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.
Audio cable connection
Connect the stereo mini jack cable (Φ 3.5).
R channel (MIC IN)
: Connect to a condenser microphone that has a plug-in power system.
L channel (LINE OUT) : Connect to a speaker that has a built-in amp.
Note
• Always connect an external mic to the R channel only. If you plug the mic jack directly into the [AUDIO IN/OUT]
terminal, a loud noise may be generated.
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 (Settings)".)
Low level terminal current below 1 mA
High level terminal current 3.3 V

Troubleshooting

Symptom
Movement of network image is
If the monitor image output is turned ON, a lower frame rate is set for
not smooth
network images.
If you turned the monitor image output to OFF, set the frame rate
again.(
"Encoding Page")
The image output may be turned Off on Internet Explorer.
No monitor image is output.
Check the monitor output setting.
Check the MIC connection.
The external mic sound is not heard.
Is the audio setting turned off? (
Is the focus adjustment gear engaged? Check the location of the catch. (VN-H137U)
Make sure that the lens is compatible with a CS mount.(VN-H57U/VN-H37U)
Lens is out of focus
After initializing the back focus position(
perform focus adjustment again. (VN-H57U)
Rotate the back focusing ring to adjust the focus.(VN-H37U)
Cables
LAN cable
When connecting to a switching hub:
Use a straight cable.
When connecting to a computer:
Use a crossing cable.
A 100-meter or less length and Category-5 or higher
370
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 (VN-H57U)
A 50-meter or less length shielded cable is
recommended.
(VN-H57U)
page 2).
(VN-H57U)
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 (Settings)".)
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 (Settings)".)
