compatible with your recording device(s) in order to ensure that your camera’s video stream can
be decoded and viewed.
l Main: An intermediate profile with a moderate compression ratio. This profile is compatible with
most recorders and uses fewer bits to compress video than the baseline profile. The main
profile supports I-frames, P-frames, and B-frames.
l High: A complex profile with a high compression ratio. This is the primary profile for high-
definition television applications. The high profile supports I-frames, P-frames, and B-frames.
l QoS (DSCP) Codepoint: A mechanism for prioritizing network traffic. This setting is available
with H.264 and H.265 compression standards. Your network must be QoS-aware to take
advantage of this setting.
l Endura Signing: Endura signing is a technology designed to prevent the tampering of video and
ensure video authenticity for use in legal proceedings. Only exported video is validated in the
Pelco export player when the user clicks on the "Authenticate" button. Live View is not
validated. This setting is available only with H.264 and MJPEG compression standards.
l Rate Control: Determines the bit rate and quality of each frame in the H.264 or H.265 video
stream. Rate control settings are a compromise between image quality and the resources
required for video storage. The availability of rate control settings depends upon the model of
the camera that you are using.
l CBR: The constant bit rate (CBR) streams video at a fixed number of bits per second. CBR
uses the full capacity of the bit rate setting for scenes with or without motion. Video is always
streamed at the user bit rate setting.
l CVBR: The constrained variable bit rate (CVBR) provides high-quality video and long recording
time of variable bit rate while limiting variations in recording capacity consumption.
Note
: When you change video stream configuration settings, the camera automatically
adjusts the bit rate. Choosing a bit rate below the camera’s automatic setting might
reduce video quality and limit stream configuration options.
Configuring Audio
You can only enable audio through the primary video stream.
Audio is disabled by default, but you can enable and configure audio streams from the Audio Configuration
page.
Audio and video might not be synchronized when viewing the primary stream through a Web browser. You
might experience up to a 3-second delay in video when viewing the primary stream with audio enabled.
Note: Improper use of audio/visual recording equipment may subject you to civil and criminal
penalties. Applicable laws regarding the use of such capabilities vary between jurisdictions and may
require, among other things, express written consent from the recorded subjects. You are solely
responsible for ensuring strict compliance with such laws and for strict adherence to any/all rights of
privacy and personality.
1. Place your mouse pointer over the A/V Streams tab, and select Audio Configuration.
2. Enable Audio.
3. Select your sample rate. The sample rate is the quality of the audio stream (measured in hertz per
second).
4. Select the encoding method (PCMU, PCMA, or PCM16 Encoding).
