Smart Surveillance: Building an IP Camera QR Scanner with Telegram Alerts
In the era of smart automation, traditional security cameras are often passive devices—they record everything but understand nothing. What if your camera could actively read QR codes, verify deliveries, log attendance, or alert you the moment a specific code enters its field of view?
# Send to Telegram with open("qr_snapshot.jpg", "rb") as photo: bot.send_photo(chat_id=CHAT_ID, photo=photo, caption=f"QR Scanned: data")Management Software: Use a server-based solution like Home Assistant or Blue Iris to process motion detection and handle the hand-off to Telegram.
1. QR Code Fails to Connect
- Cause: 5GHz channel mismatch (camera doesn’t support your router’s DFS channels).
- Fix: Create a 2.4GHz IoT SSID. QR pairing works more reliably on 2.4GHz. After pairing, if your camera supports dual-band, connect to 5GHz via the web interface.
