Camera settings : Configuring video profiles
 
Configuring video profiles
Video profiles define the video quality that you want the camera to capture and stream to the NVR. Note that the higher the video quality, the more bandwidth it consumes.
The video profiles will be used in the camera profiles. For details, see “Configuring camera profiles”.
To configure a video profile
1. Go to Camera > Configuration > Video Profile.
2. Click New.
3. Configure the following, then click Create.
Setting name
Description
Name
Type a name (such as live-stream1) that can be referenced by other parts of the configuration. Do not use spaces or special characters. The maximum length is 35 characters.
Resolution
Select the amount of detail (the number of pixels) in the image. from the dropdown menu.
Lower resolutions features less detail but are faster to transmit. Higher resolutions produce a clearer image but require more bandwidth. A higher resolution is preferable if the camera is recording a large space, such as a parking lot, where small details like faces and license plates could be important.
Note: Resolution greatly impacts performance, bandwidth, and the rate at which disk space is consumed. See “Video performance”.
Frames per second
Type the number of frames per second (FPS).
Conventional video is 24 frames per second. More frames per second may be useful if you need to record very fast motion, but increasing FPS will also increase disk usage and CPU usage.
Bit rate mode
Select the bit rate.
Variable — Automatically adjust the stream to the minimum bit rate required by the current video frames while maintaining video quality.
Fixed — Manually specify a constant bit rate in Bit rate. Specifying a bit rate that is too low may result in poor quality. Specifying a bit rate that is too high may needlessly consume extra bandwidth.
Bit rate
Type the bit rate that will be used.
This setting appears and is applicable only if Bit rate mode is Fixed.
Quality
Select the degree of compression.
Greater compression reduces required network bandwidth but causes greater CPU usage.
