Safety network of things

A method implemented by a client device, comprising:

• transmitting a registration request to a server, the registration request indicating a device identifier of the client device, an Internet address of the client device, a physical location of the client device, and an identification of a first sensor of the client device;
• receiving a recording request from the server, the recording request identifying the first sensor;
• recording data with the first sensor to produce a recording, at least in part based on the recording request;
• and
• transmitting the recording to the server.

A non-transitory, computer-readable medium encoded with instructions that, when executed by a processing unit, cause the processing unit to perform operations comprising:

• receiving a device registration request from a client device, the device registration request indicating a device identifier of the client device, an Internet address of the client device, a physical location of the client device, or an identification of at least one sensor of the client device;
• receiving an event notification indicating a location of an event;
• determining a geofence, at least in part based on the location of the event and a distance from the location;
• determining that the client device is within the geofence, at least in part based on the physical location of the client device;
• transmitting a sensor selection request to a public safety device, the sensor selection request indicating the identification of the at least one sensor and at least one of the physical location of the client device or a distance of the client device from the event;
• receiving a sensor selection response from the public safety device, the sensor selection response indicating the at least one sensor;
• and
• transmitting a recording request to the client device, the recording request identifying the at least one sensor.
