Protect 1207i by engineers or counterintelligence experts; It is a new measuring device that can be used safely for monitoring different digital transmissions such as GSM, Wi-Fi, Bluetooth. Today  New methods of “listening and watching” have become widespread with the help of modern technologies. For example, it is possible to buy a small GSM transmitter for only $100-200 at any internet spy shop, and with it all your conversations at home or in the office can be eavesdropped. Modern GPS Trackers use GSM and 3G cellular networks to transmit a car's GPS coordinates.

Most small hidden cameras use Wi-Fi to send video. Perhaps more importantly, the Bluetooth protocol is designed to transmit voice and speech in high quality up to 100 meters away, making it easy to use for insecticide.

The only way to safely detect wireless protocols is to use preselective chips (surface acoustic wave filter) that attenuate all other signals except the desired one. This is the Protect 1207i  built into it; It is a method that has 6 channels for different frequency ranges and can detect 6 different broadcasts simultaneously from a much longer distance than known RF detectors. These features make the Protect 1207i a highly desirable and reliable device during counterintelligence scans.


It is recommended to detect all sources of RF waves during a search. If it is a legitimate transmitter, such as a Wi-Fi access point, it is necessary to determine the nature of each source, or if it is from an unknown origin, it should be detected and possibly removed.

How to detect GPS trackers using Protect 1207i?


There are 2 methods of detecting GPS trackers using Protect 1207i:

1) GSM/3G outgoing broadcasts (uploads) from the  tracker to the mobile network while the vehicle is in motion  to detect

2) To detect the re-establishment of the connection between the monitor and the network connection after disconnection


Method 1

Protect 1207i can detect GPS trackers as they transmit their coordinates. Many trackers have a vibration sensor (G-sensor) and do not send coordinates when the car is not moving. Transmission can be made at a pre-programmed interval, for example every 15 seconds, 1 minute or 15 minutes. At the same time, a viewer may be uploading the collected coordinates with an external request, not starting the transmission by itself. That's why Method 2 is better, although it requires extra equipment.


  1. Make sure your own cell phones are turned off (either 'flight mode' is on or completely off) and there are no other phones in the car. If the car has its own GSM/3G phone or anti-theft alarm system, it is necessary to temporarily disable the phone or the alarm system by removing the SIM card.

  2. Place the Protect 1207i at the front of the vehicle and start moving the vehicle. If possible, choose a route away from highly populated areas (inside the country) to avoid accidentally measuring the GSM/3G signals of other people's mobile phones.

  3. Watch GSM and 3G bar graphs on Protect 1207i. Periodically increasing signals may be a sign of a monitor sending signals to the network. As mentioned above, the preprogrammed time interval inside the monitor is unknown, but must be the same during the measurement. For this reason, if you observe increments at constant intervals on the bar graph, it may be a sign of the presence of an audience.

  4. The vehicle must be moving during the measurements. For a 'quick' test a 30 minute test will suffice, for a 'deep search' drive for 1-2 hours looking at the detector

  5. Repeat the procedure with the Protect 1207i placed at the rear of the car without knowing which part of the vehicle the tracer is hidden in.


Method 2 (recommended)


This method is more reliable as trackers don't send "track" information, helping to detect them even if they're programmed to keep them in memory for future upload on demand. This method detects the GSM/3G modules built into the trackers, forcing them to communicate with the network. To implement this method, a portable GSM/3G jammer with an output power of not less than 1 Watt per frequency range (GSM900, GSM1800, 3G-not less than 3W in total) is needed. But higher power will give more reliable results.


The mobile network contains a number of LACs (location areas) that take up space. While the phone (or the GSM/3G module in the tracker) changes the LAC, the method re-registers in the tracker (location update). The size of the LAC may vary depending on the load on the mobile network, but if you are driving 10-15 km in one direction within the city, you will enter another LAC.


  1. Turn on the GSM/3G jammer inside your car and make sure it's working – your own phone must be out of signal ('no network' is displayed)

  2. Turn off all phones in the car ('flight mode' on or off completely). If the car has its own GSM/3G phone or anti-theft alarm system, it is necessary to temporarily disable the phone or the alarm system by removing the SIM card.

  3. Check the bar graphs of the Protect 1207i to check if the jammer is working (at full level)

  4. Drive towards another LAC (10-15 km away) and stop where there is no other phone (i.e. in an uncongested area)

  5. Turn the jammer off while viewing the Protect 1207i' bar graphs. Levels on the bar chart should drop immediately. If the graphs are at 1-3 second beats again after the drop, it means there is a GSM/3G device nearby. Such increases are a sign that there is an audience.

  6. For more reliable results, you can return to the starting point with the jammer turned on but by placing it elsewhere in the vehicle, for example behind it. When you arrive, place the 1207i in the back before turning on the jammer.


Before testing your vehicle for spectators, check that you are using the correct point of measurements and that there is another LAC in the area. Use your own phone, leave it on, drive with the jammer on, then turn off the jammer and check with the 1207i if your phone is communicating with the network (increment for 1-3 seconds).
