Event detection, event notification, data retrieval, and associated devices, systems, and methods

A method, comprising:

• detecting an event via a first sensor of a mobile surveillance unit and a second, different sensor of the mobile surveillance unit, the mobile surveillance unit including a head unit including each of the first sensor and the second, different sensor;
• responsive to the detected event, conveying, from the mobile surveillance unit to a remote device over at least one metered connection, a first data set comprising video data associated with the event and captured by the first sensor;
• responsive to the detected event, conveying, from the mobile surveillance unit to the remote device over the at least one metered connection, a second, different data set comprising image data associated with the event and captured by the second, different sensor;
• and
• responsive to the detected event, conveying, from the mobile surveillance unit to another remote device over the at least one metered connection, a third data set different than the first data set and the second, different data set.

A system, comprising:

• a mobile unit comprising:
• a first sensor at a sensor location and configured to sense an event and capture first data comprising video data associated with the event;
• and
• a second sensor at the sensor location and configured to sense the event and capture second, different data comprising image data associated with the event;
• the system configured to:
• convey, responsive to the sensed event, the first data from the mobile unit to a remote device via at least one metered connection;
• convey, responsive to the sensed event, the second, different data from the mobile unit to the remote device via the at least one metered connection;
• and
• convey, responsive to the sensed event, third data different than the first data and the second, different data from the mobile unit to another remote device via the at least one metered connection.
