Which is the best video doorbell camera?
The Arlo Video Doorbell comes with added features you won’t get with other devices, such as night vision and a wide, 180-degree field of view.
Arlo
The Arlo Video Doorbell is our pick for the overall best video doorbell camera. It has a wide field of view (180 degrees), built-in siren and night vision. This camera will meet and exceed expectations for most households, making it stand above the competition.
As shown by Arlo’s model, not all video doorbell cameras are created equal — design, installation cost, video quality and video storage subscriptions for each doorbell cam can vary immensely. Some also have features that may give you pause on ethical grounds.
If you aren’t sure where to begin in your search for a smart video doorbell, take a look below, where we’ve rounded up our favorite models. We’ve also offered a few general pointers on finding the best security camera device for you. If you’re looking for the best doorbell camera, chances are it’s among those we’ve tested. We update this list periodically.

How we test video doorbells
Testing to determine the best video doorbell is similar to testing any other home security camera.
Installation and setup process
First, a reviewer will download the corresponding app and create an account. While a lot of products include tutorial booklets in the box with your purchase, a good app includes detailed steps on the installation process, as well as how to connect to your Wi-Fi network and actually get the smart device up and running. It’s your one-stop shop for taking your doorbell setup from start to finish.
We make sure the doorbell is installed based on the manufacturer’s specifications — either a hardwired doorbell, or a battery- or solar-powered one.
Here are two wireless video doorbells, Wyze and Blink, that we installed to the CNET Smart Home for testing.

Additional features and settings
As soon as it’s connected and we’re able to view the live video feed, we check the settings. We make sure features like motion detection, two-way or activity zones are enabled (they aren’t always turned on by default) to get a complete sense of what it’s like to use the product — and to see how well the device actually works as a replacement to a regular, nonsmart doorbell.
To test motion zones, we first determine the motion zone, then move around it to see when we get an alert and when we don’t. The aim is to discover how precise those zones really are. For two-way talk, we’ll have a conversation with a partner on the porch via the doorbell to listen for clarity and latency.
While testing, we always check how seamlessly the video doorbell camera integrates with third-party smart home voice assistants, like Alexa, as well as how usable the brand’s app is for installation and monitoring.

App integration
Like smart locks and home security cameras, many top-notch video doorbells will allow the camera to be integrated with voice assistants like Amazon Alexa or Google Assistant. We download the respective apps, connect the video doorbell and see the ease (or hassle) of using voice commands to control the doorbell camera, plus how easily the doorbell cam integrates into the wider ecosystem of smart devices.

What to consider before buying a doorbell camera
Does it work with smart home platforms? If so, do the smart features work well together? Nowadays a smart home device is expected to work with at least one major smart home platform. Amazon Alexa, Google Assistant and Apple HomeKit are the main ones you need to look for.
How’s the latency? If your smart doorbell camera takes a long time to send a push notification after someone rings your doorbell, then you risk missing your visitor completely. You also need to be sure you’re getting notifications when something sets off the motion detector, as you can set the motion sensor of most video doorbells to notify you of activity happening near your door, even if no one rings the buzzer. If you have latency problems, start with your Wi-Fi connection. If it isn’t strong where the doorbell is installed, you might consider moving it (or, more easily, getting a Wi-Fi range extender).
But it could also be the way the software works.
How’s the live view? Doorbells are often exposed to direct sunlight, but many others are installed under porches, near shady trees and in all sorts of other settings. It’s important that the camera has night vision and can handle any of these scenarios so you don’t get stuck with a nonfunctioning product that can’t see faces under a porch.
How’s the two-way audio? If the doorbell’s microphone and speaker don’t work well, you’re going to have a tough time communicating with whoever’s there. We tested this out multiple times to see how the doorbell’s audio sounds over my phone.

Best Ring Doorbell of 2023

- Ring doorbell FAQs
If you are on the fence regarding whether to invest in a video doorbell, let me tell you right away that they are the perfect way to improve your home security.
Video doorbells allow you to see exactly who’s at your door, and with the ability to record, they become even more useful. The best Ring doorbells also let you interact with whoever is at the door, even when you’re not home.
If you’re considering upgrading your home security with a video doorbell, Ring has probably crossed your mind. Amazon’s home security brand has become increasingly popular and has a reputation as one of the best video doorbells on the market. While Google Nest buzzers and Arlo doorbell cams are great alternatives, many people looking to buy a video doorbell still opt for the industry’s biggest brand.
Ring has an extensive selection of video doorbells that meet the needs of a wide variety of homes. Are you looking for a wireless or hardwired option? Do you want to prioritize buying something affordable, or do you want the latest devices with all of the bells and whistles? Ring has a complicated history with privacy and police partnerships, so you might also be wondering if some devices are better at protecting your privacy than others? Yes, shopping for video doorbells can give rise to a lot of questions.
We’ve got all the answers for you. Let’s take a look at Ring’s most popular recent devices — the Ring 4, the Doorbell Pro 2, the Video Doorbell (2020) and the Ring Video Doorbell (Wired) — and help you break down the best Ring doorbell options.
Best Ring doorbells
How to choose Ring video doorbells
When you’re looking for a video doorbell, the most important question isn’t “Which one is best?” so much as “Which one is best for me?” All of Ring’s video doorbells perform well — and all of them come from the same company, with the same troubling history of facilitating video sharing with police. Not all of them will be ideal for you.
If you’re curious about trying out a video doorbell for the first time, mostly for basic features like live monitoring, two-way talk and so on, a starter device like the Ring Video Doorbell (the 2020 model, or its Wired version) should do what you need.
On the other hand, if you really want to see what a smart video doorbell can accomplish in 2023, the Video Doorbell Pro 2 is pretty unbeatable in terms of smart doorbell features — and especially with that option to use end-to-end video encryption.
That leaves the Video Doorbell 4 as the middle child, with a bit for both kinds of people, but not necessarily the best value or features around.
If you’re interested in video doorbells, don’t forget to take a look at the video doorbell competition, too.

