Reducing the bit rate with Axis Zipstream

Dynamic FPS

With dynamic FPS, the camera captures and analyses video at full frame rate but before transmitting the data, unnecessary video frames are omitted from the stream. A static scene will be encoded with radically reduced frame rate. When changes occur in the scene, the frame rate is automatically increased to capture every important detail.
