g. , when available, when purchased, or at routine intervals. In some implementations, the network
interface 160 includes a conventional network device e. g. , a router, and the smart home environment 100 of FIG. 1 includes a hub device 180 that is
communicatively coupled to the networks 162 directly or via the network interface 160. The hub device 180 is further communicatively coupled to one or more of the smart devices using a radio communication network that is available at least in the smart home environment 100. Communication protocols used by the radio communication network include, but are not limited to, ZigBee, Z Wave, Insteon, EuOcean, Thread, OSIAN, Bluetooth Low Energy and the like. In some implementations, the hub device 180 not only converts the data received from each smart device to meet the data format requirements of the network interface 160 or the networks 162, but also converts information received from the network interface 160 or the networks 162 to meet the data format requirements of the respective communication protocol associated with a targeted smart device. In some implementations, in addition to data format conversion, the hub device 180 further processes the data received from the smart devices or information received from the network interface 160 or the networks 162 preliminary. For example, the hub device 180 can integrate inputs from multiple sensors/connected devices including sensors/devices of the same and/or different types, perform higher level processing on those inputs—e.

Moreover, Z Wave and Zigbee devices are connected and controlled using a hub, while Wi Fi devices can be connected directly to your home network and controlled with an app. Finally, Z Wave and Zigbee devices use AES 128 encryption, and since they operate in a closed system with a dedicated hub, they offer more security than Wi Fi devices. Any smart security system worth its salt offers components that work together in a seamless
environment and can be manipulated using customized rules. For example, you can create rules to
have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered. Some systems store recorded video locally on an SD card or a solid state drive, while others offer cloud storage. Locally stored video is a good choice for do it yourselfers on a budget, but you have to be careful not to overwrite video you may need later.

The snapshots are extra handy when facial recognition is wrong — which didn't happen often, to be fair. First, the app asked me to identify my family and close
friends multiple times from photos the Hello took. You can do this for anyone who comes to your door. I tagged my husband four times, for example, and my son six times. In the Nest app's Familiar Faces gallery, you can tap Select, choose all the instances of the same person, and tap Merge to combine them. After that, it worked pretty smoothly, but it did
misidentify my husband one night as my son's best friend, a 6 year old African American boy who wears glasses.
