`
In the case you access the web viewer and select an external microphone as the audio input sources in <Video & Audio> -
<Audio setup>, the following specifications are recommended:
-
Frequency range: 40-16,000 Hz
-
Impedance: 1,500 Ω
-
Sensitivity: -40±3 dB (7.1-14.1 mV)
`
In any of the following cases, sound classification performance may be degraded or malfunction:
-
If gunshot sounds are heard continuously in a short interval (e.g. machine gun sound) rather than a one-time gunshot
sound
-
If the noise is too loud for the noise and the target sound to be distinguished
-
If two or more of different sounds are registered simultaneously
-
If the sound classification is applied while using the noise removal function in a quiet place
-
If the source of clapping sounds or screams is close to the camera (within 1 meter)
-
If a sound that does not belong to any of the sound classification categories (airplanes sound, siren sound, etc.) is loudly
heard all of sudden
-
If external microphone does not meet the recommended specifications
Connecting to the I/O port box
Connect the Alarm I/O cable to the corresponding port of the port box.

Sensor
• ALARM-IN : Used to connect the alarm input sensor.
• ALARM-OUT : Used to connect the alarm output signal.
• GND : Common port for alarm in/output signal.
J
`
If devices (e.g., flashing light and siren) that exceed the voltage and current specifications are connected by using the open
collector method, it may cause malfunction.
Refer to the “Alarm Out Wiring Diagram” when connecting devices that exceed the voltage and current specifications. (page 37)
To connect the external sensor
Connect one strand of each signal line (2-strand) of the sensors to the [ALARM IN] port, and connect the
other strand to the [GND] port.
