Compressor Communication

The Digital Watchdog Compressor™ (DW-CPUHD16) uses H.264 compression in the communication of camera video to various recorders and receivers.  By allowing video frames to be inserted between I-Frames, the information required to represent a video stream is reduced.

In addition, the use of a Compressor™ translates analog camera video to an IP network, allowing users to add analog camera streams to an NVR server.

Identification Issues

When adding a Compressor™ to DW Spectrum®, the device might show that it was added to the DW Spectrum® Server as a VMAX recording model. 

A common cause of this issue is how the Server identifies the Compressor™ when the device is automatically or manually to DW Spectrum®.

This guide will explain how to re-add the Compressor™ to DW Spectrum® using the Auto Discovery feature, as well as how to re-add the Compressor™ manually.

Supported/Affected Devices

  • DW Compressor™ Series
  • DW Blackjack® Series

Re-Adding Through Auto Discovery

This method will explain how to delete and re-add the Compressor™ using the Auto Discovery feature of DW Spectrum®.

  1. At the Server, launch the DW Spectrum® IPVMS Client and log into the Server as an Administrator.
    • Default ID:  admin
    • Default Password:  admin12345
  1. Open the System Administration menu.

  1. Enable and apply the Auto Discovery setting.

  1. Right-click on the device in the Resources List, then Delete it from the Server.

  1. Allow the Server a moment to discover and re-add the Compressor™ automatically.

The device should be re-added correctly.

  1. If re-added Compressor™ shows that there is an authorization issue, right-click on the Compressor™ in the Resources List, then select Camera Settings.

Ensure that the Login and Password matches the ID and Password login that is used for the Compressor™ (Default:  admin / --- (blank)).

Make any necessary changes, then apply the settings.  If the authorization issue persists following the changes, close and re-launch the DW Spectrum® Client.

DW Spectrum® should now identify the Compressor™ correctly and allow users to monitor video streams from the analog cameras.

Re-apply any Recording Licenses to the Compressor’s cameras as necessary.

Re-Adding Manually

This method will explain how to delete and re-add the Compressor™ manually to DW Spectrum®.

  1. At the Server, launch the DW Spectrum® IPVMS Client and log into the Server as an Administrator.
    • Default ID:  admin
    • Default Password:  admin12345
  1. Right-click on the device in the Resource List and select Camera Settings.

Take note of the Compressor’s IP Address, then close the Camera Settings menu.

**NOTE:  Following images may vary from your settings.  In this example, the IP Address is 192.168.100.131, using Port 80.

  1. If you know the Compressor’s IP Address, right-click on the Compressor™ in the Resources List, then select Delete.

  1. Right-click on the Server in the Resources List, then select Add Device.

  1. Select Subnet Scan, enter the Compressor’s IP Address into the Start IP box.  The End IP box should automatically fill.

Enter the Login and Password of the Compressor™ (Default:  admin / --- (blank)).

Disable the Auto / Default port option.  In the Discovery Port box, enter 8080, then click the Scan button.

**NOTE:  Use Port 8080, regardless of the Network Port value the Compressor™ has been assigned to.

  1. Once the Server has discovered the Compressor™ and its cameras, select each camera, then click Add Selected.  Allow the Server to re-add the Compressor™.

DW Spectrum® should now identify the Compressor™ correctly and allow users to monitor video streams from the analog cameras.

If you are unable to view the cameras after manually re-adding the Compressor™, close the DW Spectrum® Client, stop and restart the Server, then relaunch the DW Spectrum® Client.

Re-apply any Recording Licenses to the Compressor’s cameras as necessary.
