Setting Audio Input/Output
Important
• Video and audio can be distributed to up to 30 clients. However, when there are many clients or they are connected to the camera over
an SSL/TLS connection, the video frame rate may slow down and the sound may drop out if audio reception from the camera is
enabled.
• The video and audio may not be synchronized.
• If the [Input Volume] or [Echo Canceller] ( only) setting is changed after setting volume detection (P. 152) or scream detection
(P. 153), check the detection setting again.
• 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.
• Communication may be temporarily interrupted, cutting off the audio, if the LAN cable is unplugged and plugged in again. 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 (please refer to “Installation Guide”).
