5. Setup & Installation
The ZUIDID Video Doorbell Viewer is designed for easy installation with minimal parts. Please follow these steps carefully:
5.1. Pre-Installation Checks
- Door Thickness: Ensure your door thickness is between 40mm and 115mm.
- Peephole Diameter: Ensure your door's peephole diameter is between 14mm and 22mm.
5.2. Installation Steps
- Remove the existing peephole from your door.
- Insert the outdoor unit through the peephole from the outside of the door. Ensure the cable passes through the door.
- From the inside, connect the outdoor unit's cable to the indoor unit.
- Mount the hanging board on the inside of the door, aligning it with the outdoor unit.
- Secure the indoor unit to the hanging board using the provided fixing screws.
- Ensure the indoor unit is firmly attached and the outdoor unit is flush with the door surface.


5.3. App Connection
- Download the Tuya Smart app from your smartphone's app store (Android/iOS).
- Open the app and create an account or log in.
- On the indoor unit, press the button at the bottom of the screen for 5 seconds until you hear a voice prompt indicating pairing mode.
- In the Tuya app, tap 'Add Device' and select 'Smart Doorbell (Wi-Fi)' or similar camera/lock category.
- Follow the on-screen instructions to connect the device to your 2.4Ghz WiFi network. You may need to scan a QR code displayed on your phone with the doorbell camera.
- Once connected, the device will appear in your Tuya app, allowing remote monitoring and control.
6. Operating Instructions
6.1. Real-time Monitoring
- Indoor Unit: The 4.3-inch LCD screen automatically displays the outdoor view when the doorbell is pressed or motion is detected.
- Tuya App: Open the Tuya Smart app on your smartphone to view the live feed from the camera anytime, anywhere.
6.2. Two-Way Intercom
- When a visitor presses the doorbell, the indoor unit will ring and display the outdoor view. A video call request will also be sent to your smartphone via the Tuya app.
- Answer the call on your smartphone to speak with the visitor. The voice communication is clear.
6.3. PIR Motion Detection
- The PIR sensor detects continuous motion in front of the camera (typically 3-5 seconds of movement).
- Upon detection, an alarm message is sent to your mobile phone, and the outdoor situation is recorded in real-time.
- You can adjust the sensitivity of the PIR function within the Tuya app.
- The app allows you to give language warnings to suspicious individuals outdoors.

6.4. Night Vision
- The camera is equipped with infrared detection. It automatically switches to night vision mode in low-light conditions or at night.
- This ensures clear monitoring of the outdoor environment even in complete darkness, with an effective distance of about 3 meters.

7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the indoor and outdoor units. Avoid using abrasive cleaners or solvents.
- Battery Charging: The device is powered by a built-in 5000mAh lithium-ion battery. When the battery level drops below 5%, the Tuya app will send a low battery reminder. Recharge the device using the provided micro USB cable and a DC5V 1A power adapter.
- Software Updates: Regularly check the Tuya Smart app for any available firmware updates for your device to ensure optimal performance and security.
- Environmental Conditions: Ensure the outdoor unit is not exposed to extreme weather conditions beyond its operating temperature range (-20℃ to 55℃).
8. Troubleshooting
- Device not linking to APP when battery is low: This is expected behavior. The device will not link to the app when the battery power is less than 5%. Recharge the battery fully.
- PIR motion detection delay: A slight delay of a few seconds may occur due to network caching. This is normal. You can adjust the sensitivity settings in the Tuya app.
- Startup delay: There may be a delay of a few seconds when starting up the device. This is a normal phenomenon designed to protect the electronic components.
- Cannot connect to WiFi: Ensure your WiFi network is 2.4Ghz. The device does not support 5Ghz WiFi. Check your WiFi password and signal strength.
- No image or poor image quality: Check the camera lens for obstructions or dirt. Ensure the outdoor unit is properly installed and aligned. For night vision, ensure no strong light sources are directly facing the camera.
- Bell volume adjustment: The bell volume can be adjusted through the settings within the Tuya Smart app.
9. User Tips
- Always measure your door thickness and peephole diameter before purchasing to ensure compatibility.
- Download the Tuya Smart app for full functionality and remote control.
- Adjust the PIR motion detection sensitivity in the app to suit your environment and avoid false alarms.
- If you do not use an SD card, video recordings will occupy your phone's memory.
- Remember that intercom with visitors is primarily handled through the mobile phone app, not directly via the indoor monitor.
