Which physical security measure is specifically installed at entrances or around sensitive areas to block or slow vehicles that might try to ram the building?
Access-control vestibule
Video-surveillance cameras
Bollards
Badge reader
Bollards are sturdy vertical posts-often steel-reinforced-that are embedded in the ground to withstand vehicular impact. Their purpose is to prevent or mitigate vehicle-borne attacks or accidental crashes into a facility. Badge readers, access-control vestibules, and video-surveillance cameras all enhance security, but none is designed to physically stop a moving vehicle.
