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
