What is Motion Detection?
Motion detection is a camera or software feature that notices when something moves in the frame and reacts — starting recording, tagging the timeline or sending an alert. Basic detection compares consecutive frames and fires on any pixel change; smarter AI-based detection distinguishes a person or vehicle from a swaying branch, rain or a passing dog, drastically cutting false alarms.
Practically, motion detection converts continuous recording into an indexed timeline: instead of scrolling 24 hours of a godown camera, the owner reviews forty motion events in ten minutes. It also multiplies storage — recording only motion can stretch a hard disk from 15 days to months. For Indian shop owners, phone alerts on after-hours motion effectively turn a ₹1,500 camera into a basic alarm system.
