Yes, more cameras
Two cameras are being installed on top of the roof of Bldg. 54. Yesterday, camera housings were installed, on each of the south corners. One is pointed at Masseeh Hall (W1), and one is pointed at Harvard Bridge. Thomas W. Komola from the Security and Emergency Management Office said the footage from the cameras would be used under the Security Office’s standard policy: access to the footage is only available at written request of MIT Chief of Police John DiFava.
