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 storage 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. average 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 Interval, 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

standard. 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. average 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 Interval, Prole and SVC are not congurable.

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 requirement for network bandwidth is also higher.

SVC

Scalable Video Coding (SVC) is the name for the Annex G extension of the H.264 or H.265 video

compression standard.
