Spy gadgets are specialized tools designed for surveillance and intelligence gathering. They can include items like hidden cameras, listening devices, and GPS trackers. These gadgets help spies and law enforcement monitor activities discreetly and gather crucial information without being detected. Many spy gadgets are disguised as everyday objects, such as pens, glasses, or even smoke detectors. This concealment allows users to operate them in plain sight, making it harder for targets to notice they are being observed. Popular examples include James Bond gadgets and modern smartphone applications that enhance surveillance capabilities.
