How to Apply DW Spectrum v4.1 SO Plugin for MEGApix® IVA/IVA+™ Cameras (Ubuntu/Linux)

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

Affected Roles:  Administrator, Owner

Related Digital Watchdog VMS Apps:  DW Spectrum® IPVMS (Ubuntu/Linux)

Complexity:  Medium

Software Version:  DW Spectrum® IPVMS v4.1.0.31401 or newer

Last Edit:  March 1, 2021

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

Upgrade to IVA+™

Digital Watchdog’s MEGApix® IVA+™ (Intelligent Video Analytics) IP Camera Series comes preloaded with robust video analytic tools, ready for use upon installation.  However, in order to utilize these intelligent features, a plugin must be added to DW Spectrum® Servers first.

This article will outline how to add the analytic plugin to the Ubuntu/Linux version of the DW Spectrum® IPVMS platform.

**NOTE:  For merged DW Spectrum Systems, you will want to add the .so plugin to each Server in the merged array.

**NOTE:  This article is for Ubuntu/Linux operating systems only.  If you are using a Windows OS, please use Applying DW Spectrum v4.1 DLL Plugin for MEGApix IVA/IVA+ Cameras (Windows).

Supported/Affected Devices:

  • DW Blackjack Servers (Ubuntu/Linux)
  • MEGApix® IVA/IVA+™ Camera Series

Analytic Options

The MEGApix® IVA™ and MEGApix® IVA+™ models feature analytic features that can be used to detect when people cross into a designated area, keep count of how many times a drawn line is crossed, and more.

It is worth knowing the difference between the IVA™ and IVA+™ options.  Cameras can be purchased pre-loaded with options of either IVA™ or IVA+™. 

The difference between the two options has to do with the types of analytic events that can be used.

See the table below for the difference between IVA™ and IVA+™.

Applying DW Spectrum® 4.1 SO Plugin

To add the DW Spectrum 4.1 SO plugin file to DW Spectrum IPVMS (Ubuntu/Linux):

  1. Download the Spectrum 4.1 SO plugin file to the desktop of your computer from the DW Spectrum® IPVMS product page.
    • The file can be found under the Software tab, then under Plug-in

  1. Once the plugin file has been copied to the desktop, open the Command Terminal (CTRL+ALT+T).
  1. In the Terminal, switch to the super user by using the following command:

sudo su

Press ENTER, then enter the root password of:

admin

**NOTE:  The root password will not display as you type.

  1. Next, stop the DW Spectrum® mediaserver process by using the following command:

service digitalwatchdog-mediaserver stop

  1. After stopping the mediaserver, navigate to the desktop by using the command:

cd Desktop

  1. The file libdw_edge_analytics_plugin.so should be saved to the computer’s desktop at this time.  If so, copy the file to the plugins folder of the mediaserver by using the following command:

cp *.so /opt/digitalwatchdog/mediaserver/bin/plugins

The libdw_edge_analytics_plugin.so will now be found within the plugins folder for the Digital Watchdog mediaserver.

  1. Next, start the mediaserver process by using the following command:

service digitalwatchdog-mediaserver start

If you open the Camera Settings menu of an added IVA/IVA+™ camera, in an instance of the DW Spectrum® Client, you can select the Plugins tab to check the current Version of the plugin.

This completes the upgrade process for IVA™ support for DW Spectrum® IPVMS.
