Video Surveillance Mainstream Code Settings179

In the field of video surveillance, "mainstream code" refers to the video stream that provides the highest quality and resolution. This code is typically used for recording and playback. The mainstream code can be set to various resolutions, frame rates, and bitrates, depending on the capabilities of the camera and the desired level of detail.

When setting the mainstream code, it is important to consider the following factors:
Camera capabilities: The camera's maximum resolution and frame rate will determine the highest possible settings for the mainstream code.
Network bandwidth: The available bandwidth on the network will determine the maximum bitrate that can be used for the mainstream code.
Storage capacity: The storage capacity of the NVR or DVR will determine how long the mainstream code can be recorded for.
Desired level of detail: The higher the resolution and frame rate, the greater the level of detail in the video. However, this will also require more bandwidth and storage.

Once these factors have been considered, the following steps can be used to set the mainstream code:
Log into the camera's web interface.
Navigate to the "Video" or "Stream" settings page.
Select the "Mainstream" tab or option.
Set the desired resolution, frame rate, and bitrate.
Click "Apply" or "Save" to save the changes.

In addition to the mainstream code, many cameras also offer a "substream" code. The substream code is a lower-quality video stream that is typically used for live viewing or remote access. The substream code can be set to a lower resolution, frame rate, and bitrate than the mainstream code. This can help to reduce bandwidth consumption and improve performance on low-bandwidth networks.

When setting the substream code, it is important to consider the following factors:
Desired level of detail: The higher the resolution and frame rate, the greater the level of detail in the video. However, this will also require more bandwidth.
Available bandwidth: The available bandwidth on the network will determine the maximum bitrate that can be used for the substream code.
Performance requirements: The substream code should be set to a resolution and frame rate that provides acceptable performance for the intended use. For example, a substream code used for live viewing should be set to a frame rate that is high enough to provide smooth video.

Once these factors have been considered, the following steps can be used to set the substream code:
Log into the camera's web interface.
Navigate to the "Video" or "Stream" settings page.
Select the "Substream" tab or option.
Set the desired resolution, frame rate, and bitrate.
Click "Apply" or "Save" to save the changes.

By following these steps, you can ensure that the mainstream and substream codes are set to optimal values for your specific needs.
