- Create an account and log in.
- Follow the in-app instructions to add your SEHMUA RBX-H12 camera. This typically involves scanning a QR code on the camera or manually entering its device ID.
- Ensure your camera is powered on and within an area with 4G LTE coverage during the pairing process.
4.3 Mounting the Camera
The camera offers two primary mounting methods:
- Direct Tree Mount: Use the provided strap to secure the camera directly to a tree. Ensure the solar panel is positioned to receive maximum sunlight.
