FIG. 3B illustrates various data structures used by some implementations, including an event record 3168 i, a user profile 3163 i, and a device profile 3165 i. The event record 3168 i corresponds to an event i and data for the event i. In some instances, the data for motion event i includes event start data 31681 indicating when and/or how the event started, event segments data 31682, raw video data 31683, event end data 31684 indicating when and/or how the event ended, event features data 31685, scene features data 31686, associated user information 31687, and associated devices information 31688. In some instances, the event record 3168 i includes only a subset of the above data. In some instances, the event record 3168 i includes additional event data not shown such as data regarding event/motion masks.
