A video camera in the Fresh Fuel Storage room takes pictures at intervals if the Balanced Magnetic Sensor (BMS) detects the door opening. Also, when the camera detects image changes, it takes pictures. Image data stored in the Data Collection Computer are transferred to the Data Storage Computer over the local Intranet, then to the Data Server at the remote site via a VPN (Virtual Private Network) over the Internet. Data are reviewed by the Data Review Stations.
