Network Camera User Manual
no matter how much change is seen in the video scene, the compression bitrate will be kept
constant. VBR means that the compression bitrate will be adjusted according to scene changes.
For example, for scenes that do not have much movement, the bitrate will be kept at a lower
value. This can help optimize the network bandwidth usage.
Bitrate: it can be adjusted when the mode is set to CBR. The higher the bitrate, the better the
image quality will be.
Video Quality: It can be adjusted when the mode is set to VBR. The higher the image quality,
the more bitrate will be required.
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 mainstream. 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: How many snapshots to generate for an event.
Video encode slice split: If this function is enabled, smooth image can be received even
though using a 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.
Audio Encoding: G711A and G711U are selectable.
Audio Type: LIN. MIC can be optional for the model with built-in MIC.
