A hidden camera, also known as a covert camera or spy camera, is a video or still camera used to record people without their knowledge. These cameras are typically disguised or concealed in everyday objects such as clocks, smoke detectors, or even clothing, in order to surreptitiously capture footage of individuals in private or sensitive situations. Hidden cameras are often used for surveillance, security, or investigative purposes, but their use is subject to legal and ethical considerations, as they can infringe upon individuals' privacy rights. Deploying hidden cameras without consent may be illegal in many jurisdictions, and it is important to carefully consider the legal and ethical implications before using such devices.
