Smartwatch-Based Hidden Camera Detection System for Women's Safety

Abstract The increasing misuse of hidden surveillance devices in public and semi-private spaces, particularly women’s washrooms and changing areas, poses a serious threat to personal privacy and safety. Conventional detection approaches, such as handheld RF scanners and mobile applications, are often inconvenient, expensive, or unsuitable for discreet operation. This paper presents a smartwatch-based hidden camera detection system designed to deliver immediate and unobtrusive alerts. The proposed system integrates radio frequency (RF) signal detection, infrared sensing, and magnetic field analysis to identify concealed surveillance devices. Upon entering a monitored environment, the smartwatch automatically scans the surroundings and provides visual and vibration alerts, using red indicators for unsafe conditions and green indicators for safe environments. The system emphasizes portability, ease of use, and continuous monitoring to offer both physical protection and psychological reassurance. Experimental evaluation demonstrates reliable detection performance, highlighting the potential of wearable technology to enhance women’s safety in everyday environments.
