I LOVE my Canary. I constantly am trying to find new ways to make my little city apartment "smarter" and safer, and Canary totally nailed it. Their app is seamless and while there may not be a really obvious "panic" button, it's really easy to make the Canary sound an alarm (which is deafening... I tried it once as an experiment to the horror of my entire building). Also, the little "home health" features built in made me love it even more. Canary takes hourly little reports on temperature and air quality and makes beautiful little graphs, making my data-obsessed heart swell with joy. #1 home security product currently on the market, IMO.
