Bug Sweeping


Bug Sweeping

It’s surprisingly easy for almost anyone to cheaply acquire surveillance devices, or bugs, that can be used to invade your privacy. (TCSM) Technical Surveillance Countermeasures, or bug sweeps can help individuals and businesses protect their privacy. It is imperative to use a trained, qualified investigator. These services are there to detect bugs and uncover any illegal surveillance devices, any unknown technical surveillance devices, and any technical security weaknesses. Electronic surveillance detection is conducted to give you the peace of mind that your privacy is protected.

Common bugging devices:

Acoustic Bugs – A very basic listening device, Acoustic bugs are not electronic devices. They allow one to eavesdrop using a stethoscope, drinking glass, rubber tubes, or tape recorders in close proximity to the person speaking.

Ultrasonic or VHF Bugs -  These devices convert sound into an audio signal which cannot be heard by human ears, then intercept that sound wave and convert it back to audible frequencies to be recorded and listened to on the eavesdropper’s hardware.

Radio Frequency Bugs - These devices are the most common, using a transmitter to capture sounds and transport the audio signal to another location.

Optical Bug - These devices convert sounds into an optical pulse that can be transmitted and recorded.
