- Loop Recording: When the microSD card is full, the camera automatically overwrites the oldest footage, ensuring continuous recording without manual intervention.
3.2 Live View and Playback
- Live View: Access real-time video feed through the connected smartphone app.

- Storage: Store the camera in a cool, dry place away from direct sunlight and extreme temperatures.
5. Troubleshooting
