In case the system needs to be reassembled
Mount cameras on joints and joints on clamps
Make sure that the camera is not upside-down.
Prepare 16 safety ropes to prevent accidental camera drops

- Use a lighter at both ends

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. Use a remote desktop app and ethernet connection.
- In the corners: the bottom of FoV is parallel to the long edges, and the bottom right corner is vertical.
- At 1/4 of a short: the top of the FOV is horizontal, and the camera points toward the center.
- At 1/2 of a short edge: the bottom of the FOV is vertical, and the camera aims downward.
- At 1/4 of a long edge: the top of the FOV is horizontal, and the camera points toward the center.
