What makes us different:

No Monthly Fee: When you purchase some doorbell brand, you may have to pay an additional subscription fee of more than 50 dollars per year. The longer you use it, the more you pay. But the aosu doorbell has 8 gigabytes of built-in memory, so no subscription is required.

5 Megapixel Resolution: Ensures you get high-quality, crisp images that show more detail without blurring (especially if you use digital zoom to blow up your videos).

Triple Motion Detection: Other doorbells on the market have only one passive infrared (PIR) sensor for object detection. We use both a radar sensor and a PIR sensor plus AI body detection technology, combining the advantages of heat and sound wave sensing to reduce false alarms by 95%.

5g/2.4g WiFi for Easy Connectivity: Follow the steps on the app or get our local US phone service (found in the package or user manual) for one-on-one help to complete your connection step-by-step.

Battery/Wired Options: Built-in rechargeable battery and 58% lower consumption for low-power wireless connections, ensuring 180 days of use on 1 charge, or connect to existing wiring for continuous power.

Lifetime Premium Service: Please feel free to reach us with any questions about the product (1. "Login Amazon" → "Your Account" → "Your orders" → "Ask Product Question"; 2. aosu app live online support; 3. Get our local US phone service) and we will find the best solution for you.
