Configuring Audio on Device

corresponding flag. The settings are applied right after Apply or OK are clicked.
It may be useful to go to Device's web page by clicking on the hyperlink. See "Configuring Proprietary Device
Parameters" for details.
Note: it is possible to configure audio for multiple devices at a time. See “Setting Same Parameters for Multiple
Devices”.
Configuring Device Authentication
All Devices come with a predefined login and password combination. During the discovery process, DW Spectrum
attempts to use manufacturer’s default credentials to access a device.
However, default login and passwords may vary between models/lines or can be changed deliberately, which prevents
DW Spectrum from accessing Devices and acquiring media streams. As a result, Device is shown as Unauthorized ( ) in
Resource Tree. The following message will appear if a user attempts to view a live stream:
UNAUTHORIZED
Please check authentication information in device settings.
Note: It is possible to configure Devices for Administrators and Viewers that have the appropriate permission
level.
To get Device working it is necessary to setup Authorization Parameters:
1. Open Device Settings -> General.
2. Enter Login and Password in the Authentication section and click Apply or OK. To discard changes, click Cancel.
Note: it is possible to configure same authentication credentials for several devices simultaneously. See “Setting
Same Parameters for Multiple Devices”.
Forcing Aspect Ratio for Cameras
Occasionally, Cameras report an incorrect Aspect Ratio. In such instance, DW Spectrum automatically corrects Aspect
Ratio for Cameras.
Note: this correction will require transcoding if exporting videos from Camera. See "Exporting Recorded Region
from Single Camera".
