The workflow relies on a bridge application, custom firmware, or a specialized network video recorder (NVR) that connects the camera's video stream to the Telegram API.
Some custom firmwares expect raw text. Create a text string exactly like: BOT_TOKEN:7236457283:AAHdqTcvCH1vGWJxfSeofSAs0K5PALDsaw;CHAT_ID:123456789 Generate a QR code from this plain text.
Used for real-time signaling. When the camera detects motion, it sends a lightweight ping to the cloud server.
