When mounting the camera on a fixer, pan/tilt, etc., use the camera mounting screw hole located on the camera-mounting bracket.

CAUTION:

Use the screw with a length shorter than 7mm from a camera-mounting face.

MAX. 7mm

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 improper installation.

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.

Set the VIDEO/DC switch on the side of the unit to “DC” and adjust the LEVEL in the LENS ADJUST screen. ( Page 35)
