The Aqara Video Doorbell isn’t my first smart video doorbell, however, it is my first one from this brand. The doorbell can be setup wirelessly to run on disposable batteries or wired to existing doorbell wiring; just note that your doorbell transformer needs to output 8-24V power. For installation and mounting, you’ll receive screws, wall anchors, and a 20° wedge if you need to horizontally angle the doorbell away from a corner wall. The kit also includes an indoor chime speaker, which acts as a WiFi hub, and USB-C cable to power it. The chime accepts a microSD card up to 512GB (not included) for local storage of videos and photos captured by the doorbell and does not require a subscription.
Setup is simple and straightforward with the Aqara Home app, and you’ll connect the chime unit directly to a 2.4 GHZ WiFi network which in turn will transmit data to and from the video doorbell; note that 5 GHz networks are not supported. The camera is secured to the backplate using a spring-loaded security screw, which is a clever way to ensure that you don’t drop or lose it. Once you slide the housing up and away from it, you can load 6 AA batteries inside (included). The unit comes pre-fitted with double-sided adhesive tape or optionally you can mount the camera doorbell permanently with the screws and anchors. If you wish to wire the doorbell, a punch-out window in the mounting plate can be removed, so you can attach the wires to the screw terminals on the back of the camera unit.
In the app, you can view a live feed from the video doorbell, manually capture recordings and stills, review recorded video footage and photos, and change the device’s settings. When the doorbell button is pressed, the indoor chime will sound (volume is adjustable up to 95 dB), and a LED ring around the button will illuminate indicating that the camera is recording; however, this light can be disabled in the settings. It automatically captures a short video clip of the event and sends push notifications to your app. You can also set the camera to record other events like loitering (general motion detection) and device tampering, as well as sound an alarm if the unit is removed from the backplate.
The camera captures a wide-angle, horizontal, 162° FOV image in 1080p quality and has automatic IR night vision when it’s dark out. In general, I found the video, image, and sound quality to be quite good. It has decent contrast and color and the recordings are clear, though by default there is a fisheye effect that distorts the image at the edges. Enabling lens correction squares the image so it looks more natural, which I preferred. However, be aware that switching between the two modes often can affect the device’s ability to recognize faces properly. Nighttime footage appears in black and white and some details are lost or fuzzy which makes it harder for the facial recognition to be as accurate. The other thing is since the video is oriented horizontally, you can't see the ground close to the camera, so if a package is left in that area, you won’t see it.
One smart feature you can enable is the AI facial recognition of frequent visitors. After capturing a collection of images, you can manage the facial data and tag them with names and trigger custom events when those individuals are detected on the camera, for example, playing a custom ringtone (up to 5 MP3s). Amazingly, all the AI facial recognition is performed in the chime unit itself and not on the cloud, so it’ll still work even without internet access. However, other advanced AI recognition like packages and animals were not available.
You can interact with folks in front of the camera by using the intercom feature in the app and while doing so, mask your voice with 3 different sounding filters: uncle, robot, and clown, which I thought was interesting. You can also adjust the camera’s motion sensitivity, define up to 3 privacy/occlusion zones, and enable timestamps on your footage. Just note that the privacy areas will be masked in the recordings and motion in these areas will not trigger events.
If you’ve inserted an SD card, by default the files saved to it are set to loop recording and will overwrite the oldest footage when the card is full. You can also have the files automatically sync/offload to network attached storage (NAS), like a computer on the same network, so that you’ll have access to more storage capacity for a longer video history, retaining up to 1 year of footage. However, an SD card is actually not required as the unit includes 7 days of free cloud storage without a subscription. Recorded events appear on a timeline in the app and you can color code/highlight different types of events so that you can find and review them quickly.
Continuous 24/7 recording is available as an option, which would store about 3 days worth of continuous recordings on a 32GB card, though it is only available when the unit is wired as to not quickly deplete the batteries, which can last 4 months depending on frequency of usage and operating temperatures. When wired, the installed batteries act as backup power if your power goes out.
The doorbell also has a number of compatible third-party integrations including Apple and Google Home, Alexa, and IFTTT allowing you to use the doorbell in custom automations with your other IoT devices, for example, having the video feed pop up automatically on a connected screen like Echo Show or Google Home Hub when the doorbell is pressed. Aqara also plans to add Matter integration as some point in the future through a firmware update.
The responsiveness between the doorbell and app was very good, and there is very minimal lag between camera detection and notifications/automations. Not only does this allow you to respond to doorbell presses right away, it makes communicating via the intercom way more pleasant as you’ll be able to see and hear the camera’s live feed in nearly real-time. I also liked that you can link other devices to it, for example Aqara's smart locks, so that you can unlock it right from the video monitor screen.
Overall, the Aqara G4 is the most fully featured video doorbell that I’ve tried to date, and I really appreciate the free cloud storage, unlimited 24/7 local recording, integrated facial recognition, and multiple compatible smart home integrations. With both wired and wireless options, anyone can install this doorbell, and combining its WiFi hub with an indoor chime is super convenient. The video and audio quality are already pretty good, but if a 2K or 4K version becomes available, I wouldn’t hesitate to trade up.
