About this app

No Cloud, 100% Local On Device Privacy. Turn spare Android phones into a complete AI security & monitoring system. HumanDetector AI uses on-device AI to detect actual people in real time — not just motion — and gives you four ways to use it.

FOUR MODES, ONE APP

🛡️ Security Camera — Point a spare phone at your door, window, or room. When a real person is detected it sounds an alarm, saves timestamped photos, and sends instant alerts to your other phone and to Telegram.

📺 Live Viewer — Turn a second phone into a remote monitor. Watch your cameras live (real-time video), get instant alerts, talk back through the camera, and send remote commands — from the next room or anywhere in the world (with Tailscale).

👶 Baby Monitor — FREE FOREVER — Leave a phone in the baby's room. The moment it hears crying it alerts your phone and opens live video automatically, with push-to-talk to soothe your baby (or sends a short clip to Telegram). No cost, no trial clock — ever.

🚗 Dashcam — Continuous drive recording with a loop buffer, automatic crash lock, and GPS speed/location overlay.

SECURITY CAMERA FEATURES

PRIVACY FIRST — ZERO DATA COLLECTION
All AI runs entirely on your device. No cloud, no servers, no accounts, no tracking. Photos and video go only to your own phone, your own private viewer, or your own Telegram bot. We collect nothing. Ever.
