Video Encoding : If the Stream Type is set to main stream, H.264 and H.265 are selectable. If the stream type is set to
sub-stream or third-stream, H.264, MJPEG, and H.265 are selectable. H.265 is a newer encoding technology that 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+ : If you set the main stream as the stream type, and H.264 as the video encoding, H.264+ is also 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, H.265+ is also 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, H.265+ reduces storage by up to 50% with the
same maximum bitrate in most scenes.
NOTE
After you change the compression mode, you must reboot the camera for the mode to be used.
Upgrade your video player to the latest version if live view or playback does not work properly due to compatibility.
To use to use H.264+ or H.265+, the bitrate type selected must be
Variable .
With H.264+/H.265+ enabled, the parameters such as profile, I frame interval, video quality, and SVC are greyed out when the bitrate
type is variable.
With H.264+/H.265+ enabled, some functions are not supported. For those functions, corresponding menus will be hidden.
H.264+/H.265+ can spontaneously adjust the bitrate distribution according the requirements of the actual scene in order to realize the set
maximum average bitrate in the long term. The camera needs at least 3 days to adapt to a fixed monitoring scene.
—
Max. Average Bitrate : When you set a maximum bitrate, its corresponding recommended maximum average bitrate
will be shown in the Max. Average Bitrate box. You can also set the maximum average bitrate manually from 32 Kbps to
the value of the set maximum bitrate.
—
Profile : Basic profile, Main Profile, and High Profile for coding are selectable.
—
I Frame Interva l: Set I Frame Interval from 1 to 400.
—
SVC : Scalable Video Coding is an extension of the H.264/AVC standard. Select OFF/ON to disable/enable the SVC function.
Select Auto and the device will automatically extract frames from the original video when the network bandwidth is
insufficient.
—
Smoothing : It refers to the smoothness of the stream. The higher value of the smoothing is, the better fluency of the
stream will be, though, the video quality may not be so satisfactory. The lower value of the smoothing is, the higher
quality of the stream will be, though it may appear not fluent.
—
Display VCA Info By : Select the display media as Player or Video. Player means the VCA info can displayed only with the
VS player. Video means the VCA info can displayed by any general video player.
