H.264+
H.264+ is an improved compression coding technology based on H.264. By enabling H.264+, you
can esmate the HDD consumpon by its maximum average bitrate. Compared to H.264, H.264+
reduces s
torage by up to 50% with the same maximum bitrate in most scenes.
When H.264+ is enabled, Max. Average Bitrate is congurable. The device gives a recommended
max. a
verage bitrate by default. You can adjust the parameter to a higher value if the video quality
is less sasfactory. Max. average bitrate should not be higher than max. bitrate.
Note
When H.264+ is enabled, Video Quality, I Frame In
terval, Prole and SVC are not congurable.
H.265
H.265, also known as High Eciency Video Coding (HEVC) and MPEG-H Part 2, is a compression
st
andard. In comparison to H.264, it oers beer video compression at the same resoluon, 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 esmate the HDD consumpon 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 congurable. The device gives a recommended
max. a
verage bitrate by default. You can adjust the parameter to a higher value if the video quality
is less sasfactory. Max. average bitrate should not be higher than max. bitrate.
Note
When H.265+ is enabled, Video Quality, I Frame In
terval, Prole and SVC are not congurable.
MJPEG
Moon JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding
technology is used. Imag
es in a MJPEG format is compressed as individual JPEG images.
9.1.8 Prole
This funcon means that under the same bitrate, the more complex the prole is, the higher the
quality of the image is, and the r
equirement for network bandwidth is also higher.
