aosu is a home security brand built around subscription-free video, selling battery and wired doorbell cameras, indoor and outdoor cameras and multi-camera kits. Its doorbells record locally to built-in storage or to a bundled base station rather than requiring a cloud plan, and pair 2K to 5K sensors with head-to-toe fields of view aimed at seeing packages on the doorstep. Devices are set up in the aosu app and work with Amazon Alexa and Google Assistant.
