A hidden camera is a device designed to record video or audio without the knowledge of the people being observed. These cameras are often small and discreet, allowing them to be placed in various locations, such as homes, offices, or public spaces. They can be used for security purposes, monitoring activities, or capturing events without drawing attention. Hidden cameras can be part of a larger surveillance system or operate independently. They may connect to a Wi-Fi network for remote viewing or store footage on a memory card. While they can serve legitimate purposes, their use raises ethical and legal concerns regarding privacy.
