Systems, methods, and devices described in the present disclosure provide technology for detecting features of interest depicted in a video stream supplied by a camera-equipped drone and adjusting the flight pattern of the drone to increase the amount of time in which the features of interest are within the line of sight of the drone. In addition, the present disclosure provides technology for detecting when events of interest occur at the features of interest and alerting personnel when the events occur. In some examples, the technology of the present disclosure also determines a format for an alert (e.g., a push notification) based on an event type so that personnel who receive the alert are apprised of the urgency of the event based on the format.
