I just installed the latest version of software but the cameras no longer connect when I run it. What can I do?

If the cameras continue to connect with the previous version of software but don’t in the latest version then the software is probably being blocked by the Windows Defender Firewall. Although Vicon officially specifies that the Firewall should be turned off completely to ensure unobstructed communication with the cameras and connectivity devices, sometimes institutional protocols mandate it to be turned on. If this is the case:

  1. Go to Control Panel > Windows Defender Firewall and click on Allow an app or feature through Windows Defender Firewall.
  2. Scroll down the list of applications to look for the instance of Vicon software (Vicon Nexus, Vicon Tracker, Vicon Shogun, Vicon Evoke).
  3. Select the application and click Details to ensure it refers to the version you are trying to run.
  4. Click on Change Settings to enable the networks (Domain, Private, Public) that match those of the previous version. If this option is disabled then please contact the system’s administrator or your institution’s IT personnel for assistance.
  5. Click OK.
  6. Restart the Vicon software.

If this does not resolve the issue then please contact Vicon Support.

I am working on a computer that is different to our normal processing computer. How can I bring over all of my settings from the processing computer?

Most settings for Nexus 2.x can be found in C:\Users\Public\Documents\Vicon\Nexus2.x\Configurations.  This includes, but is not limited to, pipelines, view options and monitors.  A few exceptions include:

  1. Model Templates; These can be found here: C:\Users\Public\Documents\Vicon\Nexus2.x\ModelTemplates
  2. ProCalc Schemes; These can be found here: C:\Users\Public\Documents\Vicon\Eclipse
  3. Toolbar icons: C:\Users\<user name>\AppData\Roaming\Vicon\Nexus2.x\Configurations\Toolbars

Simply copy the files you require from the relevant folder on the processing computer and paste them in their corresponding folder on the new computer.

If you cannot find a setting or are having issues with this process, please contact Vicon Support.
