Why do we need such high end hand held detection devices?

Searching for the illegal use of mobile / Cell signals is becoming an increasingly important task during counter surveillance sweeping. Numerous eavesdroppers transmit information via mobile/Cell 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 sound, video or location transmission. 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 to enable them to function on a cellular network. A GPS tracker is a device that is installed in a vehicle and transmits its location by sending coordinates via mobile communication.

The DD1217 is an unique hand held detection device: 

The user is able to see exactly which signal has been detected displayed right on the unit. This greatly improves the ability to distinguish suspicious signals from external interferences and enables the user to perform a physical search for a certain transmitter. Such ability is not available for wide-band detectors that combine all the signals. The iProtect 1217 has a selective detector, can inspect one separate band, which is why it is irreplaceable during professional searches. One more important advantage of the iProtect 1217 is the TRACKER mode (searching for GPS trackers). In this mode, the device is adjusted for detecting only mobile signals and accumulates a history of located periodic sending of data with coordinates. 

  • Able to detect mobile and wireless signals at a much greater distance compared to conventional RF detectors (at least 10 times more)

  • Selective: interference resistant and with a high sensitivity

  • Has worldwide coverage of mobile standards – can detect all existing bands of GSM, CDMA, 3G, 4G/LTE and 5G in the range up to 6 GHz

  • Detection of at least 26 mobile and wireless bands

  • Can be adjusted to the frequency allocation of the country of use

  • A selective multi-band principle of work informs the user of exactly which signals were found

  • The mode of analysis of a certain band facilitates the physical search of a transmitter

  • A separate mode for the detection of GPS trackers with history accumulation (TRACKER)

  • ALARM function warns the operator about exceeding the threshold, both with sound and visually

  • 43 threshold levels for setting optimal sensitivity

  • Can be set up for specific tasks, for example, for the detection of Wi-Fi only, etc.

  • Operation modes:  ALL BANDS (detection on all bands); GROUP (detection on the selected group of bands); BAND (analysis of a separate band); TRACKER (detection of GPS trackers)

  • Two antenna inputs and two antennas in the set for ensuring maximum sensitivity
