<p>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. Thus, it is not surprising that baby monitors are one of the fastest growing baby product category. However, many of the baby monitors available in the market are rather dumb and expect the parents to keep looking at the video stream or listen to the audio. This how-to will help you create a smart baby monitor on a budget and integrate it with Home-Assitant. Instead of relying on the poor quality baby monitor speakers, we use our existing speakers (e.g., Sonos). We can also send notifications (with pictures) to avoid constant monitoring of the feed.</p>

<h3><a class="title-link" name="setup" href="#setup"></a> Setup</h3>
<p>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 our Home-Assistant with <code class="highlighter-rouge">ffmpeg -f alsa -i hw:1,0 -vn -f rtp rtp://236.0.0.1:2000</code> over multicast. We can set <code class="highlighter-rouge">input</code> option on Home-Assistant side to <code class="highlighter-rouge">rtp://236.0.0.1:2000</code> in same network.</p>

<p>We can optimize the audio stream for human voice by using a highpass filter with 300Hz and a lowpass filter with 2500Hz. 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 <code class="highlighter-rouge">extra_arguments</code>). For icecast2 we convert the audio stream to mp3 with samplerate of 16000 (which is the minimum for Sonos speakers). We use <code class="highlighter-rouge">peak</code> to set the threshold for noise detection, where 0 dB is very loud and -100 dB is low.</p>

### <a class='title-link' name='setup' href='#setup'></a> 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 our Home-Assistant with `ffmpeg -f alsa -i hw:1,0 -vn -f rtp rtp://236.0.0.1:2000` over multicast. We can set `input` option on 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 icecast2 server for playing over speakers integrated with Home-Assistant (e.g., 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.
<p class='note'>
We change the platform name for binary sensor in 0.38 from `ffmpeg` to `ffmpeg_noise`. Also all service going to component and was rename from `binary_sensor.ffmpeg_xy` to `ffmpeg.xy`.
</p>
On Raspbian Jessie, you can setup [ffmpeg](/components/ffmpeg) and install a [icecast2](http://icecast.org/) server using:
```bash
$ sudo echo "deb http://ftp.debian.org/debian jessie-backports main" >> /etc/apt/sources.list
$ sudo apt-get update
$ sudo apt-get -t jessie-backports install ffmpeg
$ sudo apt-get install icecast2
```
We setup a icecast mount point for our babyphone and update `/etc/icecast2/icecast.xml`:
```
<mount>
<mount-name>/babyphone.mp3</mount-name>
<stream-name>Babyphone</stream-name>
<username>stream_user</username>
<password>stream_pw</password>
</mount>
```
Now we can add the noise sensor to Home-Assistant. We can 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 300Hz and a lowpass filter with 2500Hz. 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.
```yaml
binary_sensor:
- platform: ffmpeg_noise
input: rtsp://user:pw@my_input/video
extra_arguments: -filter:a highpass=f=300,lowpass=f=2500,volume=volume=2 -codec:a libmp3lame -ar 16000
output: -f mp3 icecast://stream_user:stream_pw@127.0.0.1:8000/babyphone.mp3
initial_state: false
duration: 2
reset: 60
peak: -32
```
We use the option `initial_state` to prevent the ffmpeg process from starting with Home-Assistant and only start it when needed. We use an `input_boolean` to control the state of ffmpeg services using the following automation.
```yaml
input_boolean:
babyphone:
name: babyphone
initial: off
automation:
- alias: 'Babyphone on'
trigger:
platform: state
entity_id: input_boolean.babyphone
from: 'off'
to: 'on'
action:
service: ffmpeg.start
entity_id: binary_sensor.ffmpeg_noise
- alias: 'Babyphone off'
trigger:
platform: state
entity_id: input_boolean.babyphone
from: 'on'
to: 'off'
action:
service: ffmpeg.stop
entity_id: binary_sensor.ffmpeg_noise
```
### <a class='title-link' name='trigger-a-alarm' href='#trigger-a-alarm'></a> Trigger a alarm
Now we can make a lot stuff. Here is a simple example of an automation what should be possible with Sonos speakers.
```yaml
automation:
- alias: 'Babyphone alarm on'
trigger:
platform: state
entity_id: binary_sensor.ffmpeg_noise
from: 'off'
to: 'on'
action:
- service: media_player.sonos_snapshot
entity_id: media_player.bedroom
- service: media_player.sonos_unjoin
entity_id: media_player.bedroom
- service: media_player.volume_set
entity_id: media_player.bedroom
data:
volume_level: 0.4
- service: media_player.play_media
entity_id: media_player.bedroom
data:
media_content_type: 'music'
media_content_id: http://my_ip_icecast:8000/babyphone.mp3
- service: light.turn_on:
entity_id:
- light.floor
- light.bedroom
data:
brightness: 150
- alias: 'Babyphone alarm off'
trigger:
platform: state
entity_id: binary_sensor.ffmpeg_noise
from: 'on'
to: 'off'
action:
- service: media_player.sonos_restore

We need an IP-camera that can capture sound in the baby's room.

We can set `input` option on Home-Assistant side to `rtp://236.0.0.1:2000` in same network.

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 icecast2 server for playing over speakers integrated with Home-Assistant (e.g., 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.

We change the platform name for binary sensor in 0.38 from `ffmpeg` to `ffmpeg_noise`. Also all service going to component and was rename from `binary_sensor.ffmpeg_xy` to `ffmpeg.xy`.

Now we can add the noise sensor to Home-Assistant. We can 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.

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 300Hz and a lowpass filter with 2500Hz. 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.

We use the option `initial_state` to prevent the ffmpeg process from starting with Home-Assistant and only start it when needed. We use an `input_boolean` to control the state of ffmpeg services using the following automation.
