Physical security hardware encompasses three primary types of devices. The first type consists of locks and keys, where a key serves as a security token providing access to a secured area. The second type involves physical barriers such as fences, gates, or walls, which are installed to establish a secure perimeter and deter potential intruders. The third type encompasses video surveillance, which includes the use of closed-circuit television (CCTV) cameras and video recording equipment. These devices are utilized to monitor physical spaces in real time and also for post-incident review, providing an additional layer of security and surveillance.
