What is the Nest Hello?

It’s surprising that it’s taken so long for a major competitor to launch a video doorbell to challenge the Ring. The wait has well been worth it: the Nest Hello builds on the Ring Video Doorbell’s features, adding additional security and convenience to your front door.

Portrait-mode answering, continuous video recording, and the ability to answer your door from your Google Home all make the Nest Hello a robust, intelligent and flexible method by which to protect your front door. By protect, I don’t just mean for people walking up to your front door; the fact that the Nest Hello can record permanently also means that this model is a quality security camera that lets you see what’s going on outside your front door.

Nest Hello – Design and build

  • Smart, slim and discreet design
  • Fiddly wired-only design; professional installation is available to customers

Nest kit – such as the Nest Cam IQ Outdoor – has always impressed in the ‘looks’ department, and the Nest Hello is no different. The sleek black lozenge-shaped case will be right at home on the outside of your house. I found it smart enough to make it obvious that the Nest Hello is a doorbell and should, therefore, be pressed by guests; plain enough that it doesn’t ruin the exterior of your home.

At 117 x 43 x 26mm, the Nest Hello is considerably slimmer than the Ring Video Doorbell 2. This is largely because the Nest Hello is a wired-only product, so there’s no bulky battery to accommodate in the external casing. This is something that Ring has managed to avoid in its Door View peephole camera by fitting the battery to the inside of the door, and only leaving the camera on display.

The Nest Hello’s slimmer body makes the device a little easier to fit in some locations. I live in a Victorian house with narrow door frames, which didn’t easily accommodate the Ring Video Doorbell 2, and I ended up having to use the wedge adaptor, pointing the camera away from the garden path leading up to the door. The Nest Hello was positioned far easier, fitting onto the door frame, covering the full pathway to my front door.

In the box  you’ll find a 15-degree wedge to angle the doorbell, so you can get the field of view you need to cover your entry-way if you have a different layout to me.

Since the Nest Hello is wired-only, installation isn’t as convenient as it is with the Ring Video Doorbell 2. For starters, you’ll need a transformer, and an existing one may not do the job; Nest requires a 16-to-24V AC transformer and many UK models are 12V. I had to have my transformer upgraded to get the Nest Hello installed; a problem that I didn’t have when wiring in the Ring Video Doorbell 2. You’ll need an internal chime, too.

Although a competent DIYer will be able to tackle the installation, a professional install may be the route worth taking or many. This will set you back £100 and will include connecting the doorbell and getting it working through the app. Nest can provide installation at the time of purchase, calling in an approved installer from across its network.

Note that you may need a replacement transformer and chime; the installation service doesn’t cover running new cabling, so expect to pay more if you don’t have a wired doorbell.

Nest Hello – Features

  • Works well on the Nest app
  • However, we had a hitch trying to connect it to the Nest Protect hub
  • Excellent camera quality, and easy-to-use software

The Nest Hello is managed through the Nest app, which is also home to other products in the range, such as the Nest Cam IQ and Nest Thermostat. If you already have some Nest kit, a single place for everything is super-convenient.

Hooking up the Nest Hello to your home network is fairly straightforward. In my case, Nest wanted to use my Nest Protect to help the camera join my home network. This should have required a simple tap of the Nest Protect’s main button, but the procedure failed the first time.

Annoyingly, Nest doesn’t provide an alternative installation method. In the end, I removed the Nest Protect from the wall (it’s in an outside office) and moved it to the front door, where the Nest Hello connected and paired to my home network. It would be far easier if Nest let you enter a wireless network manually should its installation fail.

The Nest Hello has built-in 802.11ac Wi-Fi, but UK regulations are such that only the 2.4GHz band is supported. Make sure, then, that you have a strong wireless connection at the front door.

Once the camera is connected, the Nest Hello can be monitored and controlled just like any other Nest camera. Video is shot at a resolution of 1600 x 1200, and presented in portrait rather than landscape. Combined with the 160-degree lens, the video format is a good choice, since it means you capture a person’s entire body as they approach your front door.

As with other Nest cameras, you can set a schedule for when the camera is active, or have it turn on or off based on your location. You shouldn’t use location tracking and scheduling together, since it can have unpredictable results – the camera might turn off when you’re out.

