Aosu R1 Ultra Offers Subscription-Free Local Storage but Has Minor Flaws, TechRadar Says

According to TechRadar, the R1 Ultra's main appeal is that buyers do not need a subscription to see useful footage. Clips go to the included AosuBase Mini, a plug-in indoor box with 8GB of storage that acts as a Wi-Fi bridge, indoor chime and storage device. It keeps a rolling 60 days of footage. Alerts, live view, two-way talk, custom detection zones and full playback are available without paying extra. An optional cloud plan, AosuProtect+, is advertised in the UK at £9.99 a month or £122.99 a year, currently discounted to £3.49 and £39.99; TechRadar noted the annual price is simply the monthly rate multiplied by twelve.

TechRadar said detection is a strength. Instead of relying only on a passive infrared sensor, the doorbell layers radar and AI human recognition to judge distance and intent, distinguishing approaching from passing and lingering from walking through. The two-way talk screen includes a Tone button that can answer the door as 'uncle' or 'clown'. The uncle setting artificially deepens voices, transitioning women and children to something resembling a man to deter would-be intruders, while the clown setting raises and distorts the voice to mask identity. Other features include an anti-tamper alert with local footage and battery or wired installation.

The review listed several drawbacks. Night vision is infrared only. Recharging requires unclipping the entire doorbell, and a full charge takes six hours. Quick replies cannot be edited or customized, the base station must remain plugged in indefinitely, and there is no Matter or HomeKit support.

TechRadar also said the spec sheet slightly oversells the product. The claimed 5MP UHD resolution is not true UHD: the sensor is 2560 x 1920, or 4.9 megapixels in a 4:3 frame, which is sharp and a step up from 2K doorbells at this price but not 3,840 x 2,160. The asserted 60% improvement over standard 2K only holds if the comparison is Aosu's own 3MP doorbell, and an earlier version of the identical claim on the identical camera said 40%. The stated 166-degree field of view is a corner-to-corner measurement; in reality, TechRadar said, it is 133 degrees horizontal by 103 degrees vertical, shot in a shallow 4:3 aspect ratio with no head-to-toe image tricks.

With realistic use, the battery should last six months between charges, but because the cell is not quick-release, users must remove the whole unit and go without it while it charges. At its usual discounted price, especially around £100, TechRadar judged the value case strong because the base station is included rather than a £50 upsell and because 60 days of local recording would cost a subscription almost anywhere else. The review gave value a score of 4 out of 5. TechRadar's verdict was that if buyers purchase the R1 Ultra for what it does rather than what it claims, it is a capable smart security investment.
