Protect Baby 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.

Currently Protect Baby Monitor builds against Android SDK 17. It may work for lower SDK versions, but this has not been tested.

The current version of Protect Baby 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

At the time this project was started there was no obvious open source solution for a baby monitor for Android. There are both free and paid options available for Android, including:

If there is any interest in improving this open source baby monitor, kindly submit a pull request with proposed changed.
