Meanwhile, it provides comprehensive data and allows experienced professionals to analyse the signal in order to obtain detailed information and statistics useful for further analysis of the collected data.ĪDDITIONAL FEATURES OF THE PROFESSIONAL VIDEO SCANNER The Delta system and DigiScan EX software offer a user-friendly interface, easy to operate and requiring no specialist knowledge to use. After scanning the entire band, the operator can initiate the suspicious transmission source localisation procedure.Īpart from RF spectrum analysis, the professional video scanner to analyse the IR band and cable communications in search of intrusive signals – indicators of possible threat to privacy and danger of data leakage. This allows the DigiScan Delta 4G12G software to determine whether the source of the signal lies within or without the examined room. A signal received by an antenna located closer to the source will be much stronger than the one picked by an antenna situated farther away.

The basic principle of operation of counter-surveillance systems is the interdependence between the electromagnetic wave strength and the distance to its source – the former decreases proportionally to the increase in the latter. Scanning and detection procedure is fast and discreet, allowing to conduct room-by-room sweeps unobtrusively by placing the system in a room adjacent to the examined one.Īnalysing the data collected by two antennas allows to detect RF listening devices regardless of utilised modulation method and transmission encoding. Compared to conventional RF scanners commonly used for detection and localisation of listening devices, the digital receiver utilised by DigiScan Delta offers a much broader range of signal detection. Spectrum analysis technology utilised by DigiScan Delta 4G12G represents the highest professional level, which guarantees obtaining a complete set of information about any and all radio transmissions occurring in the examined area, without the necessity to relocate the device. The radio scanner analyses signals from 2 antennas simultaneously, allowing to detect all transmissions in the vicinity, regardless of the modulation type. It utilises a digital receiver and a spectrum analyser, which allows to sweep bands at 50MHz per second. Professional radio scanner for counter surveillance DigiScan Delta 4G12GĪ new counter-surveillance system, DigiScan Delta 4G12G allows to detect radio and infrared listening device transmitters in the frequency band of 4.4 / 12.4GHz.
