Data Center Intrusion Detection Design
Tier III/IV data centers require dual-control access, biometrics at the cage, 100% CCTV coverage of every aisle, and intrusion sensors on every hall.
Data center security is among the strictest in the security industry. Tier III and IV facilities require: dual-control access at every entry (two credentials, two persons), biometric verification at cage / suite level, 100% CCTV coverage of every aisle / row / cabinet rear, intrusion sensors on every hall and ceiling void, environmental monitoring (smoke / heat / leak), and network segmentation that isolates CCTV LAN from customer VLANs. Retention: 90+ days, often 1 year for compliance audits.
Intrusion detection planning maps every entry point, occupied zone, and vulnerable surface to the right sensor: door / window contacts at the perimeter; PIR or dual-tech for interior motion; beam barriers along fence lines; glass-break sensors at large windows; vibration sensors on vaults / safes. Alarm zones group sensors so the panel can arm portions separately (
Data Center intrusion detection pain points
- 01Mantrap + dual-control entry (anti-tailgating, two-person rule)
- 02Cage-level biometrics (fingerprint or iris) on customer suites
- 03100% aisle coverage at row-end + ceiling void intrusion
- 04OT/IT segmentation: CCTV LAN must NOT see customer data plane
- 05Tier III/IV uptime requires redundant NVR, dual PoE switches, A+B power feeds
Discipline capabilities
- PIR placement covering interior choke points without overlap waste
- Door / window contacts on every perimeter opening
- Beam barriers across fence lines + driveway gates
- Glass-break detectors on shopfront / lobby glazing
- Vibration / shock sensors on vaults, safes, ATM enclosures
- Alarm zoning (perimeter / interior / 24h-armed) to support stay vs away modes
- Grade 2 vs Grade 3 (EN 50131) panel + polling redundancy choice
