== Installation (as performed in August 2020) ==

=== Mount cameras on joints and joints on clamps ===

Make sure that the camera is not upside-down.

=== Prepare 16 safety ropes ===

# Cut to the right length
# Use a lighter at both ends
# prepare 8-knots as in rock climbing

=== Mount cameras on truss and wire them with the two switches ===

Mount the 16 cameras in the corners and at each 1/4 of the edges.
Use the safety ropes, and wire them to the two switches as below.

=== Orient cameras and adjust focus ===

Once the setup is up-and-running,
adjust the focus of each camera using a marker
at 2/3 of the working distance.
Skype and screen sharing may be helpful.
