Uploading a file from the local computer
MOBOTIX cameras support the OPUS, WAV and AL formats. Opus encoding is a file format for lossy compression of audio data with the lowest possible latency. This format is ideally suited for real-time applications on the Internet and covers the entire range of human hearing. The camera expects an opus audio file with one channel (mono) and a frequency range of 16 kHz.


1. The easiest way to convert your files to Opus format is to use the following online service: http://audio.onlineconvert.com/convert-to-opus 36. Select the file you want to convert by pressing the “Browse” button then set the option as follows: 128 Kbps, 16000 Hz, mono. Press “Convert file” to start the conversion.





2. The conversion should take only a few seconds. Save the file to your computer.






3. Go to the page Admin Menu > Manage Audio Messages
4. Select “.opus (Opus audio file, mono, 16KHz)” from the “File Type” drop down menu. Press “Browse”, locate the converted file and press ok. Click on “Upload” to transfer the file to the camera.


5. Now you can playback the file to check the result. Press “Play” to play it through the camera’s loudspeaker or select the Outgoing Call Profile and click on “Call and Play” to play it through a phone.
