Video Quality
When Bitrate Type is set as Variable, video quality is configurable. Select a video quality according to
actual needs. Note that higher video quality requires higher bandwidth.
Frame Rate
Frame rate describes the frequency at which the video stream is updated, measured in frames per second
(fps).
A higher frame rate is advantageous when there is movement in the video stream, as it maintains image
quality throughout. Note that higher frame rate requires higher bandwidth and larger storage space.
Video Encoding
This is the compression standard the device adopts for video encoding.
NOTE:
Available compression standards vary by model.
• H.264: Also known as MPEG-4 Part 10, Advanced Video Coding. This is a compression standard. Without
compressing image quality, it increases compression ratio and reduces the size of athe video file more
than MJPEG or MPEG-4 Part 2.
• H.264+: H.264+ is an improved compression coding technology based on H.264. By enabling H.264+,
you can estimate HDD consumption by its maximum average bitrate. Compared to H.264, H.264+
reduces storage by up to 50 percent with the same maximum bitrate in most scenes.
When H.264+ is enabled, Max. Average Bitrate is configurable. The device gives a recommended
maximum average bitrate by default. You can adjust the parameter to a higher value if the video quality
is less satisfactory. Maximum average bitrate should not be higher than maximum bitrate.
NOTE: When H.264+ is enabled, Video Quality, I Frame Interval, Profile and SVC are not configurable.
• H.265: Also known as High Efficiency Video Coding (HEVC) and MPEG-H Part 2. This is a compression
standard. In comparison to H.264, it offers better video compression at the same resolution, 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 estimate HDD consumption by its maximum average bitrate. Compared to H.265, H.265+
reduces storage by up to 50 percent with the same maximum bitrate in most scenes.
When H.265+ is enabled, Max. Average Bitrate is configurable. The device gives a recommended
maximum average bitrate by default. You can adjust the parameter to a higher value if the video quality
is less satisfactory. Maximum average bitrate should not be higher than maximum bitrate.
NOTE: When H.265+ is enabled, Video Quality, I Frame Interval, Profile, and SVC are not
configurable.
• MJPEG (M-JPEG or MJPEG): A video compression format in which intra-frame coding technology is used.
Images in MJPEG format is compressed as individual JPEG images.
