4. Setup Guide
4.1 Initial Charging
Before first use, fully charge the doorbell using the provided Type-C charging cable. The charging port is located on the device. Ensure the doorbell switch (located on the back) is turned on during charging and operation.
4.2 App Installation
The doorbell operates with the Tuya or Smart Life application. These apps are compatible with Android 4.3 and above.
- Scan the QR code provided in the physical manual (not included here) or search for "Tuya" or "Smart Life" in your smartphone's app store (Google Play Store for Android, Apple App Store for iOS).
- Download and install the application.
- Register a new account or log in if you already have one.
4.3 Device Pairing
- Open the Smart Life or Tuya APP.
- Tap on "Add Device" or the "+" icon in the top right corner.
- Select "Smart Doorbell" from the list of available devices.
- Follow the on-screen instructions within the APP to connect the doorbell to your 2.4GHz WiFi network. This typically involves putting the doorbell into pairing mode (refer to APP instructions for specific button presses) and entering your WiFi credentials.
- Once successfully paired, the doorbell will appear in your device list within the APP.
4.4 Installation
The doorbell can be installed using the provided back sticker or by screw drilling for a more secure attachment.
- Adhesive Installation: Clean the desired surface thoroughly. Peel off the protective film from the back sticker and firmly press the doorbell onto the surface. Ensure it is level and secure.
- Screw Installation: For enhanced security, use the provided screws and anchors. Mark the drilling points using the back panel as a template. Drill holes, insert anchors, and then secure the back panel with screws. Finally, attach the doorbell unit to the secured back panel. This method provides a very tight connection, making it difficult to remove without tools.

Frequent awakening of the camera (e.g., constant live viewing or high motion detection sensitivity) can lead to faster power consumption.
6.2 Cleaning
Periodically wipe the doorbell's lens and body with a soft, damp cloth to remove dust and dirt. Do not use harsh chemicals or abrasive cleaners, as these may damage the device.
