BANDS
Mobile communication (MBL1, MBL2, MBL3 and MBL4 groups)
The use of mobile communication has a number of advantages for covert surveillance:
1 Broadband channels enable transmission of high quality audio or video
2 There is no need to organize a control post near the surveillance object. The data
transmission is performed via the Internet. Recording into a cloud service is possible.
3 Remote control of the device is possible.
4 A convenient channel for transmitting the position of a vehicle (GPS trackers).
5 The possibility of information accumulation and a quick transmission according to a
schedule, or upon request.
6 The typical nature of the signal is a contributing factor for masking any surveillance.
Thanks to a wide coverage, unlimited distance and high quality of information transmission,
secret surveillance devices are using mobile communications increasingly frequently; while
the mass production of components for developers, such as GSM, 3G, 4G/LTE and 5G modules,
enable the development of cheap and quickly hidden bugging devices with high quality
The main types of the covert surveillance devices that use mobile communication:
A hidden wireless microphone
A hidden spy camera (possibly with a microphone)
An “infected” mobile telephone that transmits video and/or acoustics around itself
without its owner's knowledge
The deliberate use of a telephone for audio or video transmission
GPS trackers (beacons), which enable tracking of a car's coordinates
The iProtect 1217 can detect all types of secret surveillance devices which use mobile
communication and transmit a radio signal during a search.
Signals of DECT cordless phones (DECT group)
This standard was developed for cordless home phones. Most countries have an allocation for
its frequency band. The DECT standard has a high quality of sound transmission and an element
base available for the creation of a hidden spy device. It is possible to modify a household
appliance, for example, a baby monitor, for the purposes of covert surveillance.
The iProtect 1217 detects DECT signals which are active during a search.
ISM signals (ISM group)
ISM bands (Industrial, Science, Medicine) do not require licensing and are used by a number of
household and industrial appliances. The ISM group has the following bands:
433.05-434.79 MHz (Europe)
863-870 MHz (Europe)
902-928 MHz (the USA)
6
transmission of sound, video or location coordinates.
Remote controls, alarm sensors, Smart Home systems, various sensors, etc., function at these
frequencies. LoRa, DASH7, IEE 802.11ah, CC430, NB-IoT protocols and others are used.
