Lower frequency, better detection [DSEI17D1]

12 September 2017

Research Electronics International (REI, Stand N5-334), a leader in technical security equipment to protect against illicit information theft and corporate espionage, is presenting the new ORION 900 HX Non-Linear Junction Detector (NLJD), which detects electronic semi-conductor components through dense materials such as bricks, concrete and soil.

The longer 900MHz wavelength is said to be better at detecting older, less refined circuitry and also at penetrating building and construction materials, than the shorter wavelength of the 2.4GHz model.

The ORION antenna head is a transceiver that radiates a 1.25MHz-wide digital spread spectrum signal to determine the presence of electronic components. When the signal encounters semi-conductor junctions (diodes, transistors, circuit board connections, etc), a harmonic signal returns to the receiver, which measures the strength of the harmonic signal and distinguishes between first or third harmonics. When a stronger second harmonic signal is present, visual, audio and haptic feedback alerts on the ORION notify users that a junction has been detected. In this way, the hand-held ORION 900 HX is used to sweep walls, objects, containers, furniture and most surfaces to look for hidden electronics, regardless of whether they are turned on.

For those looking to equip themselves for every situation, ORION HX Deluxe is available, which has 900MHz and 2.4GHz antenna heads exchanged by simply turning a pair of thumbscrews. The touchscreen controller on the ORION handle automatically recognises the attached antenna and displays the corresponding data.

Another new product is the TALAN 3.0 telephone and line analyser, which offers advanced VoIP and shielded/earth/ ground cable tests to detect and locate illicit devices.
