Spy cameras are small, discreet devices used to capture video or images without the knowledge of those being recorded. They can be hidden in everyday objects like clocks, smoke detectors, or even toys, making them difficult to detect. These cameras are often used for security purposes, such as monitoring homes or businesses. In addition to security, spy cameras can also be used in various fields, including law enforcement and private investigations. However, the use of spy cameras raises ethical concerns regarding privacy and consent, leading to legal regulations in many areas to protect individuals' rights.
