Your old phone.
Now it watches the door.

Mount the phone you no longer use, plug it in, and point it at the entrance. When someone walks in, Webcam Security sounds a siren, saves photos and a short video, and sends them straight to your Telegram — before anyone can take the phone.

The story behind Webcam Security

Webcam Security was built for a rented apartment and a drawer full of old phones.

Every time I left a place for a few days I wondered whether anyone was coming in. Security cameras wanted a monthly fee, a cloud account, and a copy of every frame of my home on their servers. Meanwhile a perfectly good phone sat unused, with a camera, a speaker, and Wi-Fi.

So I built an app that runs entirely on that phone. It watches for movement on the device itself, and the only place the evidence goes is a Telegram bot that you create and control. No servers of mine in the middle, no subscription, no account. You pay once, and the camera is yours.

What it does

Detects movement on the device The camera is analyzed on the phone itself. Gradual light changes, like sunrise, are filtered out. On iPhone, Apple's Vision framework also recognizes people, on the device.
Siren that scares intruders A loud alarm plays when someone is detected. You can turn it off or keep it silent in Settings.
Photo burst and short video Three photos, keeping the sharpest one, plus an optional 15-second clip in standard quality. No audio is ever recorded.
Alerts to your Telegram Evidence goes directly from the phone to your own bot, so it is safe even if the phone is taken.
PIN-protected disarm Arming is one tap. Disarming, and silencing the siren, always requires your PIN.
Built for days away Runs with the screen off on Android, or open in a darkened stealth mode on iPhone. Manages storage automatically and backs off when the phone gets hot.
One-time purchase: US$19.99. No subscriptions, no ads.

Pay once on Google Play (Android) or the App Store (iPhone) and every feature is yours — no monthly fee, no In-App Purchases, no ads, no account. Local prices and taxes are shown by the store in your country. Each store sells its own version.

Not a professional alarm or monitoring service Webcam Security is a personal tool. It does not contact the police or any monitoring center, and detection can fail (darkness, battery, network, the system closing the app). You are responsible for recording only where it is legal and for informing people as your local law requires.
