Doorbell cameras are transforming the way we look after our homes. Here is how they work and why they are worth checking out, from live video to motion alerts.

How a Doorbell Camera Actually Works

Fundamentally, a doorbell camera is a smart home device that takes the place of your ordinary doorbell. But instead of only ringing, it records live video and typically features things like motion detection, two-way audio and app integration.

When someone steps up to your front door, the camera either starts recording, or sends your phone a message, based on your settings. Then you can open an app on your phone and look to see who’s there — whether you’re home or not.

You can also speak to the visitor through a built-in microphone and speaker on most doorbell cameras. This can be incredibly useful for instructions for deliveries, surprise visitors, or even just discouraging potential intruders.

Some models capture footage locally to an SD card, while others save to the cloud. Many also connect with smart home hubs, so you can control all your devices from one dashboard.

Important Features to Consider in the Best Doorbell Camera

All doorbell camera systems are not created equal. If you’re in the market for one, there are a few features that can make a big difference:

HD video: This means 1080p resolution or better, and will provide clear images to help you identify faces and packages.
Infrared or low-light: A lot of visitors come in after dark, so if you want to get a good look at those antlers you might as well spring for one with infrared or low-light capability.
Wide viewing angle: The wider it is (say 160 degrees or above), the more of the doorway you see.
Active motion detection: Receive instant alerts and real-time video of anyone at your front door with motion-activated alerts.
Two-way audio: The convenience and security of being able to talk to a visitor even when you’re not home.

These essentials are often included in models such as the doorbell camera from trusted home security companies.

What Are the Advantages of a Doorbell Camera?

The most apparent advantage is seeing information in real time. Know who’s knocking at your door, even when you’re miles away. That’s a significant upgrade from peepholes and intercoms, which are standard in the industry.

But the benefits go deeper. Security camera on a doorbell can also help you prevent package theft by watching deliveries as they come in. You can also monitor activity logs that show who’s been at your door — and when — such as service people or children coming home, as well as those who rent out their property.

And, of course, they are convenient. Whether you’re in your garden, or at a distant office, you can now control access and communication with a few taps of your smartphone.

Do Doorbell Cameras Actually Deter Crime?

Yes indeed, in a number of ways. Although a doorbell camera can’t prevent your door from being physically forced open, it’s an important piece of the larger home security puzzle.

It’s your first visual defense — recording before someone even steps foot inside your house. Comes with two-way talk, so you can also scare off anyone with those features. Motion alerts tell you if someone’s lingering around your door.

Pair that doorbell camera with other smart security tools — indoor cameras or smart locks, for example — and it suggests a full-circle approach to protecting your home.

Its footage can also be beneficial for law enforcement or community watch reports if anything suspicious is going on or there is a theft.

Does Your Home Need a Doorbell Camera?

A doorbell camera is not just for those into tech, it’s for anyone seeking to have more knowledge, control and peace of mind whatsoever.

Whether you’re in a bustling city, a quiet suburb or even an apartment, a video doorbell is an easy and great way to make you feel a little more secure. Just make sure you select a model that accommodates your door setup and has all the features you want.

With relatively simple installation and instant payback. After you start using one, you wouldn’t imagine your entryway without them.
