A smart smoke detector is a handy addition to any home, apartment, or office. These devices not only protect you with an alarm but can also alert you while you’re away. That’s because these devices will send a signal to the cloud so you can receive alerts on your smartphone.

Smart Smoke Detectors

For many years, people have been dealing with the high-pitched beeps from fire detectors. But now, with new smart smoke detectors, you can get voice alerts and smartphone notifications instead. We’ve compiled a list of the best smart smoke detectors for your home.

Smart Smoke Detectors Quick Facts

Fire and smoke detection sensors

When it comes to smoke alarms, there are two types to keep in mind: ionization and photoelectric. Ionization alarms react best to fast-burning fires, while photoelectric alarms will be better at telling you about smoldering fires. You should have both alarm types in your house. For example, the Nest Protect is designed with both types of alarms.

Carbon monoxide and other gas detection

You might not have a fire in your home, but it’s important to protect yourself against carbon monoxide. It can be deadly, even if you don’t see the smoke coming. For this reason, a good carbon monoxide detector should detect carbon monoxide and other harmful gas.

Hardwired vs. battery-powered

Hardwired alarms do not usually use batteries as they are powered by electricity in your home. The only time a hardwired alarm uses batteries is as a backup. They provide a steady and reliable alert, and if one goes off, all the rest will go off too. Standalone detectors need regular batteries and cannot signal each other in the event of an emergency, but are usually easier to mount. For instance, if you’re on a budget and want to save space, a standalone detector might be right for you.

Nest’s smoke detector can alert you to both carbon monoxide and smoke, and when it does, it will not only sound an alarm but also tell you in which room the alarm is coming from. The smoke detector will also emit a visual cue: a ring of light on the bottom of the alarm that changes color to let you know what is going on.

The Nest Protect comes in both wired and battery-powered versions. For peace of mind, it’s best to have more than just one Nest Protect in your home. When the alarm goes off on one Nest Protect, the others will sound an alert to tell you which location the fire is closest to.
