| Component | Notes | |-----------|-------| | | Decoding QR on every frame is heavy. Use frame skipping (every 30 frames) or motion detection first. | | Multiple QRs | Handle case of multiple codes in one frame. | | Lighting | QR detection fails in poor light; ensure camera has good illumination. | | Distance/Resolution | QR must occupy enough pixels (~100px per module). Adjust camera zoom/position. | | Security | Telegram bot token should be stored as env var, never hardcoded. | | Latency | RTSP + processing + Telegram API = ~2–5 seconds delay typical. |

: Ensure Telegram has permission to access your camera in your phone's system settings. Are you trying to set up a security camera to send alerts to Telegram, or are you having trouble scanning a code to log in?

This is a great weekend project for IoT enthusiasts. You'll need an ESP32-CAM board, a USB programmer, and some basic electronic components like a relay and a push button. The instructions in the robu.in PDF guide highlight how to build a smart door lock system with an ESP32-CAM, but the core concept applies to any security camera setup.

Captures video streams and detects motion. It must support standard streaming protocols like RTSP (Real-Time Streaming Protocol) or ONVIF.

If routing camera alerts to a Telegram group chat, modify the bot's permissions using @BotFather to disable "Privacy Mode." This ensures the bot only reads commands explicitly directed to it, while preventing unauthorized users in the group from altering camera settings via reverse commands.
