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

A method, comprising:

• detecting, via a mobile surveillance unit positioned in an environment, an event;
• conveying, from the mobile surveillance unit, data associated with the event to an electronic device remote from the mobile surveillance unit;
• and
• conveying, from the mobile surveillance unit, video data associated with the event, image data associated with the event, audio data, or any combination thereof, in response to a request associated with the conveyed data.

A system, comprising:

• at least one sensor at a sensor location and configured to sense an event and capture one or more videos and one or more images;
• the system configured to:
• convey data related to a sensed event to a remote device;
• and
• in response to an input associated with the conveyed data, convey, to a server, the remote device, or both, a specific portion of the one or more videos captured at the sensor location without downloading every other portion of the one or more videos, the specific portion associated with the sensed event.

A system, comprising:

• a mobile surveillance unit positioned within an environment and including one or more sensors configured to detect one or more events occurring within or near the environment;
• and
• an application program configured to:
• cause, responsive to a detected event, a first data set associated with the event and captured by a first sensor of the one or more sensors to be conveyed from the mobile surveillance unit;
• and
• cause, responsive to the detected event, a second, different data set associated with the event and captured by a second sensor of the one or more sensors to be conveyed from the mobile surveillance unit.
