An Open Source Child Monitor for Android
Child Monitor allows two Android devices to act as a baby monitor. The first device, left in the room with the baby, will advertise itself on the network and stream audio to a connected client. The second device, with the parent, will connect to the monitoring device and receive an audio stream.
The project is a fork of Protect Baby Monitor which is declared as "on hiatus" by its developer.
Child Monitor works on Android 5.0 (Lollipop) and newer, i.e. Android SDK 21.
The current version of Child Monitor is rudimentary at best. It is capable of successfully advertising itself on the network, allows clients to connect, and streams audio. Room for improvement includes:
- Robust usage of the AudioTrack API
- Handle dropped packets gracefully
- Use of GSM when no internet connectivity is available
At the time this project was forked from Protect Baby Monitor there was no obvious open source solution for a baby monitor for Android in F-Droid.
To use this App with two phones that are not connected to the same WIFI network a VPN can be used. Since auto discovery is not supported in this scenario the child device's ip address must be entered manually in the parent device. You can find the VPN ip address among the listed ip addresses on the child device once the listen mode was entered. The child device will usually bind to port 10000 (unless that port is already taken by another application).
