More often than not, countersurveillance will employ a set of actions (countermeasures) that, when followed, reduce the risk of surveillance. Countersurveillance is different from

Sweeping is not foolproof. Advanced bugs can be remotely operated to switch on and off, and some may even rapidly switch frequencies according to a predetermined pattern in order to make location with sweepers more difficult. A bug that has run out of power may not show up during a sweep, which means

The timing of detection surveys and location scans is critical to success, and varies with the type of location being scanned. For permanent facilities, scans and surveys must take place during working hours to detect remotely switchable devices that are turned off during non-working hours to defeat

A method does exist to find hidden recorders, as these typically use a well known frequency for the clock which can never be totally shielded. A combination of existing techniques and resonance sweeps can often pick up even a defunct or "dead" bug in this way by measuring recent changes in the

Surveillance Countermeasures (TSCM) can best be defined as The systematic physical and electronic examination of a designated area by properly trained, qualified and equipped persons in an attempt to discover electronic eavesdropping devices, security hazards or security weaknesses.

Such activities make it harder to track surveillance subjects. Following steady, easy-to-predict schedules before employing aforementioned countermeasures may make the surveillance detail complacent and thus easier to lose.
