Mount Adapter
The camera mounting screw hole is for mounting the camera
onto a mounting bracket. The camera is originally designed to
be mounted from the bottom, however, a top-mounting type is
also available. To mount from the top, remove the mount
adapter from the bottom of the camera by removing two fixing
screws. Attach the mount adapter to the top as shown in the
diagram, then mount the camera on the mounting bracket.
Make sure that two original screws are used when mounting
the mount adapter; longer type screws may damage inner
components, too shorter type screws may cause the camera
drop.
