The Protect 1206i is a new class of counter surveillance device. Unlike all typical searching devices it can detect modern 'hidden' bugs which use such protocols as Bluetooth and Wi-Fi at a long distance. Such bugs, especially Bluetooth types, are practically undetectable by common RF detectors due to their very low transmitted power and special type of modulation. The i Protect DD1206 uses a separate channel with a high, (2.4/5 GНz) frequency pre-selector to detect and locate Bluetooth and Wi-Fi with a much higher sensitivity. The unit also then processes the demodulated signal in order to identify which protocol has been detected. In addition the unit can detect all 'classical' bugs and inspect them for the presence of correlation by sending sound impulses as well as other digital transmissions at a standard distance (GSM, 3G, DECT, etc.) The DD1206 is a sophisticated handheld radio frequency detection device that incorporates the ability to detect nearly any type of wireless protocol including digital frequencies such as Wi-Fi and analog frequencies reaching up to 12Ghz in range. Making this detection device extremely successful at finding unwanted surveillance threats are the two different antennas users can deploy and the demodulation feature which enables the users to hear the sound signature of the frequency.
