4 ART Tracking Cameras
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 ARTTRACK5 camera is equipped with UNC 1/4" threads on both sides and can thus
directly be mounted to tripod heads.
The carrier for the ARTTRACK5 can be attached on both bottom and top side of the
camera. Attach the carrier to the camera as shown in figure 4.2 on page 30. For more
flexibility, the T-piece can be mounted pointing forward or backward. Note, the ceiling
suspension is already connected to the carrier in figure 4.2.
