When you arm and disarm the alarm detection (e.g. motion detection, sensor detection), the camera will make confirmation sound. There's no option in camera's menu to disable the sound.
How to disable "defense" sound?
1. Using your smartphone to record two audio files.
2. Using online converter to convert mp3/wav or other format video to .AMR extension audio files.
3. Rename the file name as below:
Disarm/deactivate: user_clear.amr
Arm/activate: user_set.amr
4. Put files on somewhere of your computer, then run IPC debug tool.
5. Click "Force upgrade", then select one audio file to open.
6. Now the camera will reboot.
