A server system can receive an assertion of an alarm condition from a security system that processes sensor signals from sensors and that triggers the alarm condition. The server system is can send messages to determined nearby sensors to start sending data back to the server system according to the alarm condition. The server system can analyze sensor data received from the sensors. The analysis includes a verification of the alarm condition, a determination of how often queried data is requested, and a determination of which of selected data received from selected sensors to forward to one or more mixed reality devices. The server system can forward data to the one or more mixed reality.
