What is a common tool used for counter-surveillance operations to detect electronic bugs?

A bug detector is specifically designed for counter-surveillance operations and plays a crucial role in identifying electronic eavesdropping devices, also known as bugs. These devices can covertly transmit audio or video data, compromising privacy and security. Bug detectors operate by scanning a designated area for unusual radio frequency signals, electromagnetic emissions, or other indicators of surveillance technology.

In the realm of private investigation, employing a bug detector enables investigators to determine whether an area has been compromised by unwanted surveillance, allowing them to take appropriate action to protect client confidentiality or further the investigation without fear of being monitored.

The other tools listed do not serve the specific purpose of detecting electronic surveillance devices and are not equipped for that role. For example, a tripod is mainly used for stabilizing cameras or other equipment, a camera itself captures images or video rather than detecting hidden devices, and a flashlight is primarily for illumination, not for electronic detection.
