5. Troubleshooting
- Camera Fails to Connect to Wi-Fi:
Ensure you are connecting to a 2.4GHz Wi-Fi network. Verify your Wi-Fi password. Make sure the camera is reset correctly by holding the reset button until two tones are heard. Keep the camera close to the router during initial setup. - App Crashing or Not Functioning:
Ensure your app is updated to the latest version. Try restarting the app or your smartphone. If issues persist, contact customer support. Some users have reported that navigating to the 'security' category within the app helps resolve display issues. - Motion Detection Issues:
The motion detection can be sensitive to light changes. Adjust the sensitivity settings within the app. Be mindful of camera placement to avoid false alerts from moving shadows or light sources. The camera's pan-tilt function may not automatically adjust vertically for motion tracking; it primarily tracks horizontally. - Night Vision Reflection:
If the camera is placed behind a window, the infrared lights may reflect off the glass, obscuring the night vision view. Reposition the camera or disable night vision if this occurs. - Two-Way Audio Static:
Static feedback can occur if the camera is placed too close to other electronic devices (e.g., DVD players, modems, TVs). Try relocating the camera. Ensure the volume settings in the app are adjusted appropriately. - Camera Easily Unplugged:
Ensure the power cable is securely connected and consider securing the cable to prevent accidental disconnection. The camera does not have a backup battery.
