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.

Connect non-voltage a contact or open collector 
output circuit
(For details on how to set polarities, please refer to 
“Instructions (Setting)”.)

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.

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

“Instructions (Setting)”.)

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.

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 
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.

A 50-meter or less length shielded cable is 
recommended.
Attach the supplied ferrite core to the cable.

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 

system, etc.

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] (

No monitor image is output.

The image output may be turned Off on Internet Explorer.
Check the monitor output setting.

The external mic sound is not heard.

Check the MIC connection.
Is the audio setting turned off? (

Movement of network image is not 
smooth

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.(