How we test Ring video doorbells
Testing to determine the best of the best in video doorbells is similar to how we test any other home security camera. For this article, I started by downloading the Ring app. I recommend starting with the app rather than sifting through the tutorial booklets that ship with the hardware, because a good app includes detailed steps on the installation process, as well as how to connect the doorbell to your Wi-Fi network. The app will also be where you can check your notifications, alerts and settings, making it your one-stop shop for all things video doorbell-related.
After installing the video doorbells based on the manufacturer’s specifications, it was time to test the specs.
Each video doorbell, despite all being Ring products, has slightly different features, so I took the time to test each unique feature to determine which was best. As soon as the Ring video doorbells were connected and I could view the live video feed, I checked their settings. I enabled features like motion detection, package alerts and bird’s-eye-view to get a sense of how well each feature performed.
Watch this: Ring 4 or Nest Doorbell Battery? Find the better fit for your porch
After hours of testing, I gave the highest rating (7.5) to the Ring Video Doorbell Pro 2. While it’s not the best value on the market, the advanced specs — a super-wide field of view, a 1:1 aspect ratio, 1536p resolution and all the basics you’d want your smart buzzer to have — make it a great choice for a high-end video doorbell.
Though rated lower than the Pro 2 at a 7.4, the Ring Video Doorbell 4 is my recommendation for best standard Ring doorbell.
If you’re looking for a doorbell that’s a fair value and packed with nifty features, but just doesn’t send package alerts, then this is the best choice.
Finally, we gave the Ring Video Doorbell (2020) our lowest score (7.2) because it’s certainly an improvement over the original Ring Video Doorbell, but the built-in battery that needs to be removed to charge is a bit of a hassle. While it’s not our very favorite, it’s a decent buzzer with solid features at a fair value.

Connecting Home base 2 to Wi-Fi
This article will help you switch your home base from an Ethernet cable connection to a Wi-Fi connection.
Theoretically, the home base can be located 15 meters from the WI-Fi router. The actual range will vary depending on a number of factors such as wall thickness, obstacles inside the home, and the location of the router.
Before you do
1. If the range of the home base and camera is within acceptable limits and the signal is strong, it is recommended to use a standard Ethernet cable connection.
2. If your home base and camera range are out of range, you can set your home base to connect via Wi-Fi. Of course, the corresponding network transmission will become less stable and the real-time stream may have more delays.
How to do
1. During the setup process, the home base must connect to the router using an Ethernet cable.
2. After setting up the home base, you can switch to Wi-Fi connection in the device tab > Select Home base > Home base settings > General > Wi-Fi connection . This step in the application also applies to other versions of home base.

KP top 11 rating
Doorbells are installed in modern apartments and houses, but now they are far from what they used to be. Even in such devices modern technologies are used. They allow not only to know in advance what kind of guests have arrived to you, but also, for example, to listen to pleasant music instead of a standard call.
And if you are not at home, then with the help of such devices you can monitor the situation.
KP figured out what makes the best smart doorbells in 2023. There are enough manufacturers of such goods on the Russian market, but the choice must be approached wisely so as not to regret later that it broke down after six months.

Pros and cons Easy to operate. A small number of functions How to choose a smart door bellKomsomolskaya Pravda told Komsomolskaya Pravda about the features of smart bells and tips on choosing the best model programmer Danil Kosyagin . Frequently Asked QuestionsWhat details should I pay attention to first?Wireless signal transmission sensors There are bells with a mechanical principle of operation, they hardly belong to the category of “smart”. Electronic devices are equipped with sensors and microcircuits capable of wireless signal transmission. More expensive models even have a video communication system. Thanks to the installation of special applications, you will be able to see what is happening at your home from anywhere in the world. Weatherproof Look out for features such as dust and moisture resistance. Protection must be reliable so that the device does not deteriorate. Volume The volume level is different – both for ordinary doorbells and for “smart” ones. The best option is models where the volume can be adjusted. In modern times, this option is available to almost everyone. The loudest devices are those with a sound level of 80 to 100 dB. Power Power is required not only for the receiver, but also for the button in the bells where it is available. The speaker, as a rule, can be connected to the electrical network of a house or apartment. True, for installation, drilling of the walls may be required. Functions In smart calls, this is the most important thing. Pros and cons of wired and wireless smart bell connection Wired calls are cheap. This is generally a reliable and easy to use design. At the same time, holes will have to be made in the wall and door to install a wired bell. Wireless calls reach communication through a radio signal. There are no “cosmetic” consequences when installing them for your home. They have more features, they look modern. But these devices are more expensive. In addition, the signal may be lost when passing through doors and walls. How to set up a smart bell with artificial intelligence?

The detection of motion sensors, night vision system, automatic saving of frames – all this increases the safety of the user and his family. So, modern models allow you to determine exactly who is approaching your door – to “distinguish” a person from a passing car. There are devices that allow you to change your voice – this can also scare off intruders. More expensive calls have a face recognition system.
