Tracking Cameras
simply by changing the flash intensity of the
ART
infrared cameras (see chapter 8.5.1 on
page 146).

The flash intensities should not be too high. In general, a flash inten-
sity of 50-60 might be sufficient.
Major changes of the measurement volume may require different lenses and thus a new
determination of camera parameters. These changes have to be done at the
ART labs.
Be aware that a tracking system is very sensitive to camera movements. Therefore the
cameras have to be mounted in a way that camera movements (especially vibrations) are
reduced as much as possible.

Mounting on tripods may be sufficient for presentations and prelimi-
nary installations, but is not recommended as a permanent solution!
The TRACKPACK/E camera is equipped with UNC 1/4" threads on both sides and can
thus directly be mounted to tripod heads.
The carrier for the
TRACKPACK/E can be attached on both bottom and top side of the
camera. Attach the carrier to the camera in a similar way to figure 4.2 on page 30. For
more flexibility, the T-piece can be mounted pointing forward or backward. Note, the ceil-
ing suspension is already connected to the carrier in figure 4.2.
Only use screws supplied with the ceiling mount for mounting it.
Also, use all the parts supplied with the ceiling mount - especially the
toothed washer is quite important.
Never unfasten other screws on the cameras (see chapter 1.2 on page
14). Otherwise, the camera might be damaged and liability and war-
ranty is void.
Feel free to contact ART in case you want to realise a more complex installation. We will
assist you in your planning.
Make sure to install the system in a way that you can easily access the cameras and
its cables. Be especially careful to mount the cameras firmly so they cannot fall down.
Unsecured cameras may pose a serious hazard to health and safety.
Shock and vibration can permanently destroy the internal calibration
of the cameras. De-calibrated cameras have to be recalibrated in the
ART labs.
Figure 4.3 on page 31 shows the correct mounting for a camera to a wall with a carrier
using the example of an
ARTTRACK2 camera. Make sure to not fall below minimal
distance to the wall so enough room is left for the cables and to allow readjustment of
the camera angles and maintenance. For easy adjustment, it is highly recommended to
mount the ceiling mount in a way that the threaded bolt is vertical. This way heading and
elevation of the camera view can be adjusted individually.
Use strong dowels and screws for mounting the cameras to walls or ceilings (see figure
4.3 on page 31).
