MEFF M1-PRO Multifunction TSCM Analog and Digital Bug Detector
Introduction
Multifunction analog and digital detector M1-PRO is designed and manufactured
in Italy according to high quality standards.
Detecting hidden high-tech surveillance devices used by foreign agencies,
terrorists or criminals is now more difficult. However, with the next
generation M1-PRO multiple detection system, the operator will find hidden
devices, whether wireless or wired, using its array of smart probes that are
tuned to detect these hidden threats from 0 up to 20GHz .
The system takes the operator to the hidden threat with its distance measuring
tool which pinpoints the location of hidden transmitters or transmission link
such as GSM LTE 2G 3G 4G 5G WIFI mobile phone Bluetooth hand audio or video
devices. Real-time analysis data is logged and stored directly in the system
for immediate identification of current or historical threats.

Directional Omini antennas
Two man-direction antennas are supplied, capable of detecting the signals
present in the environment to be reclaimed in all directions.
Screw the antennas into the ANT1 and ANT2 inputs for use.
Directional Antenna
A directional antenna is provided which can detect the signal following the
precise direction. The antenna can be used in both the ANT1 and ANT2 inputs as
needed. Screw the antenna into the ANT1 or ANT2 input for use.
T1 antenna
This antenna forces the locators in stand bye to transmit the signal to be
detected. The T1 antenna will saturate the tracker signal in stand by and
force it to restart and then transmit the signal.
Keep the detector switched off, insert the T1 antenna into the input (as in
the photo) and place the detector in the car to be checked for 5/10 minutes.
It is advisable to enter the car first, insert the T1 probe and place the
detector on the seat, then close the door and move away from the vehicle. For
5/10 minutes no one must be inside or near the car.
After 5/10 minutes get into the vehicle and immediately remove the T1 probe,
turn on the detector and start the vehicle sweeping procedure.
Warnings
The T1 probe is very powerful and saturates the GPS signal this means that
when it is in operation it is recommended that nobody is in the vicinity of
the vehicle because the probe gives off an ultrasonic saturation signal.
Approach only to activate and deactivate the probe.
T2 antenna
This antenna is used to detect laser and infrared microphones, these devices
are very dangerous because they can be installed hundreds of meters outside
the environment to be monitored. Insert the T2 antenna in the entrance (as in
the photo) and pass the probe uniformly over all the windows of the place to
be reclaimed. If the probe detects a spying signal a blue LED on the back of
the antenna will light up. The led stays on until the detected signal is
constant, if the detected signal is alternating you will have several flashes.
To identify bugs and infrared spy signals present inside the environment, the
entire environment must be swept using the T2 probe as if it were a
directional antenna. T3 antenna
This antenna generates a particular ambient noise which is used to wake up the
audio and video bugs in stand by and voice activated, it forces the activation
of the transmission of the spy device so as to be easily identified by the
detector. Insert the T3 antenna into the input (as in the photo) at this point
the antenna is activated automatically and you can start sweeping the
environment in order to identify the presence of spy devices. 
T4 probe
This probe allows you to sweep the environment and find audio and video micro-
cameras on, off or not powered, it can also identify the black infrared of spy
micro-cameras. 
The probe has a
color video monitor with integrated camera from which you can see the black
infrared of the hidden micro-cameras.
Monitor operation:
Once the cable is connected to the central unit, the monitor will turn on. To
keep the display on, press the (on) key every 10 seconds (this will activate
the IR identification function and keep the display always on ).
The probe also has a led monocle to find the micro cameras even if they are
switched off. The probe connects via its supplied cable (as in the photo), the
probe is activated automatically.
When using the T4 probe, keep the detector off. To restart probe T4, press the
Power key.
To activate the LEDs to use the monocular, press the LED key.
The LED button has 4 lighting modes, each time it is pressed a different power
and flashing mode will be activated.
The LEDs are red and are designed to quickly reflect the optics of the micro
cameras. 
- Power key
- LED activation key
- Vision monitor for the built-in camera
- Vision monocle
- LEDs (RED)
- Micro camera
Thermographic probe
This probe uses thermography technology to identify the presence of heat
generated by both battery and mains powered spy devices.
The thermographic probe must be passed over objects or points with no heat in
order to check whether there are any spying electronic devices inside them.
Two inspections are recommended:
- Survey the environment or vehicle with the power still on
- Inspect the environment or the vehicle after turning off the power and waiting for cooling
Insert the probe into the input (as in the photo) using its connector, it will
be recognized automatically and will activate immediately.
When using the T4 probe, keep the detector off.
- Detection of the heat point
- Temperature measurement
- Environmental thermography detection bar
- Thermographic detection sensor
Using the MEFF M1-PRO APP:
Download APK APP and install it on your Android device.
In the package there is a jack cable and a usb type c adapter.
The jack cable can be connected directly to the headphone input of any android device, the screen will automatically turn off after 10 seconds and the “LED light on the device will remain on at this point you can open the MEFF M1-PRO app.
Otherwise, if you have an android mobile phone with a usb type c input, connect the adapter and then insert the Jack cable inside, in many versions the detector stays on and you can view both the app and the detector display live.
Open APP MEFF M1-PRO, you will find two modes available:
Detector Mode 1:
In this mode you can detect the signal in db, have a graph of the detection
and use the history for environmental monitoring.
Click onSIGNAL
In this screen you will see the signal detected in db represented.
When the db mark 100 it means that the signal is far from the device, the closer you get the more the db goes down until it reaches zero.
You can adjust the sensitivity from 0 to 100
In this screen you can select the detection speed (Fast – Normal)
In this screen you will find all the information to use the MEFF M1-PRO APP correctly
In this screen you can manually adjust the sensitivity of signal detection
In this mode you can view the event history
Detector Mode 2
This mode has an innovative function, the possibility of detecting the distance in cm of the signal.
Our detector through a new patent is able to measure the distance, this is possible by combining and analyzing the various information received from the M1-PRO.
The distance is determined by the propagation time of the transmitted signal and by its power.
This function may be accurate or approximate depending on the signal strength, ambient noise or the type of transmitting device. As we know, not all devices and environments to be reclaimed are the same.
For a correct use of the function, it is recommended to first put the mobile
phone in use with APP in Airplane mode, turn off all known signals and then
start the measurement. The measurement takes place omnidirectionally, this
means that if the device indicates 60cm, it means that the signal is in an
omnidirectional radius of approximately 60cm from the position of the
detector.
In this mode you can also leave the device in monitoring and view the history
with the measurements in cm at a later time, this is very useful because you
can then go and look for signals in the indicated range. The system can give
two results:
Example:
- Distance: 20cm
- Distance between 20cm-40cm
To activate the function:
Click on DISTANCE
In this screen you will see the signal detected in cm shown.
You can adjust the sensitivity from 0 to 100
In this screen you can select the detection speed (Fast – Normal) In this screen you will find all the information to use the MEFF M1-PRO APP correctly In this mode you can view the event history with date and measurement in cm of the distance detected In this screen you can manually adjust the sensitivity of signal detection
