You may need to:
♦
Clean the lens.
A clean lens ensures that the images acquired by the
Camera Heads are accurate. This is important to the
performance. The lens can be cleaned with a
commercial glass cleaner and a lint-free cloth.
You may need to clean the lens daily in dusty
environments.
♦
Move the Stereo Tracking Head.
The possibility that the wrong head was installed for
that portal always exists. Verify the correct head is
being used, if correct; verify the height and placement
are accurate.