However, with this type of product, it makes far more sense to leave the camera on permanently.

A press of the button on the pad outside will make your indoor chime ring, and you’ll receive a pop-up notification on your phone (and Apple Watch, if you have one). Answer it to have a conversation, just as you’d expect.

If you’re in a rush, there are three pre-defined speech options, which are read out by the Google Assistant through the doorbell’s speaker: “You can leave it”, “We’ll be right with you”, “We can’t answer the door”. All three are a little terse, but could be handy if you’re otherwise occupied, such as in a meeting at work.

Nest uses a Chime connector, which sits between the doorbell and your indoor chime. It’s a neat addition, as it means that you can turn off your internal chime permanently if you don’t want it to ring.

Using the Quiet Time feature in the app, you can also temporarily disable the chime for 30, 60 or 90 minutes. It’s a shame there’s no option to schedule Quiet Time for longer periods, such as overnight.

Nest Hello – Performance and Nest Aware

  • The chime works as well as any doorbell
  • Smart notifications take a few moments to come through, particularly when you’re out and about
  • The microphone and speaker are of excellent quality
  • A subscription to Nest Aware isn’t so expensive and will help you get the most out of the product
  • Facial recognition tech is good and keeps getting better

The internal chime ring is instant and as quick as using a traditional doorbell. Smartphone notifications can take up to 30 seconds to come through to your phone, and answering takes a few seconds more while the app connects. This is quicker than with the Ring Video Doorbell, which takes a while to wake up and connect to your wireless network, particularly on battery mode.

If you’re out and about, the quality of your mobile signal has an important part to play and I’ve had the very occasional situation where the Nest app would try and connect to the Nest Hello, but time out and cause the doorbell to reboot. That’s a little frustrating, but in most cases I’ve been able to answer the doorbell quickly before the person ringing has moved on.

The high-quality microphone and external speaker make it easy and clear to have a chat with whoever is at your front door. Even better, since the video is in portrait mode, you can hold your phone normally to have a chat. Ring requires you to turn your phone into landscape mode, which is trickier; plus, the phone isn’t as comfortable or as secure to hold in this position.

By default, the Nest Hello can recognise people, which you can use to configure motion alerts: you can toggle notifications for general motion or people. That’s a neat way to keep track of who goes up to your front door, but who may not ring the bell. Via the app, you can view thumbnails of previous activity, including motion and ring events.

As with other Nest cameras, the Nest Hello becomes far better when you add a Nest Aware subscription. The most important addition is 24/7 video recording. With this turned on, you can scroll back through your video history and watch everything that went on; there’s no chance of missing a crucial event because the camera hadn’t been triggered to record.

The Nest App is fantastic at handling this, with its timeline view letting you scroll through everything effortlessly, highlighting events (motion and rings) so that they’re easy to find. Alternatively, the event view lets you just jump straight to an event, with thumbnails making it easy to find the one that you want. Nest is the gold standard for video history; no other security camera, let alone doorbell, comes close to the power on offer here.

The downside of continuous recording is the bandwidth that the system will use. According to Nest, a camera set to Low quality will typically use 50GB of data a month; on Medium it’s 150GB and on High it’s 300GB. You’ll definitely want an unlimited connection with a decent upload speed to use this feature, particularly if you want to set the video to high.

There’s also an option to listen for and alert you to loud noises. With a less sophisticated microphone, the Nest Hello doesn’t have the ‘Person talking’ and ‘Dog barking’ alerts of some of the other cameras. I don’t think that this is a big issue, as noise detection can often result in lots of false positives, with constant alerts when a camera thinks that it’s heard something important.

Nest Aware also adds a few additional features. Zones let you configure the part of the image you want to monitor, cutting down on false alerts by, say, ignoring a neighbour walking past. For each zone, you can toggle person and motion alerts individually. Nest also lets you digitally zoom and lock the zoom level, which can be a good way of cropping out a neighbour’s garden: under current UK law, you can record the street, but you should take into account neighbour’s privacy by not overtly recording their comings and goings.

Nest Hello Zones

Facial recognition is also available. Any faces recognised by other cameras (the Nest Cam IQ or Nest Cam Outdoor IQ) are carried over and automatically recognised by Nest Hello. For new faces, you can tell the app which people you recognise, and which you don’t. This personalises the notifications you receive, with Nest telling you if there’s someone familiar or unfamiliar at the door. It’s a shame you can’t control alerts based on whether someone was recognised or not.

