Tracker key features

Track multiple objects

Track more objects with the powerful core engine redeveloped from the ground up in Tracker 3.

Real-time system modelling with SimuLink

Vicon is the only optical motion capture provider able to offer low-latency, real-time modeling of robots out of the box. Streaming data by UDP, Tracker 3 talks directly to Mathworks’ SimuLink package for hardware-in-loop (HIL) testing. Tracker 3 will provide robot feedback directly into SimuLink for fast, low-latency end-to-end system testing.

Single camera tracking

Capture will continue even if the markers become visible to only one camera, resulting in fewer gaps and more dependable data.

Eye Tracking

Native implementation of Dikablis Eye Tracking system within Tracker 3 allows gaze data to be incorporated with third-party applications via VRPN as well as our Datastream SDK.

Flexible integration

Tracker’s robust integration methods enable you to read data in multiple formats, take advantage of the Datastream SDK and easily integrate with third-party applications.

New in Tracker 3

Capture larger volumes using fewer cameras.

Support for Vicon’s Viper X cameras brings active marker tracking to Tracker, allowing users to cover warehouse-scale volumes with fewer cameras.

Tobii Pro eye tracking

Tracker 3.8 added support for eye tracking with Tobii Pro Glasses to complement the native implementation of the Dikablis Eye Tracking system.

New Python Control API

Program your own commands with Python API support and stream data in OSC format with Open Sound Control integration.

How do I set up my network card?

1. Open the Network and Sharing Center and navigate to Change Adapter Settings. Vicon Vantage/Vero cameras are designated to one port.  For each Vue (or Bonita Video) camera connected, there will be additional network port used.

2. Right click on the proper port and go into the Properties. The Local Area Connection Properties window will open. Make sure only Internet Protocol Version 4 (TCP/IPv4) is selected.

3. Select Internet Protocol Version 4 (TCP/IPv4) from the list and select Properties to assign the proper IP address.

a .Vantage/Vero cameras will have the following IP Address: and Subnet Mask of:

b. The first VUE camera will have the following IP Address: and Subnet Mask of

c. Any additional VUE cameras the last IP value is incrementally increased by one. For example, the second VUE camera will be

Select OK to close out of the Internet Protocol Version 4 (TCP/IPv4) Properties.  And OK again to close out of the Local Area Connection Properties.  This will make sure all changes have been saved.

4. Feel free to rename the network port so it is easily identifiable. Such as ViconMX, VUE1 or VUE2

    What is Link Aggregation and how do I set this up in my Vicon System?

    Link aggregation is used to describe various methods for using multiple parallel network connections to increase throughput beyond the limit that one link (one connection) can achieve. Link aggregation is supported in Tracker 1.3+, Nexus 1.8.5+, Blade 2+.

    When setting up Link Aggregation ensure that you have the correct Network cards (Intel i340-T4 or the Intel i350-T4 cards) installed on your capture PC. Once you have the correct Network card(s) follow these steps:

    1. Make sure your three network ports have fixed IP addresses, and A maximum of nine NICs are allowed ( – inclusive).

    2. Connect the and ports to one Giganet/Power over Ethernet switch (POE) and to the other Giganet/POE. You will need an extra cable connecting your Giganets/POEs.

    3. Run Tracker/Nexus/Blade, set your workspace to Camera and select all the cameras in the System pane (you will need to expand Vicon Cameras). Please do note that there might be slight differences between the three applications.

    4. Turn the Giganet/POE connected to off then select all the cameras that just went red in the System pane.

    Select the Destination IP Address drop-down and select

    5. Select the remaining (green) cameras then scroll down their Properties, select the Destination IP Address drop-down and select

    6. Turn the Giganet/POE connected to back on. Select all the cameras in the System pane.

    Save your System configuration.

    How does Tracker work with VRPN?

    The Virtual-Reality Peripheral Network (VRPN) is a library that provides an interface between 3D immersive applications and tracking systems used for Virtools. Vicon Tracker 3 has a built-in VRPN server that will stream data natively into these applications or will allow for the development of simple interfaces using VRPN.

    How do I VRPN into Virtools from Tracker?

    Virtools, a commercial application, has support for VRPN and can be configured to connect with Vicon Tracker as follows.

    A full VRDevice.cfg file is included below.


    [email protected] is the way Virtools connects to the VRPN server within Tracker. The format is [email protected]_Name. This configuration file will look for an object called “Head” on the Tracker server called “TrackerPC.”

    vrpnTracker_0 [email protected]
    neutralPosition_0 0.0 0.0 0.0
    neutralQuaternion_0 0.0 0.0 0.0 1.0
    axisPermute_0 0 2 1
    axisSign_0 1 1 1
    trackerScale_0 1
    TrackerGroup_0 T0:0:6

    This VRDevice.cfg also contains other directives that:

    • Map the Vicon coordinates properly to the Virtools coordinates:
    axisPermute_0 0 2 1
    axisSign_0 1 1 1
    • Add a tracker group with:
    TrackerGroup_0 T0:0:6

    To complete the process, do the following:

    • Add the VRPN settings to a VRPack.cfg file, which is in the same folder as the .cmo. That way it can be tested with Virtools Dev.
    • For versions of Tracker before 1.2 in the composition, activate the Use Scale option and change the value of

    in your VRDevice.cfg file to 0.001 (converts Vicon mm to Virtools m).

    For a full description of any of these configuration options, please refer to the Virtools documentation.

    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.
