Radar technology uses radio waves to detect objects and determine their position, speed, and direction, providing reliable surveillance even in darkness, fog, or challenging weather where cameras may struggle. Unlike visual systems, radar minimizes false alarms by ignoring non-physical motion such as shadows or light changes, and includes built-in analytics for tracking and classifying objects like humans or vehicles. It also supports privacy-friendly monitoring since it does not capture identifiable images. Radar is often combined with cameras, thermal sensors, or audio systems to enhance detection and response, offering a complementary solution that improves accuracy, coverage, and overall system effectiveness.
