Tab Parameter descriptions
Resolution: Specifies the recording resolution. A higher image resolution
provides a higher image quality but also requires a higher bit rate. The
resolution options listed depend on the type of camera and on whether main
or sub stream is being used.
Note: Resolutions can vary depending on the camera model.
Bitrate Type: Specifies whether variable or fixed bit rate is used. Variable
produces higher quality results suitable for video downloads and streaming.
Default is Constant.
Video Quality: Specifies the quality level of the image. It can be set when
variable bit rate is selected. Options include: Lowest, Lower, Medium, Higher
and Highest.
Frame Rate: Specifies the frame rate for the selected resolution.
The frame rate is the number of video frames that are shown or sent per
second.
Note: The maximum frame rate depends on the camera model and selected
resolution. Please check the camera specifications on its datasheet.
Max bit rate: Specifies the maximum allowed bit rate. To maintain image
quality for high image resolution, a high bit rate must also be selected.
Video Encoding: Specifies the video encoding used.
Profile: Different profile options indicate different tools and technologies used
in compression. Options include: High Profile, Main Profile and Basic Profile.
I Frame Interval: A video compression method. It is strongly recommended
not to change the default value 50.
SVC: 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: Adjust the smoothness of the stream. This setting allows for
balancing of fluid movement with sharpness of resolution.
2. Audio Audio Encoding: G.722.1, G.711ulaw, G.711alaw, MP2L2, G.726 and PCM
are optional.
Audio Input: Select "LineIn" or "MicIn"
Input Volume: Specifies the volume from 0 to 100.
Environmental Noise Filter: Set it as OFF or ON. Enable the function to
filter background ambient noise.
3. ROI Enable to assign more encoding resources to the region of interest to
increase the quality of the ROI whereas the background information is less
focused when network performance is less than optimal.
4. Display Info. When Dual-VCA mode is enabled, the camera sends video analytics results
On Stream (metadata) to an NVR or other platforms to generate a VCA alarm.
5. Target You can specify a target area on the live video, and then the specified video
Cropping area can be displayed via the third stream in certain resolution, providing
more details of the target area if needed.
