How to manually install Symphony Web Client ActiveX components


In cases where live video and historical video playback is not working via the Symphony Web Client, ensure the following:

  • You are using a supported versions of Internet Explorer. Refer to the Symphony Installation Guide for details on browser compatibility.
  • The browser is running in compatibility mode and Symphony server's IP is listed as a Trusted Site. Refer to the browser documentation for details.

If live video and historical video playback problems persist, the issue may be because of missing or non-functional ActiveX components. Installing the Symphony client on that machine will resolve the issue.

However, if installing the Symphony client isn't preferable (which resolves the ActiveX components not working in the web client), you can attempt to install the necessary ActiveX components manually on the machine.

Manually Install ActiveX Components via a Batch File

1. On a machine running the Symphony server or client (but not the machine where you want to run the web client) go to the following directory:

c:\Program Files (x86)\Senstar\Symphony\WebRoot

2. Locate the file in this directory. Copy this file to a USB key, thumb drive, or other portable data device. You need a copy of this file on the machine where you want to access the web client for the Symphony server using Internet Explorer.

On that separate Web Client machine:

3. Create a new temp directory (C:\Temp) and copy the VideoRecvCtrl.Cab file to this directory.

4. Create a batch file that contains the following code:

cd C:\Temp\

expand -f:*.* c:\temp\

5. Save the batch file on the local web client machine in the temporary directory you created (C:\Temp).

6. Run the batch file and let it complete.

7. Ensure that Internet Explorer is configured to prompt for unsigned ActiveX controls.

8. Access the web client for the Symphony server using Internet Explorer to confirm whether the ActiveX components and live video and historical video playback is now working.
