Important:
• Do not connect 2 wires or more directly to a terminal.
When it is necessary to connect 2 or more wires, use
a splitter.
• Input and output of the external I/O terminal 2 and 3
can be switched by configuring the setting. The
default of EXT I/O terminal 2 is "ALARM IN 2" and of
EXT I/O terminal 3 is "ALARM IN 3". It is possible to
determine whether or not to receive input from EXT
I/O terminal 2 and 3 (ALARM IN2, 3) by selecting
"Off", "Alarm input", "Alarm output" or "AUX output"
for "Terminal alarm 2" or "Terminal alarm 3" on the
[Alarm] tab on the "Alarm setup" page. Refer to the
Operating Instructions (PDF) for further information.
• When using the EXT I/O terminals as the output termi-
nals, ensure they do not cause signal collision with
external signals.

Important:
• Connect/disconnect the audio cables and turn on the
power of the camera after turning off the power of the
audio output devices. Otherwise, loud noise may be
heard from the speaker.
• Audio output connector
Connect a stereo mini plug (ø3.5 mm) (Audio output is
monaural.). Use an external speaker with amplifier.
• Recommended cable length: 10 m {32.8'} or less
• Recommended plug: L type (A straight type plug must
be 40 mm or less.)
• Monitor out connector for adjustment
Connect a monaural mini plug (ø3.5 mm) (only for check-
ing if images are displayed on the monitor).
• Recommended plug: Straight type
Important:
• The monitor out connector for adjustment is provided
only for checking the adjustment of the angular field
of view on the video monitor when installing the cam-
era or when servicing.
It is not provided for recording/monitoring use.
• Black bands may appear at the top and bottom or
right and left of the screen. (That does not affect the
adjustment because the angular field of view is not
changed.)
Step 6
Mount the camera onto the camera mount bracket
(accessory). Fit the lock plate of the camera onto the
guide part of the camera mount bracket, and rotate the
camera clockwise after inserting the camera while putting
the center of the camera (screw hole for a tripod) onto the
center of the camera mount bracket.
