With the H.265 codec in an optimal scenario and when the Dynamic Intra frame and the Smart Stream

function are applied, an 80% of bandwidth saving can be achieved compared with using H.264 without

enabling these bandwidth-saving features.

Motions Occur.

By queuing the old frames from a static scene, both the computing efforts and the size of P frames are

reduced. It is beneficial for keeping up with the frame rate requirements.

A default frame difference threshold, 1%, is embedded in firmware 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.
