H.264+
H.264+ is an improved compression coding technology based on H.264. By enabling H.264+, you
can
esmate the HDD consumpon by its maximum average bitrate. Compared to H.264, H.264+
reduces storage by up to 50% with the same maximum bitrate in most scenes.
When H.264+ is enabled, Max. Average Bitrate is congurable. The device gives a recommended
max. average bitrate by default. You can adjust the parameter to a higher value if the video quality
is less
sasfactory. Max. average bitrate should not be higher than max. bitrate.
Note
When H.264+ is enabled, Video Quality, I Frame Interval, Prole and SVC are not congurable.
H.265
H.265, also known as High Eciency Video Coding (HEVC) and MPEG-H Part 2, is a compression
standard. In comparison to H.264, it oers beer video compression at the same resoluon, frame
rate and image quality.
H.265+
H.265+ is an improved compression coding technology based on H.265. By enabling H.265+, you
can esmate the HDD consumpon by its maximum average bitrate. Compared to H.265, H.265+
reduces storage by up to 50% with the same maximum bitrate in most scenes.
When H.265+ is enabled, Max. Average Bitrate is
congurable. The device gives a recommended
max. average bitrate by default. You can adjust the parameter to a higher value if the video quality

Note
When H.265+ is enabled, Video Quality, I Frame Interval, Prole and SVC are not congurable.
MJPEG
Moon JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding
technology is used. Images in a MJPEG format is compressed as individual JPEG images.

Prole
This funcon means that under the same bitrate, the more complex the prole is, the higher the
quality of the image is, and the requirement for network bandwidth is also higher.
