General Audio
Setting the volume of the input/output audio, the type of microphone, and the operation of the built-in microphone for audio
input.
[Audio Input]
Select whether to use audio input from the microphone. If [Enable] is selected, it is possible to use functions related to
audio input such as [Audio Server] > [Audio Transmission from the Camera] (P. 93) or [Detection] > [Audio Detection] >
[Volume Detection] > [Volume Detection Event] (P. 104).
If you select [Disable] and click [Apply], the following settings are locked and audio input functions are disabled.
– [Audio Server] > [Audio Transmission from the Camera] > [Disable]
– [Server] > [RTP Server] > [RTP Stream 1] to [RTP Stream 5] > [Audio Transmission] > [Disable]
– [Detection] > [Audio Detection] > [Volume Detection] > [Volume Detection Event] > [Disable]
[Input Volume]
Set the input volume from the microphone.
This is applied when [Audio Input] is set to [Enable].
[Current Volume Level]
When [Audio Input] is set to [Enable], the current volume level is displayed on the status bar.
[Low-Cut Filter]
When [Audio Input] is set to [Enable], select whether to use the function of cutting the low frequency range of the input
audio. By selecting [Enable], it is possible to reduce noise, such as wind noise, that occurs when the wind hits microphone,
making it easier to hear conversations.
By selecting [Disable], environmental noise, such as generated by traffic or crowd, are inputted more accurately.

Important
• Video and audio can be delivered to up to 30 clients. However, when there are many clients or they are connected to the camera over
an SSL/TLS connection, when the audio is received from the camera, the video frame rate may decrease or the audio may be
interrupted.
• The video and audio may not be synchronized.
• If the [Input Volume] or [Low-Cut Filter] setting is changed after setting volume detection (P. 104), review the detection setting.
• The audio may be temporarily interrupted, depending on the performance of the computer and the network environment.
• The audio may be interrupted if anti-virus software is enabled.
• When communication is temporarily interrupted due to reseating the LAN cable, the audio is interrupted. If this occurs, reconnect from
the Viewer.
• The volume, sound quality, etc., may change depending on the characteristics of the microphone used.
• Use a speaker with an amplifier to connect to the camera (refer to the “Installation Guide”).
