2-8 Installation for Embedded dome Camera
Locations with suspended top suit the dome camera with in-ceiling installation style,
which appears to be a hemisphere, having elegant-look and good concealment. The
in-ceiling style installation applies to solid locations of the ceiling. First, select the
desired location, pencil the outline of the upper housing on the ceiling and make a
corresponding-size bore(about 210mm diameters for Seven-inch Dome Camera, about
240mm diameters for Nine-inch one), then insert the upper housing into the ceiling, and
press the spring pinning boards against the edge of the ceiling opening. After that,
tighten the screw adjusting the spring pinning boards, and lock the upper housing in the
ceiling tightly. For the sake of better safety, please use a metal wire rope to connect the
top of the upper housing to a reinforced structure of the ceiling. (The wire rope is
required to bear at least 5 times the weight of the dome camera.)
