Counter Surveillance is the word used to describe the act of preventing or defending against surveillance. Covert surveillance has become easier and less expensive today due to the onslaught of easily obtainable technology that acts as bugs, taps, hidden cameras and other spy devices. The most popular method of counter surveillance is bug sweeping. Bug sweeping is the act of checking or sweeping as room with countermeasure tools such as Radio Frequency (RF) bug detectors and hidden camera detectors and other electronic sweep tools to search for surveillance devices such as hidden wireless cameras, wireless microphones, and GPS tracking devices to name a few.
RF detectors are one of the most commonly used device for electronic counter surveillance measures as they easily detect anything that is broadcasting an RF or radio signal. RF detectors detect radio frequency signals that come from wireless transmitting devices such as wireless cameras, GPS live trackers, and wireless microphones also called bugs. Everyday household devices also may be emitting RF signals such as wireless routers, Bluetooth headsets, Wi-Fi devices and cellphones. You may also find CB radios, walkie talkies and other common transmitting devices use RF signals to work. Be aware of this when using countermeasure tools during a sweep to avoid false positives.
A white noise generator is another popular device used in counter surveillance measures. This device emits an audible noise that will disrupt and cancel out hidden microphones that may be recording or broadcasting your conversations. White noise generators do not actually jam any signals and should not to be confused as an actual radio signal jamming device. Jamming devices are illegal in the USA and are not available for sale here.
Counter surveillance devices can provide you peace of mind as a new home owner, a new tenant in an apartment, suspect the lack of privacy in your hotel room, or if you are concerned that your office may have a surveillance device planted in it. These inexpensive do-it-yourself countermeasure tools work well and can locate bugs, taps and hidden cameras before you fall victim of electronic bugging.
