5. Troubleshooting
If you encounter issues with your OBO HANDS Video Intercom System, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No image on monitor / Camera blinking | Loose wiring connection, power issue, camera fault. | Check all 4-wire connections between the outdoor unit and monitors. Ensure power adapters are securely plugged in. Power cycle the system by unplugging and re-plugging the power adapters. |
| Monitor screen is pixelated or distorted | Poor cable quality, excessive cable length, signal interference, monitor issue. | Ensure you are using high-quality Cat5e/Cat6 cables within the 100m limit. Check for strong electrical interference near the cables. Try power cycling the monitor. If the problem persists, contact support. |
| No audio or poor audio quality | Microphone/speaker obstruction, loose wiring, volume settings. | Check for any obstructions on the microphone or speaker of both units. Verify wiring connections. Adjust volume settings on the indoor monitor. |
| Cannot connect to Tuya App | Incorrect WiFi network (not 2.4 GHz), incorrect password, network issues, app permissions. | Ensure your smartphone and the intercom system are connected to a 2.4 GHz WiFi network. Double-check the WiFi password. Restart your router. Verify that the Tuya app has necessary permissions on your smartphone. |
| Remote unlock not working | Electric lock not connected, incorrect wiring, lock malfunction. | Verify that the electric lock is correctly wired to the outdoor unit. Check the lock's power supply and functionality independently. |
