by the crib — a spare phone, tablet, or laptop
with you — your phone or laptop

Any two devices — two phones, or a phone and a laptop, or a tablet and a phone. Prop one by the crib as the Cam device (a laptop webcam works fine here); keep the other with you as the View device — a phone or a laptop both watch happily. One shows a short number, you type it into the other, and the picture then travels straight device-to-device through your router. A tiny matchmaker introduces the pair by that number; it never sees the video or sound.

How it connects — four plain steps
1Open it on both

Open babycamly on both devices. Make sure they share the same wifi — that's the only thing they need in common.

Cam View 2Pick a job on each

On the one by the crib, tap Cam device. On the one you hold, tap View device. That's it — each now knows its part.

One device shows a short code — type it into the other. That's it. Nothing to aim a camera at, nothing to paste.

● live 4You're watching

The picture appears on your View device. Leave the Cam device propped up and plugged in, and you're set for the night.

Honest notes: once linked, two-device mode carries video and sound straight between the pair — a tiny matchmaker only introduces them by that short code and never sees the picture. The trades: the introduction step needs a moment of internet on each device; both devices must stay awake and plugged in; iPhones need one tap before sound plays; guest wifi with client isolation blocks the link (pairing help); and across cellular without STUN it simply won't connect — by design, not by accident.

We had a drawer full of old phones and bought a baby monitor anyway — a plasticky thing with an app that wanted our email and, we later realised, streamed our nursery to someone's cloud. So we built the honest version: one phone by the crib, watching and alerting, nothing uploaded. Then a reader asked the obvious question — "can't the second old phone in the drawer be the parent unit?" — and it nagged at us, because the answer was almost yes. The phones only needed a way to find each other first. We tried making you scan codes between screens; parents told us plainly it was fiddly. So now one phone shows a short number, you type it into the other, and a featherweight go-between introduces the two by that number — the picture itself still crosses only your router, and the plasticky monitor is still in its box.

Setting it up

  1. Cam device: prop it so it sees the crib, plugged in, tap Cam device, allow camera + mic. A phone, tablet, or a laptop with a webcam all work. It puts a short code on screen.
  2. View device: tap View device and type that number into the box, then tap connect. Spaces are fine, and the keypad is numbers-only.
  3. Let them meet: the two devices trade their connection details by that number and link up on their own — usually within a couple of seconds. No reply to carry back this time.
  4. Watch: tap 🔊 to unmute (browser rule), ⛶ for full screen, set your alert thresholds, and pocket the View device — it beeps, flashes and vibrates when the room stirs. Hold 🎙 to shush from afar.

Why babycamly

Monitor questions

Where does the video actually travel?

From one phone to the other through your router, encrypted (WebRTC is always DTLS-encrypted). Only the setup handshake — the short room code and the connection details behind it — passes through the little matchmaker; the picture and sound never do.

The devices won't connect.

Same wifi? Guest networks often isolate clients from each other — that's the #1 cause. Move both to the main wifi. Full walkthrough: pairing help.

Can I watch from a different network?

Flip on the different networks switch before pairing: it uses a public STUN server to discover addresses (revealing your IP to it). Works for many home-to-office pairs; strict mobile carriers may still block it, and without a relay server that's the honest end of the road.

It keeps false-alarming.

Raise the thresholds just above the room's resting bars — on the View device in two-device mode, on the Cam device in solo mode. A fridge hum or headlights need about a minute of tuning to ignore.

Battery?

Camera, mic and a live stream are hungry on both ends. Keep both devices on chargers; the wake-lock keeps their screens from dozing.
