The frame rate will decrease if you select a higher resolution.
Intra Frame Period
Determine how often for firmware to plant an intra frame. The shorter the duration, the
more likely you will get better video quality, but at the cost of higher network bandwidth
consumption. Select the intra frame period from the following durations: 1/4 second,
1/2 second, 1 second, 2 seconds, 3 seconds, and 4 seconds.
Smart Codec Configuration
Dynamic Intra Frame Period
High quality motion codecs, such as H.265, utilize the redundancies between video
frames to deliver video streams at a balance of quality and bit rate. The encoding
parameters are summarized and illustrated below. The I-frames are completely self-
referential and they are largest in size. The P-frames are predicted frames. The encoder
refers to the previous I- or P-frames for redundant image information.
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.
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 Codec
Smart codec effectively reduces the quality of the whole or the non-interested areas on
a screen and therefore reduces the bandwidth consumed.
You can manually specify the video quality for the foreground and the background
areas.