Facial recognition is really powerful, and the system gets better over time; the more it sees the same people. Mistakes can be made, however, and Nest can sometimes make two entries for the same person. These can be merged to improve detection in the future.

Nest Aware used to be very expensive, but the new entry-level subscription is just £4 a month (or £40 for a year) for five days of video history. That’s excellent value, particularly when you consider that  Nest Aware’s camera or doorbell’s cloud storage offering is far better than that of rivals.

Nest Hello – Video quality

  • Very good picture quality overall, though it can struggle with fast-moving subjects

Nest uses HDR to deliver better-quality footage without blown-out or shadow areas obscuring details – and it works well. The footage during the day is brilliantly exposed across the entire picture.

Due to compression, faster-moving video loses a bit of detail, but you get a sharp image when someone is stood in front of your door waiting for you to answer. There’s very little noise in the image, and it’s easy to recognise individuals. Certainly, compared to the competition, the Nest Hello is up there.

At night, the camera uses its IR LEDs. These were powerful enough to light up my entire front garden. Some detail is lost and the image becomes a bit noisier, but the same qualities shine through and you get a detailed image of anyone waiting outside of your home.

Nest Hello – Google Assistant, Amazon Alexa, IFTTT and more

  • Compatible with Google Assistant, Amazon Alexa, and IFTTT
  • Integration is strongest with Google, however you still can’t answer the doorbell via smart speaker

Nest Hello works with Google Assistant notifications. When the doorbell is pressed, your Google Home (or other Assistant-enabled devices) will announce that there’s someone at the door, so you know without having to be close to your phone or within earshot of your doorbell. If the camera has recognised someone, the notification tells you that there’s someone you recognise at the front door. It’s a shame that it won’t tell you who’s at the front door, though.

Control of Notifications can be toggled per device using the Google Assistant app (not the Google Home app) on your phone (iOS and Android). You can also cast the video stream to a Chromecast, if you just want to see what’s going on.

If you have a smart display, such as the Google Home Hub or Lenovo Smart Display 10″, there’s another trick: the screen shows you a live feed from the Nest Hello, alongside the voice notification, so you can see who’s at the door. Even better, you can now answer directly from the device. You may find that the feature’s not working for you and that when you tap answer you don’t get the video stream. The answer to this problem is to unlink your Nest account from the Google Home app and then add it again.

Once I’d done this, tapping the Talk button let me answer the front door and then have a conversation with whoever’s on the other side. I found that this was far quicker than having to pull out my phone, tap the notification and load the app to do the same thing, particularly as I have a Home Hub on my desk. Call quality will largely come down to the quality of the smart display that you’re using: the Google Home Hub does a great job and was louder than using my iPhone.

If you don’t want to talk to the person ringing your door, you can tap the Responses button and use one of the canned responses (‘You can leave it at the door’ and so on) instead. Again, doing this using a smart display is faster than using your phone.

It’s a shame that you can’t answer your doorbell through a smart speaker, such as the Google Home. Although this device will tell you that there’s someone at the door, it can’t open a two-way channel for a chat. It would make so much sense if you could say something like, ‘OK Google, answer the front door’.

Alexa support is available, although this is limited to viewing the camera feed on a video-enabled device, such as the Amazon Echo Show or Fire TV. Currently, there’s no option for announcements or answering a ring.

An IFTTT channel has Triggers only, so you can control other devices when your Nest Hello has a sound or motion event (or both). For better automation, there’s Works with Nest, which has some automated rules. For example, when you’ve been away for more than 24 hours, motion can make your Philips Hue lights turn on automatically to trick someone into thinking you’re at home.

Why buy the Nest Hello?

Without a battery, the Nest Hello isn’t quite as easy or as convenient to install as the Ring Video Doorbell 2, which can be installed practically anywhere. But that’s the only minor downside, as the fully wired Nest Hello has so many more advantages over its competition.

Swifter performance, Google Home notifications and smart display answering, plus, with Nest Aware, continuous video recording and facial recognition make the Nest Hello the best video doorbell available. It’s also a great security camera in its own right, too For the ultimate protection of your front door, this is the model to buy.
