When bitrate type is selected as Variable, 6 levels of video quality are selectable.
Frame Rate:
Set the frame rate. The frame rate is to describe the frequency at which the video
stream is updated and it is measured by frames per second (fps). A higher frame
rate is advantageous when there is movement in the video stream, as it maintains
image quality throughout.
Max. Bitrate:
Set the max. bitrate from 32 to 16384 Kbps. The higher value corresponds to the
higher video quality, but the better bandwidth is required.
Note: The maximum limit of the max. bitrate value varies according to different
camera platforms. For certain cameras, the maximum limit is 8192 Kbps or 12288
Kbps.
Video Encoding:
The camera supports multiple video encodings types, such as H.264, H.265,
MJPEG, and MPEG4. Supported encoding type for different stream types may
differ. H.265 is a new encoding technology. Compared with H.264, it reduces the
transmission bitrate under the same resolution, frame rate and image quality.
Note: Selectable video encoding types may vary according to different camera
modes.
H.264+ and H.265+:
•
H.264+: If you set the main stream as the stream type, and H.264 as the video
encoding, you can see H.264+ available. H.264+ is an improved compression
coding technology based on H.264. By enabling H.264+, users can estimate
the HDD consumption 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.
•
H.265+: If you set the main stream as the stream type, and H.265 as the video
encoding, you can see H.265+ available. H.265+ is an improved compression
coding technology based on H.265. By enabling H.265+, users can estimate
the HDD consumption by its maximum average bitrate. Compared to H.265,
