The scanner can also be coupled to a down converter antenna so as to cover the widest frequency range possible.
Top of the range frequency scanners can also be connected to the mains reticulation system to detect the presence of mains carrier bugs. These bugs transmit information along the mains supply and since they do not transmit any form of radio frequency, they are invisible to standard frequency scanners.
Spectrum analyser- an instrument that resembles an oscilloscope but that has the ability of visually representing high frequency transmissions as waveforms on a screen. This also allows the visualisation of “burst” transmissions that would not ordinarily be picked up on a frequency scanner.
Non linear junction detector (superbroom) - this instrument is used to physically locate the presence of any electronic device by locating the presence of semiconductor components found in all electronic devices. The NLJD emits harmonic waveforms which are disrupted by the presence of these semiconductors (non-linear junctions). The NLJD can therefore also detect such equipment with flat batteries or even switched off. The colloquial term of “superbroom” is attributed to the shape of the device.
Often, the only practical means of gathering intelligence is to monitor conversations. Justicia’s intelligence gathering department has a variety of microphones, transmitters and telephone bugs to achieve this.
People are often concerned about using such methods to combat irregular activities within their businesses, but if done properly within certain parameters, then it is perfectly legal to do so.
Justicia’s intelligence gathering department will ensure a professional installation of such devices and guide the client through all the legalities of applying such technologies. Justicia investigators will follow through with the process and even lead evidence in court if necessary.
Part of an international viewpoint to bugging is that “an employer’s right to protect his legitimate business interests outweigh the employee’s right to privacy”.
Expressed another way, the South African judges are saying “…telephonic conversations of the employee relating to the employer’s affairs are not private and are not protected under the constitution…”
Of course, given the legal minefield surrounding this issue, one can appreciate the importance of engaging the services of a reputable investigations company that will ensure that all the legal aspects of applying such technologies are considered with the view to a successful result.
