Bank Network Planning Design
Financial institutions follow strict regulatory specifications: facial-recognition-grade resolution at teller positions, tamper-proof DVR, 7-year retention, perimeter intrusion alarms.
Bank security is dictated by regulation more than design choice. Federal Reserve guidelines (US), Basel III banking supervision (EU), and PCI-DSS for card data all impose hard requirements: minimum pixel density at teller positions, retention windows of 30-90 days minimum (some jurisdictions 7 years for fraud cases), redundant alarm reporting, and 24/7 monitored intrusion detection. Branches need vestibule mantraps with bullet-resistant interlocks.
Network planning for security underpins everything: IP addressing for cameras + intrusion panels + access controllers, VLAN segmentation isolating CCTV / OT / customer networks, PoE budget calculations for the right switch tier, UPS sizing for the longest acceptable outage, cable routing through plenum + conduit + outdoor armoured runs, and bandwidth provisioning for 4K / 8MP camera streams with H.265 compression.
Bank Network Planning pain points
- 01Facial-recognition-grade resolution at teller (≥250 px/m per EN 62676-4)
- 02ATM camera fields-of-view captured both transaction + face-of-user simultaneously
- 03Vault + safe deposit rooms require dual-control access (two cards + PIN)
- 04Branch perimeter intrusion sensors armed automatically at close-of-business
- 05Reporting to monitoring station + police is regulated — must be redundant (cellular + IP)
Discipline capabilities
- IP addressing schema (subnetting) per camera / access / intrusion / monitoring zones
- VLAN segmentation isolating CCTV from OT / customer / public WiFi traffic
- PoE budget per switch tier (Type 1/2/3/4) and total PSE wattage headroom
- UPS sizing for 30 min / 1 h / 4 h / 24 h target backup time
- Cable type selection (Cat5e / Cat6 / Cat6a) per run length + PoE class + future-proofing
- Bandwidth provisioning for 4K H.265 streams + simultaneous remote viewers
- NVR storage tiering + retention windows + cold storage / cloud archive
