In addition, the Nest Protect has sensors for carbon monoxide, heat, humidity and occupancy. In our lab, we tested the Nest Protect as with all smoke detectors by spraying an aerosol smoke detector tester spray from 5, 10 and 15 feet away, and timing how long it took each alarm to go off. At the 5 and 10 foot mark, the Nest Protect sounded after 18 seconds. At 15 feet, the alarm activated after 28 seconds. Moreover, it was the only device to pass all of our tests.

After we spent more than 40 hours testing a half dozen video doorbells, we think the best you can get is the Nest Hello Smart Wi Fi Video Doorbell. It has the highest video quality, can recognize individual faces—and can announce them to you, too. The best video doorbell under $100 is the Ring Video Doorbell. Although its resolution is just 720p—lower than the other video doorbells—but video was clear enough to see who was at the door, and Ring's app has a lot of excellent features. Trying to decide which Ring video doorbell to get?We've put together a comparison of the Ring, Ring Video Doorbell 2, Ring Pro, and the Ring Door View Cam.
