Digital Wideband RF & GSM/ 3G Detector (1MHz – 10GHz)

Product number: PKI 4100

PKI 4100 Digital Wideband RF & GSM/ 3G Detector (1MHz – 10GHz) is an intelligent compact handheld counter surveillance device designed to detect and locate the presence of covert surveillance devices. The PKI 4100 has got two independent RF detectors, one that detects a Wideband range of 0 to 10.000MHz (10GHz) and another which detects only the Cellular GSM900, GSM1800 and 3G (UMTS) bands with much increased sensitivity. These two independent detectors can operate simultaneously for maximum detection capability or separately to allow specific types of devices to be detected or filtered.

Our latest digital RF and microprocessor technology is utilized to provide very high sensitivity across a wide frequency range to ensure detection and location of even the weakest radio transmissions. The Wideband 1MHz – 10GHz mode is used to detect VHF, UHF and Microwave transmitters. Such devices include miniature room transmitters or bugs, main powered transmitters, telephone transmitters, video transmitters, mobile telephones, fixed frequency tracking devices, walkie talkies etc.

The Cellular GSM & 3G mode is used to detect transmissions from cellular mobile phone based devices. Such devices include mobile phones, GPD vehicle trackers, GSM listening devices (bugs) and convert wireless 3G cameras. With the Digital Peak Pulse mode, which is used to detect signals from devices that only transmit momentarily and to indicate that a signal has been detected. Such devices include vehicle trackers, GSM devices with SMS text messages or burst transmitters that accumulate information and transmit it in short bursts.
