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.
Ranked in these QuestionsQuestion Ranking
Pro Air quality sensors can help provide a more comfortable atmosphere
There are sensors which help determine the quality of the air, including: temperature, humidity, and particles in the air. While it can't do anything about these itself, it is a useful tool for monitoring.
Pro Great microphone clarity helps determine what is happening
The microphone is great, and captures crystal clear audio. This is extremely beneficial if there is motion detected, but then the subject moves out of the vision of the camera, as you can still somewhat tell whats going on.
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.
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.
Con Lacks a speaker
While there is a microphone to listen to sounds, there is no speaker and thus this system lacks the ability to hold a conversation with the person on the other side.
Con Must sit on a flat surface
This system will need a table or stand to sit on - there isn't an included wall or ceiling mount. You perhaps could fashion your own, however remember to mount it upright as the camera doesn't rotate.
Con Lots of false alarms
The motion detection is very sensitive - so sensitive that it only takes shadows moving or branches swaying in the wind to trick it into sending a false alarm. In the future Canary is going to add a sensitivity slider, however this hasn't been implemented yet.
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 No local storage
All of the recordings are stored directly on the cloud, and there is no local storage available.
