Audio Input/Output Terminals
Each audio input/output terminal has one input system and one output system.
Connecting the camera to an audio input/output device such as a microphone or a speaker with an amplifier allows you to send/receive audio through the viewer.
Use the included audio interface cable to connect audio input/output devices to the camera.
Use the 3.5 mm ( 0.14 in.) monaural mini-jack connector to connect an audio output device with the audio interface cable.
The long end (has cable marker) from the bifurcation point in the cable corresponds to the audio output terminal. The short end (does not have cable marker) from the bifurcation point in the cable corresponds to the audio input terminal.
Audio Input Dual LINE IN/MIC IN (monaural input)
Although the camera has a single audio input system, it supports two types of microphone input:
LINE IN and MIC IN. Before using the audio input, change the [Audio Input] on the Setting Page (see “Operation Guide” > “Audio Input”). LINE IN is selected by default.
Input terminal: 3.5 mm ( 0.14 in.) mini-jack (monaural)
• Dynamic MIC IN - Input impedance: 1.75 k? } 20%
* Supported microphones: Output impedance: 400? – 600?
• Condenser MIC IN - Input impedance (microphone bias resistance): 2.2 k? } 20%
Microphone power supply: plug-in power (voltage: 1.8 V)
* Supported microphones: Condenser microphones with plug-in power support
• LINE IN
Input level: Max. 1 Vp-p
* Use a microphone with an amplifier.
? Audio Output Terminal LINE OUT (monaural output)
Connect the camera to a speaker with an amplifier. Audio can be sent to the speaker from Viewer.
Output terminal: 3.5 mm ( 0.14 in.) mini-jack (monaural)
Output level: Max. 1 Vp-p
* Use a speaker with an amplifie
Important
• Using the wrong settings in [Audio Input] may damage the camera and/or microphone. Be sure to configure settings correctly.
• Microphone characteristics may affect volume and sound quality.
• Audio may be interrupted depending on PC characteristics and network environment.
• Video and audio can be streamed to up to 30 clients. However, audio may be interrupted when streaming to many clients or using SSL.
• Audio may be interrupted when using antivirus software.
• Connecting and disconnecting the LAN cable interrupts the audio. Use the viewer to reconnect
