Installation Guide

Specification of cable (wire): AWG #22 - #28,
Single core, twisted
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. Refer to
the Operating Instructions (included in the CD-ROM)
for further information about the EXT I/O terminal 2
and 3 (ALARM IN2, 3) settings ("Off", "Alarm input",
"Alarm output" or "AUX output").
 • ThedefaultofEXTI/Oterminalsis"Off".When"Off"is
selected, it is possible to connect external devices as
well as the input setting.
 • WhenusingtheEXTI/Oterminalsastheoutputtermi-
nals, ensure they do not cause signal collision with
external signals.

ALARM IN1/ DAY/NIGHT IN, ALARM IN2, ALARM IN3
Input specification: No-voltage make contact input
(4 V - 5 V DC, internally pulled up)
OFF: Open or 4 V - 5 V DC
ON: Make contact with GND (required drive current:
1 mA or more)
 • ALARMOUT,AUXOUT
Output specification: Open collector output (maxi-
mum applied voltage: 20 V DC)
Open: 4 V - 5 V DC by internal pull-up
Close: Output voltage 1 V DC or less (maximum drive
current: 50 mA)
• Microphone/line input connector
Connect a monaural mini plug (ø3.5 mm).
 • Inputimpedance:Approx.2kΩ
 • Recommended cable length:1m {3.28feet} or less
(for microphone input)
10 m {32.8 feet} or less (for line input)
 • Recommended microphone: Plug-in power type
(option)
 • Supplyvoltage:2.5V±0.5V
 • Recommendedsensitivityofmicrophone:–48dB±3
dB (0 dB=1 V/Pa,1 kHz)
 • Recommendedplug:Ltype
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 powered speaker.
 • Recommendedcablelength:10m{32.8feet} or less
 • Recommendedplug:Ltype(Astraighttypeplugmust
be 40 mm {1-9/16 inches} 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 (Because of the
pin array difference, it is difficult to fit an L type plug
into this connector.)
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 onto the center of the camera
mount bracket.
