0. $20, a dual sensor, battery powered smoke detector that earns positive feedback overall. It's been tested by Consumer Reports, and earns the top rating for detecting both smoldering fires and flaming ones, though not a recommendation presumably because it cannot be interconnected with other alarms. User reviews are positive, including a 4. 6 star rating at Home Depot, and recommendations from 98 percent of the nearly 100 owners that leave reviews. The ionization/photoelectric sensor smoke alarms above use standard batteries. However, they are inappropriate for those who live in a state or city that requires that battery operated smoke detectors be powered by sealed 10 year batteries. In that case, we suggest the
First Alert SA3210 Est. $50. It's very similar to the First Alert SA320CN save for the power source a sealed 10 year lithium battery that complies with regulations in those areas that require them. It's not been professionally reviewed, but the handful of user reviews we spotted
scattered on sites across the internet have largely been positive thus far.

believe that Nest Protect is the best of the group. It has outstanding detection capabilities and innovative alerts that let you know exactly what threat your home is facing and how to proceed. It’s intuitive to install and its high compatibility with third party products is a huge selling point as well. The only gripe we have is the relatively short warranty. The smoke sensor in the Nest Protect is different than any other smoke alarm we've looked at. The unit uses a split spectrum sensor, a special type of photoelectric sensor, which is designed to detect both smoky and flaming fires. The Nest Protect also has a built in a carbon monoxide sensor and will sound an alarm if it detects dangerous levels of the invisible,
odorless gas which can be lethal if you breathe it for too long. To help cut down on false alarms from steam and burnt toast, the Nest Protect also uses humidity and heat sensors. We tested the detection capabilities of each smoke detector in our comparison by spraying test smoke from an aerosol can directly at each one from 5, 10 and 15 feet away. When we tested the 5 and 10 foot mark, the Nest Protect sounded its alarm after 18 seconds.

For example, the iOS app has had the ability to adjust the motion sensor for weeks and it still hasn't made it to Android. I couldn't even activate it on my phone Moto X Pure 2015, I had to use a Galaxy S7 to sync it. While we are on motion sensitivity, out of the box the motion sensor is way too sensitive. There website says if someone lingers by the door for 10 seconds before sending you a push notification. But as soon as we were stepping out of the door it would go off.
Both our original and replacement unit had this issue. Also, the unit was picking up cars driving by on a road 50 feet away
from our house or changes in lighting shadows moving in the distance. After the first day of receiving 6 notifications in under an hour, we had to turn off one of the advertised features. Luckily, a few weeks later they added the ability to adjust the sensitivity and I just so happened to have an iPhone in a drawer, and I was able to use the iOS app to put it on low. Now we don't get any notifications from the motion sensor. Now that I think about it, I am actually concerned if it is working at all on low.
