Video Quality: Daytime pictures are about as sharp and clear as we've seen, which means you can see most but not all of the details and subtle patterns in the scene. At nighttime, the video is very good: quite viewable, with a fair amount of brightness and clarity.
Data security: This model has very good security. It has many of the important protections for your recordings and personal data.
Data privacy: Aqara offers only a mediocre level of control and transparency over your data. They are not doing as good a job as others are with regard to collecting only necessary data, giving you control over its use, and limiting how your data is shared or sold.
Response time: This model sends its alerts to its app within 2.4 seconds on average, which is very quick, and helps you be very responsive to situations.
Smart features: It works with smart-home systems such as Amazon Alexa, Apple HomeKit, Apple Siri, Google Assistant, Samsung SmartThings. You'll need to install the Aqara Home app on your smartphone. Aqara claims this model has recognition algorithms that can detect people, sounds, vehicles, animals, and packages, as well as crying, alarm sounds, barking, coughing, and a lingering person. Aqara may offer additional features that require a subscription and/or a firmware update.
