Note
• Special attention is required when installing the camera to the wall
or ceiling. You should not carry out installation work yourself. Ask a
professional to do the job, because injuries and accidents may occur if
the camera falls.
• To prevent this camera from falling, connect it to a strong section (a
ceiling slab or channel) using a fall prevention wire.
• When you attach the camera body to the ceiling, be sure to wear safety
goggles to protect your eyes from falling objects.
Mounting the lens

• Use a Megapixel lens only.
1 Check the lens mount before mounting the lens.
• The VN-H37U has the CS mount.
• The lens mount size (a) must be as shown in the table below.

• Never use a lens whose dimension
(a) is more than the specified value.
Otherwise, the lens may not be
mounted correctly, or internal parts
of the camera may be damaged.
Also, the camera may fail.
2 Mount the lens securely by rotating it clockwise (CW).
3 When using a DC iris lens, connect the lens cable
to the IRIS terminal at the side of this camera.
Memo

When connecting the AC 24 V power cable (VN-H57U)
• When power is supplied, the [STATUS] indicator lights up on the
camera side panel.
Note
• Always use an AC 24 V power supply that is insulated from the primary

may fail or damage the camera.
• If you use both the AC 24 V power cable and the PoE-based LAN cable
simultaneously, the camera may fail. Always supply power using either method.
Mounting this camera onto a fixer,
pan/tilt unit and similar object
When you mount the camera onto a fixer, pan/tilt unit or
similar object, use the tripod screw hole (1/4-20UNC) of the
camera-mounting bracket.
When you mount the camera on a high place, fix the
fall-prevention wire to the wire attachment screw on the
camera rear panel.

• Take note of the length, strength and pull of the fall prevention wire. For
1/4-20UNC
the fall prevention wire use the insulation material. Make the wire length
as short as possible.
The wire must be sufficiently strong to hold the weight of the camera and
the total weight of the lens and fixer. (Also, make sure that the wire ends
are terminated carefully)
• Use the screws mounted on the camera rear panel to hold the fall
prevention wire.
• Mount the fall prevention wire using an attachment screw for the fall
prevention wire.
Use the screws (M3 x 6 mm) mounted on the rear panel of the camera to
hold the fall prevention wire. Do not use a screw that is longer than 6 mm
as doing so may damage the inside of the camera.

Connecting the monitor signal output
terminal to the coaxial cable
Connect a test monitor to the [MONITOR] terminal.
Use this terminal to adjust the field angle during camera setup and to
adjust the focus in Focus Assist mode. Connect an RCA video cable
from this MONITOR terminal to the video monitor. When using a PAL
system monitor, set the [MONITOR] switch to the "PAL" position. Then,
press the RESET button to restart the camera.
