Powered by Xfinity Internet, this buzzer is simple to watch, disarm, and prepare for the child’s. Customers receive notifications of their smartphone, while streaming their TV on the Internet through Comcast’s X1 or Flex services. Open the mobile app to see your visitor from the head up and access the two-way radio. There’s also the option to assign particular areas of interest. So you receive motion notification only when someone is in front of the gate, before entering the driveway or through the yard. It is also integrated with Comcast’s xFi Advanced Security suite. Like its competitors Ring or Nest, the Xfinity-based offering boasts an HD camera with 4:3 aspect ratio and an intercom, making it easy to greet visitors without leaving the couch or giving the delivery a call to the cab. The Xfinity Home Doorbell is available for professional use for Xfinity Home Pro Protection and Pro Protection Plus customers in a total of twelve dollars. It will go on sale to Xfinity Home Self Protection customers in the early next year.
