4 ART Tracking Cameras
The RJ45 connection between TRACKPACK/C camera and controller is
used for power supply and synchronization signal. It is not a standard
Ethernet connection! That is why connecting the RJ45 connector to
any other than the equivalent port of the controller may damage the
camera or the connected partner.
Mounting The TRACKPACK/C cameras are optimized for a predefined range of mea-
surement volumes. System operation in smaller or bigger measurement volumes can
lead to reduced accuracy. The measurement volume can be adjusted within certain limits
simply by changing the flash intensity of the ART infrared cameras (see chapter 8.5.1 on
page 146).
i
The flash intensities should not be too high. In general, a flash inten-
sity of 3-4 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 carrier for the TRACKPACK/C can be attached to the camera as shown in figure
4.11.
