Surveillance Countermeasures is the action taken to counteract a threat. AKA- counter surveillance Using a detector of some type would be considered countermeasures.
also known as listening device detectors or camera finders, are an efficient
way to determine if a wireless or wired listening device or “Bug” has been
used. Detecting a listening device or
locating a hidden camera is a simple process but requires patience and
attention to detail.
Camera detectors are designed to find hidden wired and wireless cameras. Again there are different devices that will accomplish this some units will perform many different searches and some are dedicated to a certain type of threat. Some will find the lens itself and some will locate the signal that the camera is using and some types provide a video feed.

A full “Sweep” can be preformed to locate all un-friendly devices this may be need to be done with multiple devices, depending on the threat level you face. Once you have determined that you have a threat you can decide how to proceed and with a detector that will solve your problem.
Generally, bug detectors all work the same way they look for “sweep” for wireless signals. A standard detector will find multiple signals but offers no filtering. A pro detector will allow you to search by frequency and spy device power.
It is a frightening
world out there and equipment to spy on you, collect personal information and
watch your every move is readily available.
Bug detectors will offer you a way to determine what and possibly who is listening in or watching your private life.
