FAQs (Product)
Q1: Is the Xiaomi Smart Doorbell 4 weatherproof for use outdoors? A1: While smart doorbells like the Xiaomi Doorbell 4 are designed for outdoor use and can handle typical weather, the exact IP rating (e.g., IP65) can vary by version. It is generally advised to install it in a sheltered location, such as under a porch or eave, to ensure long-term reliability against heavy rainfall.
Q2: How does the Dual Camera system benefit me? A2: The Dual Camera system typically includes a main camera for the visitor's face and a second camera pointed towards the ground. This ensures you can see people from head to toe and, crucially, monitor any packages or deliveries left directly below the doorbell that a single camera might miss.
Q3: Do I need to buy an indoor chime separately? A3: No, the Xiaomi Smart Doorbell 4 usually comes with a dedicated indoor chime/receiver module in the package, which is plugged into an electrical outlet inside your home.
Q4: Does this doorbell require a subscription for cloud storage? A4: The Xiaomi Smart Doorbell 4 typically offers a free tier of cloud storage, such as 3-day rolling cloud storage for event videos. If you require longer video history or advanced features like extended face recognition, a paid cloud subscription service would be necessary.
Q5: Can I hardwire the Xiaomi Smart Doorbell 4? A5: Some premium versions of the Xiaomi Smart Doorbell (like the Smart Doorbell 3S) support both battery and hardwired power supply (8-24VAC), but the standard Doorbell 4 is primarily a battery-powered device. Please check the specific packaging details for the exact model you purchase.
