Fall Prevention
Exercise maximum caution when installing the unit to the wall or
ceiling. You should not engage in the installation work yourself. 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.
For the used safety cable, pay particular caution to the length,
strength, pull, material (insulation), etc.
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.
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
