Make your home a smart home with aosu wireless doorbell with camera. See a person from head to toe or a package on the ground with 166° view. Get a clearer picture with detailed 3K, 5.0-MP DWDR video ensuring you can see even in low light or bright conditions. It connects directly to Wi-Fi® without the clutter of extra gear - ideal for new home installation as well as retro fitting. The aosu doorbell is easy to install and is weather-resistant so you’ll always have a great camera view, year-round. Know who's there, even in the dark with night vision. Never miss a moment with the smart door sensor to see what triggered a motion event before it happened because the video doorbell captures video prior to every motion-triggered video recording so you don't miss out. Receive a video call to your phone to hear and speak to visitors at your door with clear, 2-way audio or respond with pre-recorded quick-reply messages when you are busy. Receive notifications for people, vehicles, and packages and take quicker action like sound the siren, call a friend, or dial emergency services. Ward off unwanted guests by triggering the siren automatically or manually from the aosu app. Pair with select Alexa®-enabled devices to enable announcements and 2-way talk for convenient in-home monitoring. And, you’ll enjoy a half year of surveillance from just 1 charge!
