■ Dynamic Intra frame period
High quality motion codecs, such as H.265 or H.264, 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.

By dynamically prolonging the intervals for I-frames insertion to up to 10 seconds, the bit rates required
for streaming a video can be tremendously reduced. When streaming a video of a static scene,
the Dynamic Intra frame feature can save up to 53% of bandwidth. The amount of bandwidth thus
saved is also determined by the activities in the eld of view. If activities occur in the scene, rmware
automatically shortens the I-frame insertion intervals in order to maintain image quality. In the low light
or night conditions, the P-frames can have a larger size due to the noises, and hence the bandwidth
saving effect is also reduced.
Streaming a typical 2MP scene normally requires 3~4Mb/s of bandwidth. With the Dynamic Intra frame
function, the bandwidth for streaming a medium-trafc scene can be reduced to 2~3Mb/s, and during
the no-trafc period of time, down to 500kb/s.
