aosu Video Doorbell R1 Ultra vs Ring Battery Doorbell 4K Pro

The aosu Video Doorbell R1 Ultra is the better overall pick here, winning on price and on free local storage, plus Google Home support the Ring Battery Doorbell 4K Pro does not offer. The Ring Battery Doorbell 4K Pro pulls ahead on alerts, with vehicle detection, automatic Quick Replies and a sharper 4K sensor, so it stays competitive for buyers already inside the Ring or Alexa ecosystem.

Storage and power flexibility. The aosu Video Doorbell R1 Ultra pairs with an included aosuBase Mini station that records locally for two months with no subscription, and it can run wired or on battery. The Ring Battery Doorbell 4K Pro has no local storage or microSD slot, and keeps every saved clip behind a Ring Protect subscription, though its 4K sensor is the sharper of the two.

Only the Ring Battery Doorbell 4K Pro requires one to save anything. It has no internal storage or microSD slot, so a Ring Protect subscription is the only way to keep a clip, and without a plan you only get live view. The aosu Video Doorbell R1 Ultra records to its included aosuBase Mini station for free on a 60-day loop, and only its more advanced AI detections need an optional cloud plan.

The aosu Video Doorbell R1 Ultra works with Alexa and Google Home. The Ring Battery Doorbell 4K Pro works with Alexa and Home Assistant, through the community ring-mqtt integration, instead of Google Home. Neither supports Apple HomeKit, Samsung SmartThings or Matter.

Buyers who want to record and review video without paying a monthly subscription, who want the lower price of the two, or who already run Google Home in their smart home setup.

Buyers already inside the Ring or Alexa ecosystem who want the sharpest available image, Ring's fuller subscription-based alert set including vehicle detection, and automatic Quick Replies.
