Arecont AV20576DN and DW Spectrum Compatibility Fix

-----------------------------------

Relevant DW Product:  DW Spectrum Server Software

Relevant Version:  v5.0.0.36183

Last Edit: May 9, 2023

-----------------------------------

 

Compatibility Issue

As of May 2023, the Arecont AV20576DN camera model was found to have compatibility issues when interfacing with the DW Spectrum Server software application. This compatibility issue can be characterized by:

1. DW Spectrum Server does not discover the AV20576DN camer
2. Signal/stream fails when trying to connect with the AV20576DN camera.

To resolve this issue until an official software update can be released for DW Spectrum IPVMS, our developers have provided a JSON resource that can be implemented to the DW Spectrum Server.

This article will outline where to copy the JSON file in the DW Spectrum Server folder to implement this fix.

 

**NOTE:  Making changes to the core files and configurations of the DW Spectrum Server files is not recommended unless necessary to resolve a specific issue. Please consult with your Digital Watchdog service representative or with DW Support for clarification if you are unsure if this fix applies to your needs or to an ongoing issue.

 

Downloading the File

Use the link below to obtain the JSON file. This file will be compressed into a folder upon download and compression software (Winzip, Winrar, etc.) is needed to unzip the folder.

Applying the JSON File to DW Spectrum Server

After downloading the JSON file from the link above follow the instructions below to implement this fix.

   1. Right-click on the camera in the Resource Tree and select “Delete” to remove the camera.
   2. If the camera is automatically re-discovered, you can disable the autodiscovery feature in the “System Administration > General > System Settings” menu. Be sure to reactivate this setting upon completing this guide as needed.
2. Stop the mediaserver application.
   1. For Windows – Right-click on the ‘DW’ icon that appears in the Windows system try and select “Stop Server (started)”.

         • DW Blackjack units sold with Ubuntu 18.04 – Dw5pectrum
      3. Once root administrator rights have been gained, use the command:

 

3. Copy and paste the downloaded files into the following folder locations.
   2. ‘resource_data.json’ file location:

      • For Ubuntu Linux – /opt/digitalwatchdog/mediaserver/bin/

 

4. Start the mediaserver application again.
