Using sensor data to detect events

A method comprising:

• receiving, from a client device, first data associating a first electronic device having a first field of view (FOV) with a second electronic device having a second FOV;
• storing second data associating the first electronic device with the second electronic device;
• receiving third data indicating that the first electronic device detected a change in the first FOV;
• based at least in part on receiving the third data, generating a first message and transmitting the first message to the client device;
• receiving, within a threshold period of time of receiving the third data, fourth data indicating that the second electronic device detected a change in the second FOV;
• and
• based at least in part on the first electronic device being associated with the second electronic device, and receiving the fourth data within the threshold period of time of receiving the third data, determining not to transmit a second message to the client device.

One or more computing devices comprising:

• one or more network components;
• one or more processors;
• and
• one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, using the one or more network components, first data associating a first electronic device having a first field of view (FOV) with a second electronic device having a second FOV;
• storing second data associating the first electronic device with the second electronic device;
• receiving, using the one or more network components, third data indicating that the first electronic device detected a change in the first FOV;
• based at least in part on receiving the third data, generating a message;
• transmitting, using the one or more network components, the message to a client device;
• associating the third data with an event;
• receiving, using the one or more network components and within a threshold period of time of receiving the third data, fourth data indicating that the second electronic device detected a change in the second FOV;
• and
• based at least in part on receiving the fourth data within the threshold period of time of receiving the third data, associating the fourth data with the event.
