Before Starting

  • DW Witness™ is compatible with DW Spectrum IPVMS v3.2 or higher
  • TCP Port 7001 and TCP Port 32201 should be port forwarded for external network use
  • If using a network Firewall or SonicWall, TCP Port 7001 and TCP Port 32201 must be port forwarded

Using DW Witness™ With DW Spectrum®

If the DW Witness™ camera does not display in the Device List after one minute, Stop then Start the DW Spectrum® Server.

If a “No Signal” message displays, click on the Diagnostics button at the bottom of the viewing window.  Alternatively, you may wait a moment to see if a connection is established.

  1. You may set the recording settings for the DW Witness™ device like any other camera.

  • For Motion recording, open Camera Settings, then select the Expert tab.  Under the Motion Detection section, enable Force motion detection for stream, then select Primary from the drop-down menu.
