What is the purpose of motion detection in CCTV systems?

The purpose of motion detection in CCTV systems is primarily to enhance the system's efficiency and effectiveness in monitoring. When motion is detected within the camera's field of view, it triggers specific actions such as recording the event or sending alerts to the users. This feature allows for more targeted surveillance, as it ensures that only significant events, like movement, are captured and documented.

This capability is especially valuable in security applications, where the aim is to identify and respond to potential threats promptly. By focusing on motion activation, CCTV systems can conserve storage space and streamline the review process, allowing users to concentrate on the most pertinent footage instead of reviewing hours of continuous recordings.

While creating a visual record, adjusting the camera's focus, or preventing unauthorized access are important functions in some contexts, they do not directly relate to the primary role of motion detection within CCTV systems. Motion detection specifically concerns responding to physical movement, making it an essential feature for proactive monitoring and response.
