Aosu Video Doorbell Ultra Review

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

The Aosu Video Doorbell Ultra was launched a couple of years ago, and it is one of the best-reviewed video doorbells on Amazon. Still, it is a brand that I overlooked due to the sheer volume of random Chinese brands on Amazon.

I have used the video doorbell for the p[past couple of weeks, and I have come away surprised at how good it is.

Set Up and Aosu App Settings

The IOSO video doorbell is easy to set up.

  1. Set Up Home Base: Plug in the chime, open the IOS app, add the device, scan the QR code, and connect to Wi-Fi.
  2. Sync Doorbell: Press the sync button on the chime and doorbell. The app will generate a QR code for the doorbell to scan.
  3. Mounting: Screw the mount into place and snap the doorbell in. Use the push pin to remove the doorbell if needed.

Subscription Fees

You can use this camera without a subscription and have access to most of the features free of charge. This includes advanced object detection and human detection, but it does not include facial detection.

There are various subscription options including:

  • Basic Plan for 1 device: £5.58 PCM or £55.80 annually, and this gives 14 days of recording
  • Face AI for 1 device: £5.58 PCM or £55.80 annually

Motion Detection & Facial Detection

This camera supports motion detection, human detection and facial detection but doesn’t seem to support cars, animals or packages.

Human detection works without a subscription, and I think that is all most people really need.

This then uses three different technologies for detection:

  • Radar Motion Detection: Scans for distance and movement
  • PIR Motion Detection: Scans for body heat
  • Human Motion Detection: Scans for human shape

Then, if you subscribe to the Face AI, you can upload a photo of someone, and it will use this to identify the person.

The Face AI is good, but not as good as the Eufy cameras that utilise the HomeBase 3. The Eufy cameras allow you to select strangers’ faces and add them to the recognition, and it will also ask to confirm similar faces to improve accuracy.

Overall, I found human detection to be good, and in my opinion, it is really all you need for video doorbells in most scenarios.

Day Time Footage Quality

Footage captured during the day time is typically good. The video starts off very dark for a fraction of a second but brightens up to reveal plenty of detail about who is at the door.

The video has a 4:3 aspect ratio and a resolution of 2560×1920. It claims to have a 166-degree field of view with head-to-toe coverage. That isn’t the case from my experience, the vertical field of view is nowhere near as good as Arlo or the dual camera design of the Video Doorbell E340, but I found that the coverage was still good enough for my needs.

Night Time Footage Quality

Footage shot at night is in black and white, like most video doorbells. The footage is about average, it is perfectly usable but you do lose a lot of detail with black and white.

Battery Life

I have only used the doorbell for a couple of weeks. I had low expectations of the battery life as most brands struggle with this, and lesser-known brands tend to perform below average.

However, the battery has been very impressive. It appears to have lost less than 1% point per day, and I expect it should last comfortably over 3 months. That is under the quoted battery life, but that’s true for most brands I have tried and so far this has performed just as well as some of the best options I have reviewed (which are typically from Eufy).

Price and Alternative Options

The Aosu Video Doorbell Ultra is available directly from for £105, and the lower-spec Video Doorbell Pro is £73.

It is also available from Amazon and is listed at £150. At the time of writing it was discounted to £120 with a £10 voucher also available.

As for alternative options, you have:

Ring Video Doorbell (2nd Gen) which only costs £100 but requires a subscription.

Blink Video Doorbell is only £60 and doesn’t require a subscription, but it lacks a chime and has so-so reviews.

Tapo 2K 5MP Smart Wireless Security Camera Doorbell might be the best alternative, price at £120. This is also a 5MP doorbell, and it uses a starlight sensor, so it should perform better in low light, and it has free local storage. It has smart AI object detection but lacks facial recognition.

The eufy Security Video Doorbell Wireless S210 is available for around £110, it has 16GB of local storage and no subscription needed. It has advanced AI object detection but no facial detection, and from my experience, the battery is superb.


I have been pleasantly surprised with the Aosu Video Doorbell Ultra.

It is not the best video doorbell on the market, but I think it is one of the best options at the £100 price point.

There is no need for a subscription, making it much more appealing as an affordable video doorbell than Arlo, Ring and Google options.

Video quality and motion detection have been good. Facial detection is walled off as a subscription. It is a great feature, but I don’t think it is worth the price.

Finally, the battery life is superb, being one of the best doorbells I have tried for battery life.
