perform a physical search.

A GPS tracker can collect coordinates and upload them only when an

external query is made - the transmission may not be constant

It is unlikely that a GPS tracker is transmitting information when the

vehicle is standing still

A GPS tracker may transmit conversations and video or still images

from inside the car
