Methods, systems, and apparatus, including computer programs encoded on computer storage media, for enhanced sensors. One of the methods includes accessing i) data for a detected event that was detected using first sensor data captured by a first sensor at a property and ii) second sensor data captured by a second sensor for the property, the first sensor having a different type than the second sensor; providing, to an artificial intelligence model trained to determine whether to provide a notification about the detected event, the data for the detected event and the second sensor data to cause the artificial intelligence model to generate output; receiving, from the artificial intelligence model, the output that indicates whether to provide a notification about the detected event; and performing one or more actions using the output that indicates whether to provide a notification about the detected event.
