Setup and Installation
1. Charging the Devices
Before initial use, fully charge both the doorbell camera and the indoor monitor. The doorbell camera features an upgraded 7,000mAh rechargeable lithium battery, providing approximately 60-90 days of operation on a full charge, depending on usage. The touchscreen monitor has a built-in 5,000mAh battery, offering up to 6-8 hours of constant use.

2. Doorbell Placement
Select an optimal location for the doorbell camera. It is recommended to install the doorbell at a height that allows for a clear view of visitors. Avoid installing the doorbell on metal surfaces, as metal can significantly impact wireless signal strength and range.

3. Wireless Connection
The system connects wirelessly via Wi-Fi and a 915MHz signal, eliminating the need for complex wiring. The doorbell and monitor are typically pre-paired. If pairing is required, refer to the on-screen instructions on the monitor or the Tuya App.
