Which technology allows a camera to adjust based on scene activity?

The technology that allows a camera to adjust based on scene activity is Digital Dynamic Frame Rate, also known as DFPS. This technology enables the camera to monitor activity within the scene and dynamically adjust the frame rate based on the level of movement detected. When there is significant activity, the camera can increase the frame rate to capture more detail, resulting in smoother and clearer video. Conversely, during periods of low activity, the camera can lower the frame rate to save bandwidth and storage space, optimizing resource use without sacrificing video quality.

This ability to adaptively manage frame rates is particularly essential in surveillance applications, where activity levels can vary significantly, ensuring that critical details are captured when needed most while efficiently managing system resources. Other options such as Zipstream, Unicast, and Digital Video Recorders serve different purposes in video surveillance and do not provide the same dynamic adjustment capabilities based on scene activity.
