It doesn't look like the current gen Canary home security camera will receive official compatibility for HomeKit, however the next-gen Canary Plus will have official HomeKit support, and is expected in Autumn 2016.
Specs
Pros
Pro Captures clear video even in pitch black
The Canary has a viewing angle of 147 degrees, letting it see more than competing products. The 1080p resolution is crisp, and allows for digital zooming up to 3X. There are 12 infra-red LEDs that work as part of the night vision to keep recording even after the lights have gone out.
Pro Loud warning siren can scare away intruders
The Canary Security System is equipped with a siren which is rated at 90dB (similar to that of city traffic or a subway at 200ft). While not ridiculously loud, it should do the job to scare the heebie jeebies out of anybody not expecting it.
Pro Automatic enabling based on your phone's GPS location
The Canary can utilize your phone's GPS to turn on and off automatically depending on where you are (when you're at home it will enter private mode, but when you leave it will activate). If you live with others, all they need to do is install the app and it won't activate when they're home either.
Cons
Con Expensive subscription plan
The free plan is limited - your history will only go back 12 hours, with 5 available bookbarks and you can download 3 videos.
The $5/month ($49 annually) plan increases this to a 2 day history, 25 bookmarks, and unlimited downloads.
For $10/month ($99 annually) you get 7 day history, 100 bookmarks and still get unlimited downloads.
The most expensive plan at $30/month ($299 annually) gives you a 30 day timeline with unlimited bookmarks and downloads.
Con Requires a hack to properly work with Homekit
Out of the box, this product isn't Homekit compatible. However, you can make it work through a hack.
