Smart doorbell modern

The modern smart doorbell goes beyond sound: it offers real-time video, motion detection, and integration with virtual assistants.

About this subject

The smart doorbell is a home security device that replaces the traditional doorbell, integrating a camera, microphone, and speaker. Connected via Wi-Fi, it allows homeowners to see and talk to visitors through a smartphone app from anywhere. This market segment has grown rapidly since the launch of the Ring Video Doorbell in 2014, with the global market estimated at US$2.3 billion in 2023 and projected to reach US$5.4 billion by 2029, according to Mordor Intelligence.

Modern models include motion sensors with customizable zones, infrared night vision, and cloud recording (often with a subscription). Integration with ecosystems like Amazon Alexa, Google Assistant, and Apple HomeKit enables routines: for instance, when motion is detected, the porch light turns on and the indoor alarm disarms. Some devices offer facial recognition and send specific alerts for known faces versus strangers.

A key concern is privacy. Internet-connected cameras raise worries about unauthorized access to video data. Manufacturers like Ring have been criticized for storing recordings indefinitely and for partnerships with law enforcement in the US. To mitigate risks, users are advised to enable two-factor authentication and review app permissions.

In Brazil, adoption grows with the rise of home automation. Brands like Intelbras, Positivo, and Multilaser offer models priced between R$200 and R$800, usually with local storage via microSD card. Installation is straightforward but requires existing doorbell wiring of 8-24V AC for continuous power. Battery-powered models last 2 to 6 months depending on usage.

Frequently Asked Questions

How does a smart doorbell work?

It replaces the standard doorbell with a unit that has a camera and microphone, connected to the internet. When pressed or motion is detected, it sends a notification to the homeowner’s smartphone, allowing them to see and talk to the visitor via the app.

Is a smart doorbell safe to use?

Yes, as long as the user sets strong passwords, enables two-factor authentication, and keeps firmware updated. Choosing models that allow local storage instead of only cloud storage also enhances privacy.

Does it require professional installation?

Not necessarily. Most models are designed for DIY installation, attaching to the wall and connecting to existing doorbell wires. For battery-powered models, just mount the bracket and attach the unit.
