About the application
AXIS Radar Autotracking for PTZ is an application that uses data from Axis radars to direct one or more PTZ cameras towards moving objects. You can install the PTZ cameras close to the radar, or distribute them throughout the site you’re monitoring. The radar measures the absolute distance and speed of moving objects, and the application calculates the best pan, tilt, and zoom settings for the PTZ cameras based on their location and current view.
The tracker groups together multiple objects to fit within the camera’s view, and its default behavior is to follow these priorities:
It tracks the same object.
It minimizes camera movement.
It tracks each object with at least one PTZ camera, if available. If not, it tracks the closest object.
Considerations
For a list of supported PTZ cameras, see axis.com/products/axis-radar-autotracking-for-ptz#compatible-products
The application is suitable for outdoor sites with a limited amount of activity, or indoor sites with ceiling heights of 7 m (23 ft) or more. Crowded sites, like train stations, are not recommended.
You need to place the PTZ camera within the radar’s detection range. For more information about detection range, see the user manual for your radar on help.axis.com.
The application is not designed to run at the same time as the built-in autotracking service in Axis radars. If you switch from one service to the other, reset the radar to factory default settings.
The radar can miss some objects that are visible to the camera, for example if they are outside the radar’s detection range.
The radar can change the classification of a physical object during its path through the scene. Depending on your configuration, this could cause a changed tracking behavior.
High latency can affect the tracking performance. To minimize latency, run the application on a computer that is connected to the same network as your radar and PTZ camera.
An operator can always take control of the PTZ camera and override AXIS Radar Autotracking for PTZ. For more information, see Override tracking.
If you change any settings in the radar, restart the service.
The application might disable Proportional speed in the PTZ camera. This setting is not restored when you remove the camera from the application.

- Note
We recommend that you turn off tracking for the PTZ camera until you have paired it with all intended radars. Right-click on the PTZ camera and click Turn off. If you pair the camera with more than two radars, turn off the PTZ tracking for each group.
Create a new group for each radar, and add the same camera to each group.
When you pair one PTZ camera with multiple radars, the PTZ camera treats the radars the same and will track any detected objects based on the control queue settings in the camera.
Calibrate the PTZ camera
When you add a PTZ camera in the application, you have to calibrate it. To make the calibration easier, there are a few things to consider:
The calibration is based on three positions: the location of the PTZ camera and two calibration points. These three positions create a plane.
The calibration points are used for calibrating the camera view to the background image. This means that you can select calibration points outside the radar’s detection zone.
Select the first calibration point in the same direction as the most distant point of the detection zone. Preferably, select a calibration point that is further away. If the calibration point is close to the radar, a small angular error will result in large deviations at more distant object locations. The detected object might fall outside of the camera view.
Select a second calibration point at, or beyond, the perimeter of the area of interest. The performance of the camera tracking works best inside the triangle made up of the PTZ camera position and the two calibration points.
Consider the elevation in the scene when you select the calibration points. If the three positions are set on different height levels, the application assumes that the whole detection zone is a tilted plane. The radar has no information about height. If an object is detected on another level than the area set out from the calibration points, the PTZ camera might be tracking below the object of interest.
Use the tracker only outside office hours
Go to the radar’s web interface and set up a schedule that defines the hours you want the tracker to work. You can also use the default schedule After hours.
In the Windows® task bar, right-click AXIS Radar Autotracking for PTZ and select Open AXIS Radar Autotracking for PTZ.
Right-click the group and select Group settings.
Turn on Tracking schedule.
Select the schedule you created in the radar.
If you can’t find the schedule in the list, click to refresh the list.
If you want to use the tracker after office hours on weekdays and during weekends, you need to invert the default schedule Office hours.
Follow the instructions in the list, select the default schedule Office hours, and then select Turn OFF tracking according to schedule.
Track a specific object type
You can select if you want the tracker to only track vehicles, humans, or unknown objects.
In the Windows® task bar, right-click AXIS Radar Autotracking for PTZ and select Open AXIS Radar Autotracking for PTZ.
Expand the group that the camera belongs to.
Right-click the PTZ camera and select Camera settings.

Use scenario-specific filters in the radar
You can set up the tracker to only track objects during radar alarms. Radar alarms are based on scenarios, which are a combination of triggering conditions and detections settings that you configure in the radar’s web interface.
Before you start:
Create a scenario in the radar where you define the object type to trigger on, and if the radar should trigger on objects moving in a defined area, or objects crossing two virtual lines.
For detailed instructions, see the radar’s user manual at help.axis.com.

Troubleshoot the calibration
If the camera isn't tracking objects correctly after calibration, it’s likely due to one of the following causes:
The scale is not set correctly during map calibration.
Selected points on the map don't match the calibration points.
Try the following:
Make sure to use as much as possible of the radar stream. Position the radar so its field of detection covers as much of the stream as possible.
Make sure that the scale of the map is correct.
- To adjust the position of the radar and the scale of the map, go to Radar > Map calibration in the radar’s web interface. For detailed instructions, see the user manual for your radar on help.axis.com.
To validate the calibration:
In the radar’s web interface, go to Radar > Settings > Object visualization and set Trail lifetime to 1 minute.
On the site you’re monitoring, ask someone to walk from the radar to the first calibration point and stop there.
In the radar’s web interface, check that the trail on the map corresponds with reality. If the trail on the map deviates, redo the map calibration.
When you’re happy with the map calibration, re-calibrate the PTZ camera.
