Baby Monitor Camera: Cry Alert

Baby Monitor turns two Android phones into a private video baby monitor with cry detection. Put a spare phone by the crib as the baby camera, then watch, listen and talk back from your own phone over your home Wi-Fi. No account, no subscription, no cloud and no baby camera to buy.

— How it works —
1. On the phone in the nursery, tap Camera Mode.
2. Open Baby Monitor on your phone. It finds the camera on your Wi-Fi by itself.
3. Tap Watch. You're live, with no codes to type and nothing to sign up for.

— Watch on any device —
• Up to 3 people can watch at once, on phones or in a browser.
• No app on the other device? Scan the QR code on the camera phone to watch in the browser of an iPhone, iPad or laptop on the same Wi-Fi. Android phones with Baby Monitor installed can open the app straight from the code.
• "Watching now" on the camera phone shows who is connected, and you can disconnect anyone.

— Cry alerts —
• The camera phone listens for crying and alerts you with a notification, even when your screen is off.
• Optional: let cry alerts sound even in Do Not Disturb.
• Choose the detection sensitivity, or turn detection off and use it as an audio baby monitor.

— Sound history —
• A live sound meter, and a chart of the last 10 minutes or the last hour with each cry marked, so you can see when your baby stirred or cried while you were busy.

— Video and talk back —
• Smooth live video at up to 30 frames per second that adapts to your Wi-Fi and phone.
• Night mode brightens a dark room. Turn the camera phone's light on or off, or switch between its cameras, from your phone.
• Hold to talk: soothe your baby from the next room (in the Android app).
• Audio-only mode saves battery and data. Camera settings are shared by everyone watching.

— Made for the night —
• Keeps running with the screens off, and reconnects on its own if the Wi-Fi drops. If the camera stays unreachable, you get an alert.
• See the camera phone's battery level, with a low-battery alert at 20% and 10%.
• Dark, calm screens with big buttons.

— Private by design —
• Video and audio go directly from phone to phone over your Wi-Fi, encrypted. They never pass through our servers or any cloud, and nothing is recorded.
• No account and no ads. Each phone asks only for what it needs: the parent's phone never asks for the camera.
• All we receive is anonymous usage statistics and crash reports, so we can fix bugs and improve the app, plus any feedback you choose to send.

— What you need —
• Two Android phones (Android 8 or newer) on the same Wi-Fi, or one Android phone as the camera and any phone, tablet or computer with a browser to watch.
• Works on your home Wi-Fi only: both devices must be on the same network. Watching from outside your home isn't supported.
• An old phone makes a great baby cam or nanny cam. Keep it plugged in for long nights.

Baby Monitor is not a medical device and doesn't replace adult supervision.
