"How We TestedEase of UseOur testing team built a custom apparatus designed specifically to analyze each smoke alarm’s detection capabilities. It was placed in the center of a room measuring 25. 33 x 18. 83 feet. We mounted and hardwired each of the detectors to the apparatus and noted how long it took to install each one using the included manufacturer instructions. After connecting each alarm to a Wi Fi network, we installed its associated mobile app on a smartphone. We evaluated how easy each app is to use and tested how long it takes for notifications to arrive on your mobile device when there is an emergency. We also assessed how well each device connects to third party smart home automation systems. We contacted each company, when possible, to assess how helpful its representatives are when
resolving potential technical problems. Detection EfficiencyOur detection efficiency testing is for comparison purposes only and was not designed to replace industry standard safety certifications carried by each unit we reviewed. Perhaps the most important thing we learned from our testing is
that smoke detectors have a limited range, which is one of the reasons modern building codes require a unit in every bedroom as well as in areas adjacent to bedrooms.

Once you teach it the
names of frequent visitors, the companion app available for both Android and iOS will start to name them in the push notifications. The Nest Hello gets big points for including a snapshot from the camera with each notification, so you can get a glimpse of what's happening without having to open the app. The snapshots are extra handy when facial recognition is wrong — which didn't happen often, to be fair. First, the app asked me to identify my family and close friends multiple times from photos the Hello took. You can do this for anyone who comes to your door. I tagged my husband four times, for example, and my son six times. In the Nest app's Familiar Faces gallery, you can tap Select,
choose all the instances of the same person, and tap Merge to combine them. After that, it worked pretty smoothly, but it did misidentify my husband one night as my son's best friend, a 6 year old African American boy who wears glasses. My husband is much taller, a lot older and Caucasian, and does not wear glasses. I also wish the Nest Hello used facial recognition a little better. There's no way to exclude certain individuals from triggering a notification when they're recognized, for example, and I don't need the app to tell me that it's me who just arrived home.
