A French company has designed a camerathat recognizes faces and tells people if a stranger has entered their home.Many homes now have security camerasthat tell owners if someone has entered.But the cameras do not know if the person is a family member,friend, delivery person or a criminal.But a new camera made by a company named Netatmohas facial recognition software that can tell parents at workthat their children have returned from school,or that a package has been delivered to their home.It can also tell them if a stranger has entered their home.Janina Mattausch is a product marketing manager for Netatmo."Current security cameras are not that smart.So, they can tell you if something is moving but they don't necessarily know if it's a human being or, ah,if it's your kids -- they don't know the difference, so they will alert you all the time."When family members enter a home,the smart camera "recognizes" them and sends information to the owner's smartphone.The owner can choose to see the video then or later.But if an unknown person enters a home,the camera will send the owner an alertthat will cause an alarm to sound on the owner's smartphone.That is what happened recently to a smart home camera owner named Damien.He lives in Paris."On a Friday I was at work, attending a big monthly meetingwhen my phone vibrated. At first I told myself ‘Oh, it must be a wrong alert, maybe I have to do some adjustments'-- but the notification on my phone was telling me that there was a movement in my flatand also a face that the app did not recognize."He watched the video and was very surprised by what he saw."I saw a person I did not know with his shoes on,which is totally forbidden in my apartment. I was watching it live on video.So I felt totally frozen, stupefied.I asked a colleague to take me back home as fast as possible and I called the police on the way."Damien showed the video of the intruder to the police.The criminal was found later that day.He was sentenced to nine months in jail.
