# Tracker 3.6.1 new features
> Macro (anchor)
The following enhancements were added to Vicon Tracker 3.6.1:
- [Entrance Threshold can now be per object type](#EntranceThresholdcannowbeperobjecttype)
- [System synchronization from 100 Hz square wave](#Systemsynchronizationfrom100Hzsquarewave)
## Entrance Threshold can now be per object type
> Macro (anchor)
Location: **Resources** pane > **Objects** tab > **Object Type Preset** section > **Manage Presets** > **Objects Presets** dialog box
You can now define an **Entrance Threshold** (the minimum proportion of markers that must be visible to the cameras before the object is booted) per object type in the **Object Presets** dialog box, instead of having to apply it globally for all objects.
**To apply an Entrance Threshold to an object:**
1. On the **Objects** tab, in the **Object Type Preset** section, click **Manage Presets**.
2. In the **Object Presets** dialog box, create a new preset and in the **Object Tracking** section, specify the require **Entrance Threshold**.
3. On the **Objects** tab, select the object to which you want to apply the preset.
4. In the **Object Type Preset** section, select the preset that you created.
## System synchronization from 100 Hz square wave
> Macro (anchor)
The VESA sync input on Vicon Lock devices now supports the connection of a 100 Hz square wave signal for synchronizing the Vicon system to an external clock.
The signal must be 5V peak, with a 50% duty cycle.
The following diagram shows the front view of a VESA sync input, which is a 3-pin mini-DIN socket.
# Tracker 3.6 new features
The following new features were added to Vicon Tracker 3.6:
- [Improvements to tracking](#Improvementstotracking)
- [Easier checking for firmware updates](#Easiercheckingforfirmwareupdates)
- [Motion Model filter for selected objects](#MotionModelfilterforselectedobjects)
- [32-bit version of Tracker](#32-bitversionofTracker)
- [Disable/enable camera strobes](#Disable/enablecamerastrobes)
## Improvements to tracking
> Macro (anchor)
Several improvements to tracking include:
- The ability to resolve objects that are close together now enables very small objects to be tracked when they are closer than 10 mm.
- Greater intelligence in the centroid-fitting of data minimizes the impact of large reflections on latency of the system.
- More robust centroid-fitting with objects that are closely similar.
## Easier checking for firmware updates

Location: **Help** > **Check for firmware updates**
Tracker provides a quick and easy way to check when new firmware is available for your cameras.
**To check the latest release firmware version:**

The **Checking Firmware Version** dialog box displays information about the latest released firmware version.
**To check the firmware that your system is using:**
- Ensure the system is in **Live** mode, and in the **System Resources** pane, right-click **Local Vicon System** and then click **Reprogram Vicon Firmware**.
The firmware version currently used by your system is displayed in the **Version** column for every connected device.
To download the latest firmware, visit [www.vicon.com/downloads/utilities-and-sdk/camera-firmware](http://www.vicon.com/downloads/utilities-and-sdk/camera-firmware).
You can then update your firmware using the **Reprogram Firmware** dialog box.

## Motion Model filter for selected objects
> Macro (anchor)
Location: **Resources** pane > **Objects** tab > **Object Type Preset** section > **Manage Presets** > **Objects Presets** dialog box
You can now apply the **Motion Model** filter, which enables Tracker to detect static objects, to individual objects.
**To enable Tracker to detect an object as stationary:**
1. On the **Objects** tab, in the **Object Type Preset** section, click **Manage Presets**.
2. In the **Object Presets** dialog box, create a new preset and select **Motion Model**.
3. On the **Objects** tab, select the object that you want Tracker to detect as stationary.
4. In the **Object Type Preset** section, select the preset that you created.
## 32-bit version of Tracker
> Macro (anchor)
A version of Tracker 3.6 that runs under 32-bit Microsoft® Windows® is now available.
To obtain the 32-bit version, please contact [Vicon Support](https://vicon-help.atlassian.net/wiki/spaces/Tracker310/pages/13927346).
> ℹ️ **Note**
> ℹ️ Vicon recommends the use of the 64-bit version of Tracker, but the 32-bit version is provided to enable Tracker to be used on older PCs. However, the 32-bit version is provided as-is and with no guarantee of support.
## Disable/enable camera strobes
> Macro (anchor)
Location: **System Resources** pane > **Vicon Cameras** node > Vantage or Vero camera(s) selected > **Properties** pane > **Settings** section
A new **Enable Strobe** setting enables you to disable or enable strobes on Vantage or Vero cameras without affecting the shutter period.
