Note
• For safety reasons, turn on the power only after
confirming that all the connections are completed.
• Be sure to turn off the camera before connecting
cables.
• 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.
• To use an AC 24 V power supply, remove the
factory-installed tape from the power cable, connect
to an AC 24 V power supply, and wrap the connector
with new insulation tape and waterproof tape.
Audio cable connection
Connect the audio cable for an audio device.
Audio cable (Brown and White) (MIC IN) : Connect to a condenser microphone that has a plug-in power
Audio cable (Black and White) (LINE OUT) : Connect to a speaker with a built-in amp, etc.
Memo
• A shielded audio cable is recommended.
* For the location to connect the audio cable, refer to [Cabling] (
Alarm I/O cable connection
Alarm input
Connect an infrared sensor, door sensor, metal
sensor, a manual switch or other device.
• To avoid noise entering the internal circuit, enter the
non-voltage contact signal in the Alarm IN terminal.
• Do not supply voltage.
• The alarm can be set to be activated during close
contact (MAKE) or during open contact (BREAK)
can be set from the menu.
• The alarm signal should last for at least 500
msec. If the alarm signal is short, it may not be
recognized.
● Input conditions
• Connect non-voltage a contact or open collector
output circuit
(For details on how to set polarities, please refer to
"Instructions (Setting)".)
• Low level terminal current below 1 mA
• High level terminal current 3.3 V

LAN cable
• When connecting to a switching hub:
Use a straight cable.
• When connecting to a computer:
Use a crossing cable.
370
• A 100-meter or less length and Category-5 or higher
grade STP (shielded) cable is recommended.
Note
• The crossing cable may not be used for some
computer models. Check the LAN specifications of
the computer when you directly connect this unit to
the computer.
● Alarm I/O cable
• A 50-meter or less length shielded cable is
recommended.
• Attach the supplied ferrite core to the cable.

(VN-H257VPU)
Alarm output
Connect an alarm device, indicator, lighting, buzzer or
other device.
• An alarm output signal is an open collector output.
You can configure the menu to set the alarm to
sound when contacts short circuit (MAKE) or
when the contacts are open (BREAK). (Pressure
resistance lower than 16V, 30 mA)
• This terminal has different polarities. The output
voltage at the positive terminal must always be
higher than the output voltage at the negative
terminal. Otherwise, the circuit may be damaged.
● Output conditions
• Equivalent to NPN open collector output
(For details on how to set the output logic, please
refer to "Instructions (Setting)".)
• Safe excitation voltage: DC16 V or lower
• Allowable surge current: 30 mA
• Momentary (100 ms to 5000 ms) output
(For details on how to set the time, please refer to
"Instructions (Setting)".)

Troubleshooting

Causes and Countermeasures
The image output may be turned Off on Internet Explorer.
Check the monitor output setting.
• Check the MIC connection.
☞
• Is the audio setting turned off? (
• If the monitor image output is turned ON, a lower frame rate is set for
network images.
• If you turned the monitor image output to OFF, set the frame rate
☞
again.( "Instructions (Setting)" - "Internet Explorer Setting" -
"Encoding Page")
Is the focus adjustment gear engaged? Check the location of the catch.
