Integration Partners


EXgarde 4.1’s integration with both Milestone’s XProtect Enterprise and Corporate video management software is part of a wider drive to unite traditionally disparate components of business security. Recognising the power of compatible systems, TDSi and Milestone’s systems are designed to be highly complementary to one another, providing excellent results and superb value for money. In the case of the CCTV integration, users can view live video from any camera within the EXgarde Explorer window, so an incident reported by the access control system, for example, can immediately be investigated visually.

Microsoft® Active Directory

TDSi now intergrates directly with Microsoft® Active Directory, so physical security systems can be directly synchronised with logical security and the central business facility database can provide an overall view of any situation. as users gain access their location is logged with Microsoft®Active Directory, which is the keystone to many modern build control systems. Any security breach can also trigger IT system protocols that control the level of access available in certain areas, to minimise the possibility of unwarranted removal of data. This offers a superb way to integrate physical security with the IT security systems to provide a total picture of organisational security.
