CASE STUDY
Server Room and Data Centre: Two-Factor Access and Environmental Monitoring
Card plus finger-vein two-factor entry, interlocked double doors, full entry logging, and water leak and temperature alarms.
Financial institution server room (client name withheld under confidentiality arrangement)
Background
The client's server room sits inside a commercial building, and entry must satisfy internal audit requirements: no single-person entry, a record for every door opening, and visitors escorted by staff at all times. The original card-only system could not meet the audit.
Design
The outer and inner doors are interlocked (mantrap), so only one door can open at a time. Entry requires a card plus finger-vein verification; exit is by push button, also logged. Visitor cards carry a validity window and an assigned escort, expiring automatically when the window ends. Water leak sensors and temperature and humidity monitoring were added inside the room, with alerts sent over the network and by phone when readings go out of range.
Challenges
The server room walls are plasterboard, so magnetic locks could not be mounted directly. We installed reinforcement brackets with metal backing plates and concealed all cabling. The access controllers and monitoring host sit in a dedicated rack powered by a UPS, so door events are still recorded during a power failure.
Result
Audit reports can be exported directly from the system, covering who entered, when, with which credential, and accompanied by whom. The client subsequently extended the same standard to a second server room and incorporated our door schedule and wiring diagrams into its internal asset documentation.
