• Network cable
Connect with an Ethernet cable (category 5 or better).
Important:
Maximum length of an Ethernet cable that can be
connected is 100 m.
• Output cable for adjustment-specific monitor
Connect with a coaxial cable (BNC) (only when check-
ing video signal output).
The monitor out connector is provided only for checking
the adjustment of the angular field of view on the video
monitor when installing the camera or when servicing.
• External I/O cables
Important:
• Input and output of EXT 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
setup instructions (PDF) for further information.
• When selecting "Alarm output" for EXT I/O termi-
nals, avoid signal collision with external signals.

• ALARM IN1/BW IN, ALARM IN2, ALARM IN3
Input specification: Non-voltage make contact
(DC 4 - 5 V internal pull-up)
OFF: Open or DC 4 - 5 V
ON: Make contact with GND (drive current: 1 mA
or more)
• ALARM OUT, AUX OUT
Output specification: Open collector output
(Maximum applied voltage: DC 20 V)
OPEN: DC 4 - 5 V by internal pull-up
CLOSE: Output voltage: DC 1 V or less (maximum
drive current: 50 mA)
• Microphone in connector
Connect the mini plug (ø3.5 mm) of a plug-in power
type microphone (sold separately).
Supply voltage: 2.5 V ±0.5 V
Input impedance: 3 kΩ ±10 %
Recommended sensitivity of microphone:
–48 dB ±3 dB (0 dB=1 V/Pa, 1 kHz)
Recommended cable length: Less than 1 m
Important:
Connect/disconnect the audio/video cables after
turning off the power of the camera and the amplifi-
er. Otherwise, loud noise may be heard from the
speaker.

• Audio output connector
Connect a monaural mini plug (ø3.5 mm). Use a pow-
ered external speaker.
Recommended cable length: Less than 10 m
Note:
Make sure that the stereo mini plug is connected to
this connector. When a monaural mini plug is con-
nected, audio may not be heard.
When connecting a monaural powered speaker,
use an optional conversion cable (mono-stereo).
