Overview
A front porch or apartment entry gets a wired video doorbell that records head to toe in a tall frame and talks with the visitor. Power comes over PoE or existing doorbell wiring, and footage goes to a microSD card, HomeKit or a NAS.
Aqara gives Apple households a doorbell that records into HomeKit Secure Video while still working with Alexa, Google and SmartThings, plus local storage with no cloud needed. Wired power is required, so homes without a doorbell circuit or PoE line face extra work, and HomeKit caps the resolution.
Who it's for
Apple users and smart home tinkerers with a wired doorbell or PoE run will use its local recording and wide platform support. Renters without doorbell wiring should look at a battery model instead, since no battery is listed here.
Pros and cons
- Works with HomeKit, Alexa, Google, SmartThings
- Local person detection without cloud
- Tall head-to-toe field of view
- Continuous recording to microSD
- Requires doorbell wiring or PoE
- MicroSD card not included
- HomeKit lowers maximum resolution
- HomeKit video needs iCloud+ and a hub
Performance notes
Image coverage comes from the tall wide-angle lens, which takes in packages at the doorstep and faces together. Infrared LEDs light the scene at night without a visible glow. Detection runs on the device itself, so person alerts and zone intrusion work without cloud processing, and continuous recording depends on a card being installed.
