Excellent smart device equipped with optional video recording and facial recognition functions can also be used as a doorbell Google’s new Nest Hello is a video doorbell designed to achieve intelligence through continuous recording, face and object recognition. Hello is a direct replacement for wired doorbells, works with existing ringtones and requires constant power, making it one of the high-end options for smart doorbells. The need for power limits where you can place it, unlike some more flexible options, such as the battery-powered Ring Video Doorbell 2, but can achieve more powerful functions.
Features
Hello is a modern doorbell with a simple appearance, with a large button with a luminous blue ring on it and a camera on it. It is about twice as large as a traditional doorbell and is screwed directly into the wall. When someone approaches the door, the light ring pulses around the doorbell button, enticing them to push the doorbell button. The doorbell will trigger the connected ringtone when pressed, but it will also send a notification to your phone, and can alert any of your GoogleHome smart speakers. Then you can choose to ignore the caller, press the button in the app to read out the automatic message (the options are: "You can leave it"; "We will be there", and, suddenly, "No one can come to the door "Or" talk to the caller via the phone via the doorbell.
installation
Hello may be an easy setting or a task, depending on whether you have wired the doorbell and the voltage of the transformer. If you have a wired doorbell with the correct voltage transformer, then switching it to Nest Hello is as easy as unscrewing the old one, disconnect the two wires, drill two holes in the wall, and screw the back plate into place, Reconnect the wire to the back of Hello and cut it in place. In the Nest app on Android or iPhone, you need about 5 to 10 minutes to complete the setup routine. This is the easy way. Unfortunately, Hello needs a transformer that outputs a voltage of 16 to 24V AC, which is not commonly used in British households, which means you may need a new transformer and an electrician to install it for you. Then there are houses without wired doorbells, like mine, not only need to install a transformer, but also a bell and all wiring-this process may take several hours and requires a qualified electrician to complete the work. Google can sell Hello separately or through a professional installation, but the installation only covers replacing the existing wired doorbell with Nest Hello and replacing the transformer as needed. If you don't have a wired doorbell, you need to organize it separately if you want an electrician to install all the necessary wiring.
use it
After installing Hello, using it is very simple. Just like the Nest Thermostat, if you have never really used any "smart" functions, then the Hello function is like a very fashionable doorbell. It’s not that the existing wired doorbells that it replaces are worse. Smart home devices are not always the case. When someone clicks the button, it will trigger a ringtone and alert your phone, as well as any Google Assistant you may have. If you are at home most of the time, you might just look at the character in the notice and answer the door yourself. But if you don't know who it is-someone is trying to sell you a new religion or political party-you can talk to them directly through the Nest app on your phone. By tapping the notification, you can answer the real-time feed from the door via the button and talk to the caller, use the button to play a pre-recorded message or ignore the caller's option. As long as you have an internet connection on your phone, it can work at home or away from home. You can also access the live stream from the camera at any time via the Nest app or via a compatible smart display (such as Amazon's Echo Show).
Cloud options
The rest of the non-doorbell functions will change depending on whether you have purchased Nest Aware. If there is no monthly cloud storage, you can choose to enable various basic alarms, such as when the camera detects a person, any other movement, or hears sound. Each notification is accompanied by a snapshot image taken from the camera, which is saved in the Nest app as a timeline of the previous event, but I found that the image of the event that just happened does not always appear in the timeline immediately. With a Nest Aware subscription for £4 per month, things get more advanced. Hello continuously streams videos to the cloud and records 24 hours a day. Not only can you view event snapshots, you can also view everything in between, making it an excellent security camera. Even at night, the video quality is very good, and shooting in high dynamic range (HDR), if your camera is facing the sun, this will make a real difference. The video is recorded in a 4:3 ratio with a relatively wide angle. Like all these cameras, when they are away from the door, it is still difficult to make a name tag on the caller, but you can clearly make the face and logo. Streaming videos are processed in real time by Google's AI, enabling a series of smarter tools. For example, you can get notifications similar to people, actions, and sounds as before, but they will be slightly enhanced, significantly eliminating more false positives, and allowing you to narrow the notifications to certain areas within the camera's field of view. The notification sent to the phone also contains a GIF, which shows a small animated snapshot of the person or object, making it easier for you to see if you need to perform any action on the notification. Clicking on the notification will directly go to the full video of the related event, and then you can save and share as needed. If you want to pay more attention to the set point, you can also zoom in on a specific area.
face recognition
Facial recognition is an important difference between Hello and competitors such as Amazon's Ring. It is supported by Google's cloud, so it requires a Nest Aware subscription. The idea is that when people approach the front door, the system will find faces and then allow you to tag them with names. The next time the person arrives at the door and presses the button, the notification you receive on your phone will show their name, and Google’s smart speaker can also announce their name. In practice, facial recognition is not as magical or scary as you think. It recognizes most people as multiple people, but allows you to manually merge them into one and delete images of inappropriate people. Initially, this meant that you knew me as three separate people-one "Sam" with sunglasses and two other "Sams", until I merged them into one "Sam" to rule them. For less frequent visitors, sometimes it cannot be recognized as a previously marked face. Although all video and facial data can only be accessed through your Nest account, there are also privacy issues for constant recording and facial recognition. You also did not associate faces with accounts or similar things, but it is important that you at least explain all this to your neighbors.
opinion
The Nest app will provide you with complete installation instructions, even if you have an electrician install the doorbell for you, you cannot skip these instructions. tedious.
The hyperlapse effect of the video scrolling all day is very beautiful, looking at the sun streaks in the sky
I have received too many notifications and people who have not subscribed to Nest Aware have passed, which means I have to close them
The shadow of a person walking is recognized as a person, even if the person is actually not in your sports zone, it will trigger an alarm
Hello is weatherproof, but the back panel cannot fit the wall completely, so if it is exposed to heavy rain or similar places, water will enter behind it
You need a strong wifi signal for the doorbell and an unlimited broadband connection for Nest Aware video recording
You can silence the ringer for 30 minutes to 3 hours, but you cannot schedule it to stay quiet overnight or similar-you can manually turn it on or off in the app
price
The Nest Hello is priced at 229 pounds separately and 329 pounds for professional installation. The Nest Aware subscription costs £4 per month (£40 per year) for 5 days of video history, £8 per month (£80 per year) for 10 days of video history or £24 per month (£240 per year) for 30 Days of video history.
to sum up
Nest Hello is an excellent smart doorbell, still very suitable as an ordinary doorbell. If you rarely use smart bits, you can work without additional subscriptions. When you do want to use smart features, a Nest Aware subscription is almost certainly a necessity, at least another £4 per month add-on product. You can get great value for money, get constant video for seven days or more from the front door, making it an excellent security camera, as well as smarter and more practical alarms and other features. With some work, facial recognition should be useful for ordinary guests, and it's much smaller than you expect. The biggest problem of Hello is the strict requirements for wiring and power supply. This may be an obstacle, you only need to clear it once, but it will definitely increase the cost and difficulty of adapting to it in the first place. Hello is an excellent, high-end, feature-rich smart video doorbell option that can see the front part of your house. Before the game, this was not a very good league.
