7.2.1 AutoTrack Settings and Recommendations
AutoTrack operates by recognizing an individual in motion and zooms-in to approximately 50%
of the field of view for an average target height of six feet. In addition to the camera height,
other factors may interfere with AutoTrack operation.
Setting the Camera Height
To ensure smooth tracking set the Camera Height accurately. Bosch recommends a minimum
camera height of 3.6 m (12 ft).
1. Press OFF-90-ENTER to turn off the command lock.
2. Press ON-46-ENTER to access the Main Menu.
3. Use the joystick to highlight the Advanced menu.
4. Press Focus/Iris to open the menu.
5. Highlight the Camera Height option and press the Focus/Iris button.
6. Enter a value between 3.6 m (12 ft) and 100 m (328.1 ft).
7. Press Focus/Iris again to accept the camera height value.
8. Exit the Advanced menu; then exit the Main menu.
Ensuring Smooth AutoTrack Operation
Factors such as the viewing angle and unwanted motion (from trees, for example) may
interfere with AutoTrack operation. Use the following recommendations to ensure smooth
AutoTrack operation:
Mount/Mounting Surface Stability
Mount the camera in the most stable position. Avoid locations affected by vibrations,
such as those caused by a roof-top air conditioner. These vibrations may cause
complications when the camera zooms-in on a target.
Use the pendant arm mount, if possible. This mount option provides the most
stability for the camera.
Use guy wires to protect against strong winds if using the parapet mount.
Field of View
Select a location and viewing angle that allows the flow of people to move across
the camera’s field of view.
Avoid motion that moves directly towards the camera.
Avoid locations that attract large numbers of people, such as retail stores or
intersections.
Unwanted Motion
Use the Virtual Masking feature (see Section 7.3 Virtual Masking (500i Series Only),
page 52) to mask unwanted motion from trees or cars.
Bosch recommends that you draw the virtual mask 10% larger than the object to be
masked.
Avoid neon lights, flashing lights, night time lights, and reflected light (from a
window or mirror, for example). The flickering of these lights can affect the
AutoTrack operation. Use a Virtual Mask to hide these type of lights if they cannot be
avoided.
Check the virtual mask periodically to ensure that it still covers the entire object to
be masked. Adjust the mask if necessary.
