In the age of the Internetofthings，nearly everything in your house is connected to a network.While you may be comfortable enough to use smart devices to manage your everyday tasks，will you be comfortable with them looking after your children as well？That's one question that can possibly arise with Google's latest patent—a “remote babysitter” that makes use of cameras and motion sensors(运动传感器)to track children at home.
According to the search giant's patent application，the proposed device aims to protect children in a home by disabling potential dangerous devices and by providing childprotection warnings.
The “smart babysitter” may use its sensors to determine if a child is left unattended in a room.According to the application，this will be done by scanning the room for persons with a threshold(门槛)．Video and sensors may be used to pick up persons below the threshold like crawling babies and children who are just learning to walk.When there is no person that meets the height of the threshold for a given amount of time，then the program will email the parents of the unattended child.
Moreover，“smart wall plugs” will also discover the occupancy in one room.Data will also be gathered to disable unused electrical outlets(插座)when a child comes into contact with them.They can also disable electronically controlled door handles in the event that a child gets close to them.
Added features that have been shown in the patent include blinking lights and audio warnings like “Your child is approaching an electrical outlet” or “Your child is alone for 10 minutes”．All these will be powered by Internetconnected motion detectors and cameras in order to track the child's movements，as well as smart devices around the home.
