Abstract: Various arrangements are provided for using an unmanned aerial vehicle with a home automation system. The home automation host system may determine that a home automation event has occurred. The system may determine to perform unmanned aerial vehicle (UAV) surveillance of the home in response to the home automation event. Deployment of a UAV may be triggered in response to determining to perform the UAV surveillance of the home. Video may then captured by the UAV of a portion of the home, possibly corresponding to the location of the home automation event. The video captured by the UAV of the portion of the home in association with an indication of the home automation event that triggered deployment of the UAV may be recorded.
