aosu Video Doorbell R1 Ultra Review: 5MP and 60 Days of Storage With No Subscription
A 166 degree head-to-toe view through optical glass, triple-sensor detection, and a base station that stores two months of clips for free.
This is the doorbell that made aosu a name, and the reason is simple: it gives you a genuinely high-resolution camera and two months of recorded history without asking for a monthly fee. The 5MP sensor behind a seven-element glass lens with a 166 degree field of view in 4:3 shows a visitor head to toe and a package on the mat, the included aosuBase Mini holds 8GB with 60-day loop recording, and detection combines radar, PIR and AI to cut false alerts. It runs on battery for a wire-free install or wired for good. The weak points are inconsistent battery experiences, some human-detection misses, and a few reports of dead-on-arrival units.

Who is the aosu Video Doorbell R1 Ultra for?
It is aimed at people who want a premium-feeling doorbell without the recurring cost. The camera is 5MP behind a seven-piece optical glass lens, and the 166 degree field of view in a 4:3 vertical frame is specifically shaped so you can see a caller from head to toe as well as anything left on the ground. Storage is the differentiator: the aosuBase Mini included in the box holds 8GB and does 60-day loop recording, so real-time alerts, two-way audio, human detection and playback all work with no plan attached, with optional cloud subscriptions only for advanced AI and longer retention. Detection is a three-in-one system of radar, PIR infrared and AI human recognition with customizable zones. Power is flexible, either the rechargeable battery for a wire-free install or existing doorbell wiring, and it takes both 2.4GHz and 5GHz Wi-Fi, which is unusual in this category.
What buyers love
The no-subscription local storage is what buyers keep coming back to. One owner explicitly says they always wanted a video doorbell but never wanted another monthly fee, and another upgrading from an old intercom picked it specifically for local storage. Longevity reports are encouraging, with an owner at nearly a year describing it working flawlessly and setup as easy and straightforward, and another liking it enough to buy a second for a different door and add aosu solar cameras alongside. Buyers who have cycled through Eufy, Botslab and Lorex rate aosu's install as the cleanest of the group with strong 5MP resolution. Support also gets credit: an owner whose first unit had a charging fault describes the company being responsive and the replacement working properly.
What to know before you buy
Battery is the least consistent part of the experience. aosu rates it at around 90 days, but one owner reports the charge simply not lasting and notifications being weak, and another whose unit was hardwired throughout found it stopped charging after about two years. Detection also has a gap: a buyer who otherwise rates the camera quality highly calls human detection poor, which sits oddly against the triple-sensor marketing, and a second owner had a unit arrive with a damaged microphone and speaker and had to prove the fault before a return was authorised. There is one installation caveat worth flagging: an owner wiring it into a new-build cabin found it needed a resistor fitted after the low-voltage transformer to work correctly. On integrations, it covers Alexa and Google Assistant only, with no HomeKit, Matter, SmartThings or RTSP, and the more advanced AI detections such as package and familiar-face recognition sit behind the optional cloud plan.
Is the aosu Video Doorbell R1 Ultra worth it?
For most front doors, yes. Nothing else at this price pairs a 5MP head-to-toe camera with two months of free local recording, and the volume of positive owner feedback over multiple years suggests the core product is sound. Go in knowing the battery may not hit 90 days in a busy doorway, wire it in if you can, and check for the transformer resistor issue on a new install. If you need Apple Home, Matter or an RTSP stream, this is not the doorbell for you.
Frequently asked questions
Does the aosu Video Doorbell R1 Ultra need a subscription?
No. The included aosuBase Mini has 8GB of storage with 60-day loop recording, and real-time alerts, two-way audio, human detection and playback all work without a plan. Cloud subscriptions only add advanced AI detections and longer retention.
How long does the aosu doorbell battery last?
aosu rates it at about 90 days. Real-world reports vary a lot, with some owners satisfied and others finding it drains much faster, so if you have existing doorbell wiring it is worth using the wired option.
What is the field of view on the aosu R1 Ultra?
166 degrees diagonal, framed in 4:3 rather than widescreen. That vertical shape is deliberate, so you see a caller from head to toe and can also see packages left on the ground.
Does the aosu doorbell work on 5GHz Wi-Fi?
Yes. Unlike most video doorbells, which are 2.4GHz only, this one supports both 2.4GHz and 5GHz networks.
Does the aosu R1 Ultra work with Apple HomeKit?
No. It supports Amazon Alexa and Google Assistant only. There is no HomeKit, Matter, SmartThings or RTSP support, so it stays within the aosu app plus those two voice platforms.
Can the aosu doorbell be hardwired?
Yes, it supports both battery and wired power. One owner on a new build did find they needed a resistor fitted after the low-voltage transformer for it to operate correctly, so check that if you are wiring into a fresh installation.
