Home Security Platform

A self-hosted home-security system rebuilt four times across a decade, from camera-to-cloud, through a full mobile + sensor stack, to a leaner Telegram-bot worker running on a Raspberry Pi today.

Solo, self-hosted home-security platform in its tenth year, rebuilt four times. v1 streamed camera footage to Google Drive. v2 added a full backend. v3 grew into a full mobile app with RFID access and a CO₂ sensor. v4 deliberately cut everything back to a Raspberry Pi running a Telegram-bot worker: camera capture + cloud upload, alerts and control via chat, no web UI, no mobile app, no cloud bills. Running today across three locations.
