Spy cameras, also known as hidden cameras or covert cameras, have been a staple in the realm of surveillance and espionage for decades. These tiny, discreet devices are designed to capture video or still images without detection, making them invaluable tools in various scenarios.

Spy cameras have come a long way since their inception. Originally, they were bulky and limited in functionality. Today, they are available in various forms, including everyday objects like pens, clocks, smoke detectors, and even clothing. The miniaturization of camera technology has played a significant role in their evolution, allowing for seamless integration into everyday items.
