6. User Tips

• Camera Monitoring: You can check video cameras connected to your KERUI W204 system directly through the Tuya Smart mobile application. Ensure your cameras are properly paired and configured within the app for remote viewing.
• Scheduled Arming: Utilize the scheduled arm/disarm function to automate your security routine. This prevents forgetting to arm the system when leaving or disarm it upon returning.
• Battery Management: Regularly check the battery status of your wireless sensors and remote controls. Replace batteries promptly when a low battery reminder is issued to ensure continuous protection.
• Signal Strength: When installing wireless sensors, try to place them within the recommended wireless distance (e.g., 100m in open area) and avoid major obstructions that could interfere with the signal.

7. Troubleshooting

7.1. System Not Responding

• Check Power: Ensure the alarm panel is properly connected to power and the ON/OFF switch is in the 'ON' position.
• Backup Battery: If there was a power outage, check if the backup battery is charged.
• Restart: Try turning the panel off and on again.

7.2. Sensors Not Triggering Alarm

• Pairing: Verify that the sensor is successfully paired with the alarm panel (refer to Section 2.4).
• Battery: Check and replace the sensor's battery if it's low or depleted.
• Placement: Ensure the sensor is installed correctly and within range of the alarm panel. For door/window sensors, ensure the two parts are aligned and close enough. For PIR sensors, ensure no obstructions block the detection area.
• Arming Mode: Confirm the system is in an armed mode (e.g., 'Arm' or 'Home Arm') where the specific sensor is active.

7.3. No App Notifications or Remote Control

• Wi-Fi/4G Connection: Ensure the alarm panel has a stable Wi-Fi or 4G/GSM connection. Check the network status indicator on the panel.
• App Status: Verify your smartphone has internet access and the Tuya Smart app is running and logged in.
• SIM Card: If using 4G/GSM, ensure the SIM card is active, has credit (if prepaid), and has a strong signal.
• App Permissions: Check that the Tuya Smart app has necessary notification permissions on your phone.

7.4. False Alarms

• Sensor Placement: Re-evaluate the placement of PIR motion detectors to avoid areas with direct sunlight, heat sources, or drafts that could cause false triggers. For anti-pet PIRs, ensure they are installed at the recommended height (2.2m) to avoid pets.
• Sensitivity: Some sensors may have adjustable sensitivity settings. Consult individual sensor manuals if available.
• Environmental Factors: Extreme temperature changes or strong electromagnetic interference can sometimes affect sensor performance.
