Google's Nest Doorbell bell is now offered with a rechargeable battery, can recognize faces and design is brilliant in certain aspects.But it is expensive and does not always fill its promises.

WE love

We see from the installation of the Nest Doorbell that Google engineers thought of the small details.This new model includes a rechargeable battery that will allow you to screw it on any door or surface, without worrying about spinning.Its announced autonomy is between one and six months, depending on your use.

So we start by loading it by inserting a USB-C cable for a few hours and configuring it with the Google Home application.A video shows us how to install its metallic support first, and a nice surprise awaits us: the box contains a second angle support which allows you to center the vision of the camera if you install the doorbell on one side of the door.A good idea.

Once the doorbell is fully loaded, you are mooring it on the support on the door.To remove it later to recharge it, no need to unscrew as we have to do with the ring ring, the rival proposed by Amazon.With the Nest doorbell, just insert a special key to the top of the device to get it.Again, beautiful find.

From there, each time the doorbell detects a presence, it sends a notification on your mobile devices, telephone or tablet.It tells you if it is a person, a package, an animal or a vehicle, and you have free access to videos of the last three hours.If someone rings, all the Google Home devices of the house will make a small chime and a voice will announce that "ring indicates that someone has come".

You can see live what the doorbell detects in your mobile device, from the Home application, or by kindly asking your Nest Hub with a screen.You can also, by pressing the microphone icon, speak to the person at the door.

The video resolution is good, from 960 on 1280 pixels for 30 images per second, with a camera oriented vertically to film visitors from top to bottom.

If you subscribe to Nest Aware for $ 8 per month or $ 80 per year, with a free 30 -day trial, the video events of the last 30 days are available.Above all, you get the familiar faces recognition function.For each event, you are invited to identify the person with their name.

And it works pretty well, let's say twice out of three.The doorbell will have difficulty recognizing a person who leaves the house, who wears a mask or any headgear.Same limit for the detection of packages: they must be clearly visible and identifiable, which only happened to us once in two.

WE love moins

We may have defined a smaller area of camera detection, the door is many, many false alerts.It only takes a passer -by on the sidewalk or Halloween decorations that bolt in the wind to trigger a notification.We quickly made these silent notifications in front of the avalanche of alerts from the first days.

The battery's autonomy leaves something to be desired.In 12 days of testing, with a mild fall temperature, we consumed half of the battery.We dare not imagine what will happen during the cold weather.

At $ 239.99, to which ideally added the subscription to Nest Aware, this gadget is expensive.

If you want to hear an advertisement indicating that someone has come, you must have a Google smart speaker.Otherwise, you will only have notifications on your mobile device.

One buys ?

Overall, we found the Nest Doorbell a little less useful than the ring that we had tested.Its incessant notifications and the uninstated configuration in the Google Home application are probably to blame.And the autonomy of his battery is clearly insufficient.

But it must be recognized that the recognition of faces and packages, even imperfect, installation possibilities and the ease of withdrawing it, as well as free video recordings of the last three hours are arguments to the advantage of the Nest Doorbell.A user of the Google ecosystem, which already has its intelligent speaker, will probably be better served with this device.
