Engineer Arkaits Garro created a system from a mini computer Raspberry Pi and a camera. On the computer, he installed a motion motion detection system motionEyeOS and connected the cloud service for image recognition Amazon Rekognition. The camera captures the motion and takes a picture. Then the system compares the photograph of the cat named Bobis with the previous photos. If it's Bobis, and not another cat or, for example, a squirrel, Garro gets a notification on his phone with the message "Open the door!".
