TSCM (Technical Surveillance Counter Measures)

Below is a brief summary of some of the equipment currently in use by Crystal Communications Ltd.

Scanlock M2 - Radio Bug Detection System

Scanlock M2 can scan the RF spectrum in a fraction of the time taken by conventional counter surveillance receivers. Integral audio demodulators aid the identification of any signal acquired. Computer enhanced spectral analysis aids the identification of all types of active RF transmitter. Lighter and more portable, Scanlock M2 makes the pinpoint location of RF transmitters swift and silent. All cables, including mains and telephone, can be checked for current carrier or RF transmitters using the Scanlock M2's full range of facilities.

Technical Features:

Rapid signal Detection
Identification of all signal types
Device location
Automatic tuning mode
Cable checking
Scan rates under 5 seconds
DC to above 5Ghz1
Sensitivity better than -70Bm2

Spectrum Analyzer

The sprecturm analyser is used to analyse the electro-magnetic spectrum to determine if there are any transmitting devices that are currently transmitting from the premises under inspection.

At a minimum for a low-threat inspection, the spectrum analyser should be capable of analysing frequencies from 1Mhz up to 5Ghz (5000Mhz). The spectrum analysers we use are capable of searching from below 1Mhz up to 5Ghz. You may find that many firms have equipment that can only reach around 2Ghz. Although this may be adequate for some low-level sweeps, there are now many video and audio transmitters on the public market that transmit at 2.4Ghz and upwards.

Super Wide Band Antenna

The importance of the antenna cannot be overstated. This is the ear of the RF system. No amount of signal processing can analyse a signal not captured in the first instance. Using the antenna with Scanlock M2 and Spectrum Analysers enables us to detect weak signals.
Model: WB-2000 Dimensions: 650 x 600 x 40mm Bandwidth approx equal to half wave dipole: 150-4300Mhz Usable bandwidth: 70Mhz - 5Gz+ VSWR: 2:1 Bandwidth/Polarisation: 120 degrees/Circular Weight: 5.5Kg

Non Linear Junction Detector (NLJD)

The NLJD can be used to locate transmitters, tape recorders, phone taps and video equipment.

The NLJD can detect these devices whether they are operating or not. It works by detecting the electronics components that are within the bugging device.

The use of an NLJD is important because some bugging devices can be activated by remote control or by a timing device and may not be operating at the time of the sweep. Due to the cost of an NLJD, many firms do not use them.
