While Canary's security cameras can notify you when they detect something moving in your home, they can't differentiate between an intruder and your pet Fluffy doing zoomies. Once their new feature rolls out, though, you won't have to get 20 notifications in an hour if you don't want to. The company has announced that it's rolling out Person Detection to all Canary and Canary Flex cameras in the near future -- for free. It relies on machine learning to figure out whether your camera is seeing a human being, so the system can send you specific person alerts.
