Configuring video profiles
Video profiles define the video quality that you want cameras to use when they record or stream live video to FortiRecorder. If you want to use a factory default profile (for example, high-resolution), then you can skip this step during initial setup. Otherwise you can configure profiles with your custom settings.
Video profiles are used in camera profiles. For details, see Configuring camera profiles.

Better video quality consumes more network bandwidth and more disk space. If you need to retain video for a long time, or have a slow network, then you might need to reduce the video quality until you reach acceptable network performance or disk usage. |
To configure a video profile
- Go to Camera > Configuration > Video Profile.
- Click New.

Configure the following settings:
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.Select the video compression format, such as H.264 AVC or H.265 HEVC.
Select the amount of detail (the number of pixels) in the image. from the drop-down menu.
Lower resolutions have 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.
High resolution can significantly reduce performance and increase network bandwidth and disk space usage.
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 space usage and CPU usage.
Select from the drop-down menu the duration of a group of pictures (GOP) sequence. A GOP sequence is the interval between frames that contain the full image. Longer intervals save bandwidth, but slightly delay the start of live video streams.
Select the bit rate:
- Variable — Automatically adjust the stream to the minimum bit rate required by the current video frames while maintaining video quality. In variable bitrate mode the camera lowers the bitrate dynamically when little motion is present. This setting increases the presence of noise.
- Fixed — Manually specify a constant bit rate in Bit rate. In fixed bitrate mode the camera attempts to keep the bitrate constant at the configured level. This guarantees calculated video retention time and bandwidth but might reduce image quality if. for example, if there is a sudden burst of motion, like rain or flashing lights.
- Constrained — Automatically adjusts the stream to lower the bitrate usage during periods of low activity, while enabling the ability to set the maximum bitrate the camera can stream.
Enter the maximum bitrate that the camera can stream. Lower bitrates use less bandwidth by sacrificing image quality.
This setting is only available when Bitrate mode is Constrained.
Select the degree of compression.
Greater compression reduces required network bandwidth but causes greater CPU usage.
Enable or disable audio.
