Troubleshooting
- No Cellular Connection:
- Ensure you are using a SanDisk brand SD card. Some users have reported connectivity issues with other brands.
- Verify AT&T cellular coverage in the camera's location using the app's coverage maps.
- Check battery levels; low batteries can affect cellular transmission.
- Confirm your data plan is active and has sufficient data.
- False Alarms/Excessive Photos:
- Adjust the camera's sensitivity settings via the app.
- Ensure the camera is not pointed at areas with excessive moving foliage or objects that could trigger the sensor (e.g., branches swaying in wind).
- Moisture Inside Camera:
- Ensure the camera casing is always securely latched when deployed outdoors.
- If moisture is present, open the camera in a dry environment and allow it to air out completely before re-sealing.
- App Deployment Issues in Low Signal Areas:
- If you are in an area with weak cellular signal, perform the initial camera deployment and setup at your home or an area with strong signal. You can then update the camera's location in the app once it is deployed in the field.
- Short Battery Life:
- Ensure you are using fresh, high-quality alkaline or lithium AA batteries.
- Frequent cellular transmissions, video recording, and cold temperatures can reduce battery life. Adjust settings to optimize.
