Network Camera User Manual
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, H265 or H265+ can be optional. If
H.265/H.265+ is chosen, make sure the client system is able to decode H.265/H.265+.
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.
Please check “Enable” as needed.
Audio Encoding
: G711A and G711U are selectable.
Audio Type
: LIN. LIN/MIC can be selected if the model supports built-in microphone.
Speaker
: Talkback or Warning can be optional. If “Talkback” is selected, the built-in speaker
will be used to output sound for two-way talk. If “Warning” is selected, the built-in speaker
will be used to output the pre-defined audio alarm.
