Physical security systems consist of hardware and software that provide security and safety. Today we can attach a variety of devices to the network and use a number of integrated software products that provide a unified solution.
For example, the integration of door access control software, emergency paging software and the latest video management software (VMS) can provide a very nice security and safety system. Now we can use IP cameras, IP sensors, IP door readers and IP paging amplifiers to provide a very complete physical security system. These IP based security systems provide similar capability to Physical Security Information Management (PSIM) software at much less cost.
