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.

Motions Occur.
Comparing with Smart Stream II, Smart Stream III has two more configurable options: Smart Q, and
Smart FPS.
NOTE:
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.
■ Smart FPS
In a static scene, the algorithm puts old frames in queue when no motions occur in scene. When
motions occur, the encoding returns to normal to deliver real-time streaming.
