A/V Streams Tab
Use the A/V Streams tab to configure the video and audio streams for the camera. The A/V Streams tab includes a Video Presets page, a Video
Configuration page, and an Audio Configuration page.
Video Presets
The Video Preset page includes three fully-configured video presets, which include primary and secondary video stream settings for easy setup.
These presets may also be used as a starting point for a custom video configuration. These preset configurations vary depending on camera
model.
Video Configuration
The Video Configuration page allows you to customize the compression, resolution, image rate, and bit rate of the video streams. The default
names for the streams are Primary Stream and Secondary Stream. Although each stream can be configured independently, the settings of one
stream can limit the options available to the other stream, depending on the processing power used.
NOTE: Always configure the primary stream before the secondary stream. The primary stream should always be the most resource-intensive of
the streams.
Audio Configuration
The Audio Configuration page allows you to setup the internal audio device or an external audio device. The default setting for Audio is disabled,
which means that no audio is transmitted from the camera. When enabled, audio is transmitted from the camera to the PC. Based on your system
configuration, images and audio may not be synchronized.
Not all camera models are equipped with an internal audio device. Refer to the specifications for your camera model for information.
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 insuring strict compliance with such laws and for strict adherence to any/all rights of privacy and personalty.
