A chemical, biological, radiological, and nuclear weapon detection system is disclosed that comprises an array of spatially-disparate hazardous material sensors and an array of spatially-disparate video cameras. The telemetry from the sensors and the video feed from the cameras are all fed back to a centralized system control center. When the illustrative embodiment suspects that an attack has occurred, it switches the feed from the video cameras in the vicinity of where the attack is believed to occur to a monitor. This enables the personnel who monitor the illustrative embodiment to further verify the attack.
