Motion detection is a technology that identifies movement or changes within a monitored area using cameras, sensors, or other devices. It compares incoming visual or sensor data with previous information to determine whether something has moved. In AI-based systems, computer vision models can analyze video frames and distinguish relevant movement from background changes, enabling automated responses.
For example, a smart security camera can detect a person approaching a restricted entrance and trigger an alert. This helps improve security, reduce the need for constant human monitoring, and enable faster responses to events. Motion detection is widely used in surveillance, smart homes, industrial safety, traffic monitoring, and automated systems.
