With the H.265 codec in an optimal scenario and when Dynamic Intra frame is combined with
the Smart Stream function, an 80% of bandwidth saving can be achieved compared with using
H.264 without enabling these bandwidth-saving features.
■ Smart FPS
In a static scene, the algorithm re-encodes old frames when no motions occur in scene. When
motions occur, the encoding returns to normal to deliver real-time streaming.

By queuing the old frames from a static scene, both the computing efforts and the size of P
frames are reduced. It is benecial for keeping up with the frame rate requirements.
A default frame difference threshold, 1%, is embedded in rmware for returning from Smart FPS
to normal encoding when motions occur.
