The alarms are using Universal Smoke Sensing Technology, which relies on a microprocessor to quickly detect "fast flaming" fires, as well as those that smolder slowly. It's up to 87 percent faster than the current smoke alarm standards, the company says.

It might seem crazy to expect consumers to pay a premium for smoke detectors, which typically cost anywhere from $10 to $30. But Roost's smart functionality is genuinely useful, especially if you have a family to worry about. Its smart detectors are also cheaper than $99 Nest Protect (which is admittedly a lot more stylish).
