Troubleshooting
- No Connection to App: Ensure the camera is powered on and your device's WLAN is enabled. Verify you are connected to the camera's specific Wi-Fi hotspot (e.g., '305WFHD_xxxxxx'). If issues persist, try restarting both the camera and your mobile device.
- Short Battery Life: Confirm the camera was fully charged before use. Ensure the solar panel is exposed to direct sunlight for optimal charging. Continuous use without solar charging will deplete the battery faster.
- Fuzzy or Distorted Image: Check the camera lens for dirt or obstructions and clean it if necessary. Ensure the camera is securely mounted and not vibrating excessively.
- Camera Shuts Off Unexpectedly: This may indicate a low battery. Recharge the camera. If the issue persists after a full charge, contact customer support.
- Parking Lines Not Adjustable: Refer to the in-app settings for parking line adjustments. If the option is unavailable or unresponsive, ensure your app is updated to the latest version.
