Auto Discovery

In order for the Auto-Discovery feature to work, your network must have Multicast communication enabled. 

The DW Spectrum Server software initiates a continuous sequence of requests to try to get all of the devices (sharing the same network setup) to respond back to the Server with detailed information on what methods to use in order to add them to the video management system.

Added devices will appear in the Resource Tree under the server it was associated with.

Note:  If you disable the Auto-Discovery feature, devices must be added to DW Spectrum manually.  Please read Adding Devices Manually To DW Spectrum for more information.

• DW Blackjack Series

Additional Information

In addition to continuously discovering new cameras and Servers, the DW Spectrum Server software also sends discovery requests for status updates from pre-existing cameras (previously added).

In order to free up network resources, the number of transactions between servers and devices are minimized.  As a result, both manually added and auto-discovered devices will be shown as offline unless anything below is true:

• Auto-discovery is enabled
• Camera stream is currently being monitored/viewed
• DW Spectrum is archiving camera recording
• Camera stream was viewed or recorded prior to disabling Auto-Discovery
• Failover is enabled
