The Physical Security Interoperability Alliance (PSIA) is a global consortium of more than 65 physical security manufacturers and systems integrators focused on promoting interoperability of IP-enabled security devices and systems across the physical security ecosystem as well as enterprise and building automation systems.〔http://www.psialliance.org/org.html〕 The PSIA promotes and develops open specifications, relevant to networked physical security technology, across all industry segments including video, storage, analytics, intrusion, and access control. Its work is analogous to that of groups and consortia that have developed standardized methods that allow different types of equipment to seamlessly connect and share data, such as the Universal Serial Bus (USB) and Bluetooth. ==PSIA Specifications== The PSIA has created seven complementary specifications that enable systems and devices to interoperate and exchange data and intelligence.〔http://psialliance.org/SpecificationsOverview.html〕 Three of these specifications are the “reference works” for the family of specifications. These are the Service Model; PSIA Common Metadata & Event Model; and the PSIA Common Security Model. These “common models” define and describe various security events as well as computer network and software protocols relevant to security devices and systems.〔 The other four PSIA specifications correspond to domains in the security ecosystem. These are the IP Media Device specification, Recording and Content Management specification, Video Analytics specification and Area Control specification. These base their communications about security events on the PSIA Common Metadata & Event Model, one of the reference works described above.〔 PSIA specifications are expected to become more critical to security system architecture as major users integrate video surveillance, access and area control, mobile devices and local and cloud-based storage across a common information technology platform.〔http://www.sdmmag.com/articles/88600-how-new-technologies-and-standards-like-onvif-and-psia-are-affecting-video-management-systems-vms?v=preview〕 PSIA has a liaison with the International Electrotechnical Commission on two specifications for access control and video.〔http://www.iec.ch/dyn/www/f?p=103:46:0::::FSP_ORG_ID,FSP_IECPARTNER,FSP_LANG_ID:7314,1,25〕 The access control specification, IEC 60839-11-1, pending a vote, is expected to have a big impact on the manufacturing and interoperability of thousands of access control systems.〔http://www.imsresearch.com/press-release/access_control_market_open_to_the_idea_of_open_standards〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Physical Security Interoperability Alliance」の詳細全文を読む スポンサード リンク
