Eavesdropping Possibilities & Surveillance Technology<\/h1>\n

Types of Eavesdropping Technology
\nNew methods of “listening and watching” with the help of modern technologies are widespread in our time. For example, a tiny GSM transmitter can be purchased from practically any online spy shop for just 100-200 francs, and it can easily intercept all your conversations at the office or at home. Perhaps even more concerning is the Bluetooth protocol. It was specifically designed for high-quality voice transmission over distances of up to 100m and can be easily used for eavesdropping.<\/p>\n

Eavesdropping and Surveillance Technology Using Illegal Transmitters
\nHidden, compact, handcrafted, or produced in small quantities, these devices include microphones or video cameras implanted in other electronic devices, connected to telephone lines, integrated into AC wiring, or powered by their own power source, equipped with an antenna and\/or SIM card.<\/p>\n<\/div><\/div><\/div><\/div>

Reliably Detecting Illegal Transmitters
\nThe only reliable way to detect wireless protocols is by using pre-selector chips (SAW filters) that suppress all other signals except the desired ones. This is the method implemented at FocusControl, allowing 6 channels to scan different frequency ranges simultaneously and detect 6 different types of transmissions over much greater distances than common RF detectors. These capabilities make it a very desirable and reliable counter-surveillance tool.<\/p>\n

The sensitivity of common RF detectors (bug detectors) is spread over a wide frequency range, typically 3 or even 6-7 GHz. This means that standard detectors cannot recognize weak and non-continuous signals like Bluetooth, Wi-Fi, or Wi-Max. More powerful signals like GSM-1800 are also difficult to detect due to low sensitivity in higher frequency ranges.<\/p>\n

It is recommended that all sources of RF waves in the premises are identified during a search. It is necessary to determine the type of each source\u2014whether it is a regular transmitter like a Wi-Fi access point or has an unclear origin and should therefore be inspected and potentially removed.<\/p>\n
