A device may receive, from another device, an image that depicts one or more events occurring at a location. The device may detect an event of the one or more events depicted in the image. The device may determine a first score that indicates a likelihood that the event is an anomalous event. The first score may be based on first data received from the other device. The device may determine a second score that indicates a similarity between the event and another event. The second score may be based on second data received from the other device. The second data may comprise data from a sensor, a wearable device, a mobile device, and/or a handheld device. The device may perform an action based on the first score or the second score.
