RAKSA iDet Selective RF Detector (Handheld Micro TSCM Device)
RAKSA iDet Selective RF Detector (Handheld Micro TSCM Device)
RAKSA iDet Selective RF Detector is a small and surprisingly powerful handheld transmitter detection device ideal for the detection and location of a wide variety of close proximity (near field) digital, analogue and wideband surveillance devices (audio and/or video bugs and transmitters).
“Whether used as a compliment to your sweep teams kit on a professional level or applied domestically, the Raksa iDet’s cost, size and proven capabilities make it a worthwhile addition to TSCM investigations and bug detection endevours “
Review and Application: Gerry Hall (Director of I.P.S and SECURITY SEARCH) comments: “The Raksa isn’t a primary piece of our counter surveillance arsenal but on review, we have found it to be extremely useful within our sweep teams: kitting out each of our operatives with a Raksa adds another simple but effective layer of detection possibilities. For example: Running a base level scan of a target room sets the parameters (frequency footprint), then, as investigations get underway and tests are made on appliances, cables, power decks, phones, computers, switches etc, if anything changes, or a frequency spikes (i.e: a device is activated or starts transmitting) then the Raksa will alert. Again this isn’t an OSCOR blue and there are obvious limitations but given the price and the competition, the Raksa is packed with clever tech that performs well.”

Monitoring Mode provides continuous monitoring of detected analog and digital radio signals in automatic mode and setting alarm in case of threat radio signal (signal exceeding the preset threshold level) detection. Monitoring Mode is used in cases when the primary signal source has not been activated. The information about the alarm events is recorded in the Alarm Log.
Monitoring Mode enables the background noise deduction for analog signals thus reducing the influence of regular background noise. Slow fluctuations of its level are ignored thanks to the adaptation algorithm.
Sweep Mode is used for detection of analog and digital radio signals of all types. This mode allows the review of all detected signals regardless their level.
Search Mode for analog signals utilizes both light and sound indication of the signal strength: the higher is the frequency of flash the closer is the transmitter.
Difference Search Mode
Difference Search Mode is used for detection and localization ofanalog transmitters. This mode has its advantage in case the transmitter is located in the same room.
In this Mode the device defines the relative level of the signal — its difference with the reference spectrum that was fixed at the beginning of operation in this Mode. The closer to the source of radio signal located in the room the higher is its signal level in comparison with the outside radio transmitter. The RF Detector selectively reacts to the change of level thus enabling to locate the radio transmitter at a higher rate.
Differential Search Mode utilizes both light and sound indication of the relative signal level.
Monitoring of Digital Signals
Monitoring of Digital Signals is intended for detection of mobile phone signals (GSM, UMTS(3G), CDMA types), cordless telephones (DECT standard), Bluetooth, Wi-Fi and other impulse signals in 2.4 GHz.
In Monitoring of Digital Signals the display shows the list of all digital signals and their strength levels.
Audio Monitoring is available only for analog signals in Sweep, Search and Difference Search Modes through the built-in speaker. The audio monitoring facilitates signal identification and allows using the acoustic feedback.
Alarm Events Log
Alarm Events Log accumulates the information about the threat signals detected in the Monitoring Mode. The max number of records – 200. If the detected threat signals are of different types the Log will record all of them. The display shows the moment of detection and the moment of the signal extinction, the type and the max level of the signal.

Radio transmitter detection requires two complimentary steps – search and guard. Search Mode enables to detect and locate the transmitters activated to the moment. Guard Mode provides continuous monitoring of the radio signals thus the transmitters are detected at the moment of their activation.
Before searching the target area all the radio signal sources should be switched off (mobile and cordless telephones, Bluetooth, Wi-Fi, microwave ovens). To activate the transmitters with voice control use any sound source.
Place the RF detector in the center of the room and switch on Search mode. Gradually approach the probable transmitter locations and watch the possible change of the signal level. Both light and sound indication can be used – the closer to the source of signal – the higher is the frequency of flashes. The high flash increase might indicate a hidden surveillance device.
After verification of the clean area change the mode to Guard and place RF Detector at your convenience. The RF Detector should stay stable to avoid false alarms. The alarm signal is generated when detection a threat radio signal.
The efficiency of radio signal detection in Guard Mode depends on correct setting of threshold levels. The mobile phones for instance are characterized by wide range of signal magnitude. Use the Digital Signals Monitoring Mode to define the signal levels of mobile and cordless phones, Bluetooth and the like and adjust the threshold level if necessary. The higher is the threshold level the less probable is false alarm but distance of detection will lessen as well.
