Maximum frame rate
This limits the maximum refresh frame rate per second. Set the frame rate higher for
smoother video quality and for recognizing moving objects in the field of view.
If the power line frequency is set to PAL, the frame rates are selectable from 1-50 fps. If the
power line frequency is set to NTSC, the frame rates are selectable from 1-60 fps. You can
also select Customized and manually enter a value.
The frame rate will decrease if you select a higher resolution.
Intra frame period
Determine how often for firmware to plant an I 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.

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.
