Audio Codec
- Audio In : G.711 PCM (Bit Rate: 64kbps / Sampling Frequency: 8kHz), G.726 ADPCM (Bit Rate:
16Kbps, 24Kbps, 32Kbps, 40Kbps / Sampling Frequency: 8kHz), AAC (Bit Rate: 48Kbps / Sampling
Frequency: 16kHz)
- Audio Out : G.711 PCM (Bit Rate: 64kbps / Sampling Frequency: 8kHz)
~ Full duplex Audio
~
Audio in : Selectable (microphone/Line-in), Supported voltage: 2.5VDC (4mA), Input impedance: 2K Ohm
~
Audio out : Line-out (3.5mm mono jack), Maximum output: 1Vms, Line out impedance : 600Ω
J ` 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

Color Function Description
BROWN : ALARM I/O 1
ORANGE : ALARM I/O 2
ALARM I/O 1,
ALARM I/O 2
These two ports are configurable from the web viewer, as they can be
used as Alarm in or Alarm out
※ Alarm I/O changes can be made through the Webviewer setup.
RED DC 12V/50mA
This pin supplies a continuous 12VDC output with a maximum
amperage of 50mA
BLACK GND It is a ground terminal.
