6. Troubleshooting
If you encounter issues with your TMEZON intercom system, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No video feed on monitor/app. | Loose wiring, power issue, camera malfunction. | Check all 4-wire connections. Ensure power adapter is securely plugged in. Restart the monitor. |
| Unstable Wi-Fi connection or app issues. | Incorrect Wi-Fi band (5GHz instead of 2.4GHz), weak signal, app glitch. | Ensure your router is set to 2.4GHz for the device. Move router closer or use a Wi-Fi extender. Reinstall the TuyaSmart app. Follow app setup steps carefully. |
| Two-way audio issues (e.g., one-way communication). | Microphone/speaker obstruction, half-duplex operation, app setting. | Ensure nothing is blocking the microphone or speaker on both units. Note that some systems operate in half-duplex mode (one person speaks at a time). Check app settings for audio options. |
| Motion detection not working or too sensitive. | Incorrect sensitivity settings, environmental factors (e.g., moving trees). | Adjust motion detection sensitivity in the monitor's settings or via the TuyaSmart app. Ensure the camera lens is clean. |
| Doorbell volume too loud/quiet. | Volume settings. | Adjust the volume settings on the indoor monitor. Some outdoor units may have a physical adjustment screw (refer to specific product diagrams if available). |
