The problem
What people put up with
Smart baby monitors cost a lot, need accounts, and send a live feed of a child's bedroom to someone else's servers. Meanwhile most families have an old phone in a drawer.
The odd angle
The insight
The hardware already exists and the network is the home Wi-Fi. A peer-to-peer connection keeps the stream inside the house and removes the subscription completely.
The approach
How we built it
- 1
Two roles, one app
The same app runs as either the baby station or the parent station. Pairing takes seconds, and either phone can switch roles.
- 2
Peer-to-peer by default
Media goes directly between the devices over WebRTC. No account, no cloud video storage.
What it does
Features
- Baby and parent modes
- Direct WebRTC audio and video
- Works on iOS and Android
- Dark, low-glow interface for night use
The hard parts
What fought back
Phones that want to sleep
Mobile operating systems close background apps to save battery. A monitor has to stay awake all night without overheating, which is the main thing we're working on now.
What's next
On the roadmap
- Cry detection on the device
- Low-bandwidth audio-only night mode
