You may mount the camera in any way you wish as long as it is electrically isolated from the rest of the chassis (the camera enclosure is grounded) and satisfies all other rules (it must be inside your robot volume, etc.).
The KOP included a pan/tilt mount for the camera that is one option for mounting it. The parts of this mount are identified on pages 16 and 17 of the
KOP Checklist (excluding the last 2 items on page 17).
The assembly of this mount is not specified anywhere in a step-by-step manner, but can be determined by looking at the picture of the full assembly on the second page of this document:
