Network Camera User Manual
I Frame interval
: It determines how many frames are allowed between a “group of pictures”.
When a new scene begins in a video, until that scene ends, the entire group of frames (or
pictures) can be considered as a group of pictures. If there is not much movement in the scene,
setting the value higher than the frame rate is fine, potentially resulting in less bandwidth
usage. However, if the value is set too high, and there is a high frequency of movement in the
video, there is a risk of frame skipping.
Video Compression:
MJPEG, H264+, H264, H264S (Smart H.264), H265, H265+ or H265S
(Smart H.265) can be optional. MJPEG is not available for main stream. If H.265/H.265+/
H.265S is chosen, make sure the client system is able to decode H.265/H.265+/ H.265S.
Compared to H.265+/H.265, smart H.265 can spontaneously adjust the bitrate distribution
according to the requirements of the actual scene. For example, when there is no human or
vehicle detected, the bitrate will be automatically reduced with no effect on image quality by
using H.265S. Compared to H.265, H.265+ saves more storage space with the same
maximum bitrate in most scenes. Compared to H.264, H.265 reduces the transmission bitrate
under the same resolution, frame rate and image quality.
Profile
: For H.264. Baseline, main and high profiles are selectable.
Send Snapshot
: Set the snapshot stream.
Video encode slice split
: If this function is enabled, smooth image can be gotten even though
using the low-performance PC.
Watermark
: When playing back the local recorded video in the search interface, the
watermark can be displayed. To enable it, check the watermark box and enter the watermark
text.
Click the “Audio” tab to go to the interface as shown below.
Audio Encoding
: G711A and G711U are selectable.
Audio Type
: LIN.
Speaker
: Choose warning voice or talkback as needed.
