Basler video cameras and Nexus 2.6

If Basler digital cameras will be connected to Nexus 2.6, ensure you have updated to the Basler Pylon5 SDK and drivers (v5.0.0), which are available from the Vicon website.

If you are using an Intel i340, i350 or i210 network card, when you install the drivers, select the option for Filter drivers, not Performance drivers.


The Pylon5 driver supports:

  • Basler GigE cameras under both Windows 10 and Windows 7.
  • Basler FireWire cameras (A600 series) under Windows 7 only.
MATLAB and Nexus 2.6

If you are planning to use MATLAB with Nexus 2.6, ensure that, in addition to installing MATLAB, you install the .Net Framework version 4.5.

Systems supported for Nexus 2

Before you install Vicon Nexus 2.6, note the following limitations on supported systems:

  • Nexus captures data only from Vicon systems (including Vicon Vero and Vicon Vue, Vicon Vantage, Vicon Bonita, Vicon T?Series, and MX+ and MX cameras and units).
  • Nexus 2.6 does not support connection to the Reference Video System (Nexus Slave application).

Upgrading Nexus

This section describes functionality that is dependent upon the version of Vicon Nexus that is being upgraded:

Upgrading from Vicon Nexus 1.x


This section applies only to versions of Nexus that are earlier than 2.0.

Nexus 2.6 installs into its own folder, called Nexus2.6. If you already have Nexus 1.x installed, it will remain installed alongside the new Nexus installation.

On installation, Nexus 2.6 automatically scans for Nexus 1.x files, displays a list of any older files that it finds, and provides an automated system for importing these into Nexus 2.6.

This process copies all the old files and converts the copies, ensuring that original files are not moved, altered, or destroyed.


Custom pipelines are not copied from earlier versions of Nexus, so if you want to use your old pipelines, copy them from the following Vicon product installation folder (by default in C:\Program Files (x86)\Vicon or C:\Program Files\Vicon):


and paste them to the following location in the Vicon production installation folder (by default in C:\Program Files (x86)\Vicon or C:\Program Files\Vicon):


They will then be available in the Legacy pipeline operations in Nexus 2.6.

For more information on the installation and licensing process, see Installing and licensing Vicon Nexus .

Upgrading from earlier versions of Nexus 2

If you are upgrading from a previous version of Nexus 2, during installation a dialog box gives you the option of adding the Auto Intelligent Gap Fill button and/or the Add to Quick Report button to your Nexus toolbar. For more information on these features, see Automated gap-filling  and Quick Reports. To add the additional button(s) to your toolbar, click Upgrade Files.

On first launch, Nexus 2.6 scans the installation directories of earlier versions of Nexus 2 and offers to automatically transfer custom objects that it finds.

If you click Import Files, Nexus 2.6 copies custom calibration objects from earlier versions of Nexus (2.0 and later) to the Public Documents folder (eg C:\Users\Public\Documents\Vicon\Nexus2.x\CalibrationObjects).


When you create new custom calibration objects, ensure you save them into this folder (not to the Nexus installation folder), so that they are available to future versions of Nexus.
