ABOUT THE DEVICE
Unfortunately, wide range RF detectors or near-field receivers have a low sensitivity and
are not very suitable for the detection of mobile devices. This is caused by the ability of the RF
detectors to receive all signals simultaneously and display them cumulatively on a bargraph,
and as a result, stronger signals prevent the detection of weaker ones.
Selective detectors have a much greater distance of detecting mobile signals because
they only accept them, and ignore other frequencies. Unfortunately, during the development of
a selective detector, one nuance appears. It is very difficult to create a detector able to receive
all mobile bands at the same time. As is well known, more and more mobile bands are being
used worldwide. The GSM standard works on two bands. Then 3G appeared, occupying one
more band. The introduction of the 4G/LTE standard required a wider frequency spectrum for
functioning; therefore 3-7 frequency bands were allocated for it in each country. Later still 5G
appeared, which requires an even wider spectrum so more wide bands have been allocated for
its functioning. Thus, currently, in most countries, there are up to 10-15 different frequency
It is very difficult to create a selective detector which is able to detect signals from all
mobile bands which will work in all countries. Thankfully, the designers of the iProtect 1217
have achieved this. The iProtect 1217 is the only detector in the world which is able to detect
all the existing mobile standards on all continents. Its table includes at least 26 bands, which
can be selected automatically or manually.
In addition to mobile communication, the 1217 detects signals of Wi-Fi, Bluetooth, DECT,
ISM 434 MHz, ISM 868 MHz and ISM 915 MHz. It is well known that these standards can be
used by hidden surveillance devices for audio and video signal transmission, and therefore such
transmitters must be found and identified.
Searching for the illegal use of mobile signals is becoming an increasingly important task
during counter surveillance sweeping. It is connected with the numerous means of eaves-
dropping that transmit information via mobile networks. The mass production of components
for developers, such as GSM, 3G, 4G/LTE and 5G modules, enables them to develop cheap and
quick surveillance methods which have ultra-high quality of sound, video or location trans-
mission. Hidden cameras camouflaged as household appliances, toys or interior objects, will
most likely transmit data via mobile networks or Wi-Fi. Spy listening devices quite often have a
slot for SIM-cards for functioning on a cellular network. A GPS tracker is a device that is
installed in a vehicle and informs about its location, these also send coordinates via mobile
communication.
