6. Troubleshooting
If you encounter issues with your Hiseeu C90B camera, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Camera not powering on. | Low battery or power button not pressed long enough. | Charge the camera using the USB cable. Press and hold the power button for 5-8 seconds. |
| Cannot connect to WiFi. | Incorrect WiFi password, 5GHz network, or weak signal. | Ensure you are connecting to a 2.4GHz WiFi network. Double-check the password. Move the camera closer to the router. |
| SD card not detected. | Improper insertion, incompatible card, or card corruption. | Ensure the SD card is inserted correctly. Try formatting the SD card via the app (this will erase data). Use a compatible SD card (up to 256GB). |
| Frequent false motion alerts. | High sensitivity setting, environmental factors (e.g., swaying branches, insects). | Adjust the motion detection sensitivity in the EseeCloud app. Define specific detection zones to exclude irrelevant areas. |
| Alexa integration issues. | Incorrect skill setup, network issues, or device not linked. | Ensure the correct Hiseeu skill is enabled in the Alexa app. Verify both devices are on the same network. Relink the camera in the Alexa app if necessary. |
