TSCM (technical surveillance counter-measures) or more commonly known as electronic bug sweep is to counter-measure any professional attack from a electronic surveillance device including covert listening devices, covert visual surveillance and now cyber surveillance where buggist will use software and hardware tools to access computing and mobile devices.
Most bugs transmit information, whether data, video, or voice, through the air by using radio waves The standard counter-measure for listening devices of this nature is to search for such an attack with a radio frequency receiver, looking for the radio emissions. This first stage of the bug sweep, not foolproof. Advanced bugs can be remotely operated to switch on and off, and some even rapidly switch frequencies according to a predetermined pattern to make location with receivers more difficult.
A bug that has run out of power also will not show up during a sweep and other types that Instead of transmitting conversations, may record them. Bugs that do not emit radio waves are complicated to detect, which means that the receiver operator will not be alerted to the surveillance. Though there are several options for detecting such bugs.
We at Mias TSCM would then use stage two of our sweep and use non-linear junction detectors this equipment will enable the operator to find electronic devices even when switched off, or the battery has been used up we would also the use of sensitive equipment that could be used to look for magnetic fields. Another method is using thermal imaging cameras to detect residual heat of a bug, or power supply, that may be concealed in a wall or ceiling. The device is found by locating a hot spot the device generates heat hermal camera can then detect that.
