1
Make holes on the ceiling
● Use the provided template to make a hole
(R80 mm) for the connection cables to thread
behind the ceiling.
● If necessary, also open a screw hole to mount
the ceiling clamping bracket to the ceiling. In
this case, align the
AD FRONT markB of the
template in the direction where the camera
faces front and open the screw hole.
2
Pull the cables from the hole in the
ceiling
Pull out the fall prevention wire, power cable,
coaxial cable, control signal cable, alarm signal
cable and provided alarm cable that were mounted
to the ceiling slab from the ceiling.
Note:
● Mount the fall prevention wire on a firm place
with sufficient strength.
3
Remove the terminal cover
Loosen two screws on the ceiling clamping bracket
and remove the terminal cover.
4
Mount the fall prevention wire that
connects the ceiling clamping bracket
to the ceiling
Memo :
● The wire should be insulated from the ceiling
structure. If the ceiling structure is metal and
insulation is not provided between the
camera and the ceiling structure, image noise
may occur.
