One of the hardest part of being a parent is keeping a constant eye on the baby to make sure that baby is doing well.

Obviously, you can use the setup as a general purpose surveillance system to monitor noise in the whole house.

Setup

-

We need an IP camera that can capture sound in the baby’s room. It is also possible to use a Raspberry Pi with a microphone and send the audio to Home Assistant with ffmpeg -f alsa -i hw:1,0 -vn -f rtp rtp://236.0.0.1:2000 over multicast. We can set the input option on the Home Assistant side to rtp://236.0.0.1:2000 in same network.

-

Next, we attach a FFmpeg noise binary sensor to our IP camera. The sensor has an output option that allows us to send the output to an icecast2 server for playing over speakers integrated with Home Assistant (eg. Sonos). We can use the binary sensor in our automation. You can ignore the icecast2 setup if you don’t want to play the audio after the noise sensor trigger.

Now we can add the noise sensor to Home Assistant. We lower the sensitivity of the sensor (so that you are not inundated with notifications for every cough of the baby) to 2 seconds using the duration option. The sensor should wait 60 seconds before restoring and it prevent us that a wine break will triggering a new alarm.

We can optimize the audio stream for human voice by using a highpass filter with 300 Hz and a lowpass filter with 2500 Hz. This filters out all non-human sounds such as background noise. We can even add a volume amplifier if the microphone volume is too low (you can remove it from extra_arguments). For icecast2 we convert the audio stream to mp3 with samplerate of 16000 (which is the minimum for Sonos speakers). We use peak to set the threshold for noise detection, where 0 dB is very loud and -100 dB is low.

To control the ffmpeg process of sensor, use the service ffmpeg.start, ffmpeg.stop, ffmpeg.restart.

Motion

FFmpeg doesn’t have a motion detection filter, but can use a scene filter to detect a new scene/motion. You can set how much needs to change in order to detect motion with the option ‘changes’, the percent value of change between frames. If you want a really small value for ‘changes’, you can also add a denoise filter.

Noise

To add FFmpeg with noise detection to your installation, add the following to your configuration.yaml file:

Now you should be able to see what is going wrong. The following list contains some common problems and solutions:

  • [rtsp @ ...] UDP timeout, retrying with TCP: You need to set an RTSP transport in the configuration with: input: -rtsp_transport tcp -i INPUT
  • [rtsp @ ...] Could not find codec parameters for stream 0 (Video: ..., none): unspecified size: FFmpeg needs more data or time for autodetection (the default is 5 seconds). You can set the analyzeduration and/or probesize options to experiment with giving FFmpeg more leeway. If you find the needed value, you can set it with: input: -analyzeduration xy -probesize xy -i INPUT. More information about this can be found here.

USB cameras

For INPUT a valid source is needed. USB camera are an easy way to test your video setup. To get all available USB cameras connected to the system, eg. use the v4l2 tools on a Linux machine.

$ v4l2-ctl --list-devices
+UVC Camera (046d:0825) (usb-0000:00:14.0-1):
