I was browsing gearbest.com a couple of weeks back when I came across a preorder for the Xiaomi Video Doorbell. I always wanted to try one out, but the most interesting feature was the Face ID and the fact that it is integrated with MiHome (possible NodeRED compatibility?). I decided to make a purchase, the Xiaomi Video Doorbell has arrived so I thought I will talk about it more before I put it on the door.

Xiaomi Video Doorbell

Inside the box, you will find the Xiaomi Video Doorbell security screw driver, a couple of screws and a set of batteries (thank you very much). Other than that, even instructions are lacking. It’s not ideal since I’m expecting the product to talk to me in Chinese.

Fortunately, I had no issues connecting it to MiHome app. The doorbell was up and running in seconds. A very good start.

I will quickly go through some functions I notieced in the app:

Various triggers (motion sensing, button press, anti-tamper protection and knock on the door detection)

(motion sensing, button press, anti-tamper protection and knock on the door detection) Live View with Face ID (this is cool, more on that later)

(this is cool, more on that later) Stored video clips (free 1-year with 7 day log included)

(free 1-year with log included) intercom function (talk, listed and send pre-recorded messages)

(talk, listed and send pre-recorded messages) voice changer (yes, that’s a thing)

(yes, that’s a thing) autoresponder

Call me impressed. So what’s the catch? The Xiaomi Video Doorbell is Chinese and MiHome app has the best support with China server in terms of devices. It also by default speaks Chinese, which isn’t a big problem.

How does it work?

The Xiaomi Video Doorbell is battery powered (4 x AA) so it will spend most of it’s time sleeping. You cannot use the device as an IP camera. The live feed is only available when the device is triggered.

When triggered, the device will record a short video clip, and issue a notification (you can mute unwanted trigger) telling you what triggered the Xiaomi Video Doorbell. That information is stored in the timeline style log, video clips can be downloaded to local storage.

The camera quality is great. I’m yet to test the night vision, but so far I’m impressed with the picture resolution and the latency (works over 2.4GHz WiFi). During the live view you will be able to send a pre-defined voice message (“I’m coming!” or “Go away you unsolicited person”) and mask your voice with a voice changer – great option to hide the age of the person answering the call. Lastly, there is a panic alarm, which is loud enough to annoy the person at the door.

Face ID

The face ID is hidden in the experimental settings. Each clip with faces, can have an ID tag assigned to it. It’s technically possible to get the information who is approaching the doorbell on your mobile, before thy press the button! It’s impressive. I’m not sure if I feel impressed or offended for the app identifying me as:

“38 year old male (stranger)” MiHome App

Time will tell how accurate is the Face ID but I’m looking forward to exploring this further with NodeRED.

Other features

It’s recommended to use the Xiaomi Video Doorbell with a MiHome Hub. You need some sort of device (other than phone) to make the noise in your home. The doorbell can also detect knocking, so tech-shy postman should still trigger it.

MiHome makes it wasy to link various events (not just button presses) to MiHome devices in the automation tab. I already have the doorbell sound linked to it. Your options include controling lights, gadgets, etc.

I’m looking forward to automate this more.

Conclusion

I’m seriously impressed, especially that Xiaomi Video Doorbell is not an expensive gadget and you can get it for £50. The only negative thing that comes to my mind is the weather resistance (*I made a custom enclosure for it). The device looks watertight from the front, but not so much where the batteries go. It’s not a massive problem as my entrance is mostly shielded from rain, your situation may not be as good. Any questions? Feel free to comment in this Reddit thread.
