These nodes are typically equipped with the capability of using a wireless protocol to facilitate bidirectional communication with a variety of other devices in the smart home
environment 100, as well as with the server system 164. In some implementations, one or more “spokesman” nodes operate as a smart home controller. On the other hand, the devices that are battery powered are the “low power” nodes. These nodes
tend to be smaller than spokesman nodes and typically only communicate using wireless protocols that require very little power, such as Zigbee, ZWave, 6LoWPAN, Thread, Bluetooth, etc. As described, in some implementations, the smart devices serve as low power and spokesman nodes to create a mesh network in the smart home environment 100. In some implementations, individual low power nodes in the smart home environment regularly send out messages regarding what they are sensing, and the other low powered nodes in the smart home environment—in addition to sending out their own messages—forward the messages, thereby causing the messages to travel from node to node i. e. , device to device throughout the smart home network 202. In some implementations, the spokesman nodes in the smart home network 202, which are able to communicate using a relatively high power communication protocol, such as IEEE 802. 11, are able to switch to a relatively low power communication protocol, such as IEEE 802. 15.

, at a second doorbell mode. The battery is recharged when the button 706 or the button 1002 is not pressed at the first camera mode. The battery is
sized big enough so that it can charge back up in between button
presses. Stated another way, the battery may be recharged between the button presses to reach a power level that is sufficient to sustain operation of the camera module 1004 during a subsequent press on the button 1002. In some implementations, the battery is configured to sustain a predetermined number e. g.

In some implementations, the source information 503 is used by the server system 164 to perform event
detection and/or to categorize event candidates. In some implementations, the additional source information 503
includes one or more preliminary results from video processing performed by the camera 118 or 106 e. g. , categorizations, object recognitions, motion masks, etc. In some implementations, the video portion after an event start incident is detected is divided into multiple segments. In some implementations, the segmentation continues until event end information sometimes also called an “end of event signal” is obtained. In some implementations, the segmentation occurs within the server system 164 e. g. , by the event processor module 3146. In some implementations, the segmentation includes generating overlapping segments.
