RAKSA iDet Selective RF Detector

RAKSA iDet Selective RF Detector can be used to detect and locate in near field a wide variety of radio transmitters used for secret access to information.

RAKSA iDet detects:

Cellular phones of GSM 850/ 900E/ 1800/ 1900, UMTS 850/ 900/ 1800/ 1900/ 2100, CDMA 450 (A-H)/ 800/ 1900 standards

Cordless DECT phones
Bluetooth and Wi-Fi devices
Wireless video cameras
Radio transmitters with analog modulation (AM, FM, PM)
Radio transmitters with digital modulation and continuous carrier (FSK, PSK, etc.)
Radio transmitters with wideband modulation up to 10 MHz bandwidth

RAKSA iDet is a superheterodyne receiver with low IF and frequency synthesizer. Scanning and analyzing cycle period is 1.0-1.5 sec. RAKSA iDet can operate within guard, sweep, search, difference search modes and monitoring of digital signals.

Competitive Advantages:

• Selective reception of radio signals

• High speed of scanning and analyzing

• Detection of wideband and digital signals

• Adaptation to the background noise in Guard Mode

• Difference search mode

• Audio monitoring

• Signal frequency and level measurement

• Alarm events log

• Soundless alarm indication (vibration mode)

• No need for external antenna

• Interface languages: English, German, Spanish, Italian, French, Russian

Technical Characteristics:

Detection range of radio signal source is determined by its radiated power and sensitivity of the field indicator. In cell phones radiated power depends on the reception conditions, such as distance from the base station, location inside or outside the building, etc. and can vary significantly. The typical values and limits of detection range of radio signal sources for the RAKSA iDet field indicator are as follows:

GSM cell phone: radiated power -20 - +30 dBm, detection range 0.3 - 80 m, typical value 10 - 20 m.

UMTS cell phone: radiated power -40 - +20 dBm, detection range 0.03 - 30 m, typical value 2 - 3 m.

DECT wireless phone: radiated power -20 dBm, detection range 8 m.

Wireless microphone for secret information retrieval : radiated power 0 - +10 dBm, detection range 3 - 10 m.

The limits of the transmitter power corresponding to the dynamic range of the RAKSA iDet field indicator are as follows:

at the distance of 1 m from the transmitter 0.15 mW - 15 W

at the distance of 3 m from the transmitter 1.4 mW - 140 W
