Mounting the camera
When mounting the camera on a fixer, pan/tilt, etc., use the cam-
era mounting screw hole located on the camera-mounting bracket.
CAUTION:
Use the screw with a length shorter than
7mm from a camera-mounting face.
Furthermore, make use of the rotation prevention hole to prevent
the camera from falling and securely mount the camera.
Special precautions must be taken for mounting the camera on a
wall or a ceiling. We are not liable for any damage caused by im-

Fall Prevention
• Exercise maximum caution when installing the unit to the wall
or ceiling. You should not engage in the installation work your-
self. Ask a professional to do the job, since the fall of the unit
can result in injuries and accidents.
• When installing the unit on a fixer, Pan/Tilt unit, etc., make sure
to install it firmly using a rotation-preventing hole provided to
prevent fall.
• To prevent fall, connect the unit to a section with sufficient
strength (ceiling slab or channel) using a fall prevention wire
such as a wire chain and the like. Use the black screw on the
back of the unit for installation.
Pay utmost attention to the length of the wire, too.
• Specified screw (M3 × 6 mm)
Never use any screw longer than the specified length as the
inside can be damaged.

Memo
● If the sensitivity adjustment LEVEL is turned excessively to
L, the sensitivity increases because of the AGC function of
the camera, and the image looks grainy.
● At Low light levels, video iris lens may “Hunt”. Please adjust
iris level on lens to minimise hunting.
Ⅵ For DC auto iris lens (auto iris lens without built-in
EE amp)
Set the VIDEO/DC switch on the side of the unit to “DC” and
adjust the LEVEL in the LENS ADJUST screen. (
