Telegram is a cloud-based messaging app. Why use it for security cameras?
In the context of IP cameras, QR codes serve two distinct purposes:
import cv2 from pyzbar.pyzbar import decode import requestsTELEGRAM_TOKEN = "your_bot_token" CHAT_ID = "your_chat_id"
def send_to_telegram(text, image_path=None): url = f"https://api.telegram.org/botTELEGRAM_TOKEN/sendMessage" data = "chat_id": CHAT_ID, "text": text requests.post(url, data=data) if image_path: url_photo = f"https://api.telegram.org/botTELEGRAM_TOKEN/sendPhoto" files = "photo": open(image_path, "rb") requests.post(url_photo, data="chat_id": CHAT_ID, files=files)
cap = cv2.VideoCapture("rtsp://192.168.1.100:554/stream") # your IP cam URL while True: ret, frame = cap.read() if not ret: break decoded_objs = decode(frame) for obj in decoded_objs: qr_data = obj.data.decode("utf-8") print(f"QR found: qr_data") send_to_telegram(f"QR scanned: qr_data") # Optional: save frame and send as photo cv2.imwrite("qr_capture.jpg", frame) send_to_telegram("Attached QR image", "qr_capture.jpg") # Wait to avoid spam cv2.waitKey(5000) if cv2.waitKey(1) & 0xFF == ord('q'): break
| Component | Notes | |-----------|-------| | Performance | 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. |
The QR code typically contains a JSON string or a serialized string with:
This guide assumes your IP camera supports "Custom API commands" or "HTTP(S) callback" features. If your camera is locked to a proprietary app (like Ring or Arlo), this will not work. You need an open IP camera (Foscam, Hikvision, Dahua, or ESP32-CAM).
