What does the term 'motion detection' imply in CCTV usage?

The term 'motion detection' in the context of CCTV usage refers specifically to the system's ability to capture video footage only when movement is detected within its monitoring area. This technology significantly optimizes recording by ensuring that storage space is utilized efficiently, as it avoids continuous recording when no activity is present.

By enabling the cameras to trigger recording based on detected motion, users can save time when reviewing footage, as they will only need to analyze segments where movement has taken place. This functionality is particularly beneficial in security applications, where monitoring activity is crucial, as it allows for a more focused review of events and can alert users to potential incidents as they occur.

The other options do not accurately describe the functionality of motion detection in CCTV systems. Continuous recording regardless of activity does not utilize motion detection, while enhanced night vision capabilities and features that increase storage capacity are unrelated to motion detection specifically.
