In some implementations, the user interface 410 also includes one or more input devices 414, including user interface components that facilitate user input such as a keyboard, a mouse, a voice command input unit or microphone, a touch screen display, a touch sensitive input pad, a gesture capturing camera, a doorbell button or other input buttons or controls. Furthermore, some smart devices 204 use a microphone and voice recognition or a camera and gesture recognition to supplement or replace the keyboard. In some implementations, the smart device 204 includes one or more image/video capture devices 418 e. g. , cameras, video cameras, scanners, photo sensor units. The radios 440 enable one or more radio communication networks in the smart home environments, and allow a smart device 204 to communicate with other devices. In some implementations, the radios 440 are capable of data communications using any of a variety of custom or standard wireless protocols e. g. , IEEE 802. 15. 4, Wi Fi, ZigBee, 6LoWPAN, Thread, Z Wave, Bluetooth Smart, ISA100.
