Access Control & Relays | Gerald's Tech

Access Control & Relays

Design, install, and support of secure, reliable access systems—doors, gates, intercoms, relays and schedules— with clear auditing, integrations, and documentation your team can operate confidently.

Door Hardware & Panels

  • Maglocks & electric strikes (fail-safe / fail-secure strategies)
  • Door contacts, REX/RTE sensors, emergency break-glass units
  • Controller & power design (PSU sizing, PoE, UPS, surge protection)
  • Enclosure layout, labeling, and serviceable wiring standards
  • Elevator control, turnstiles, vehicle gates & loop detectors

Credentials & Readers

  • RFID cards/fobs, PIN keypads, mobile credentials (BLE/NFC)
  • Biometrics (fingerprint/face) with privacy-aware policies
  • Reader tech (Wiegand, OSDP/secure-channel) and wiring
  • Anti-tamper, reader LED/buzzer feedback, accessibility modes

Schedules, Profiles & Governance

  • Time profiles, holidays, first-person-in (FPI) logic
  • Area/zone design, anti-passback, muster/roll-call
  • Role-based access control (RBAC) and least-privilege
  • Visitor & contractor workflows with expiries

Relays, I/O & Automations

  • Event-driven relays (door held/forced, motion, alarms)
  • Fire panel integration: release logic & failsafe egress
  • Intercoms & SIP endpoints; door buzz-through policies
  • Links to lighting, HVAC and building automations

Network & Remote Access

  • VLAN segmentation for controllers/readers; QoS and IGMP
  • Secure remote access via VPN; no exposed mgmt ports
  • Certificate management, TLS where supported
  • Monitoring, SNMP/health checks and alerting

Audit, Compliance & Retention

  • Event logs (grant/deny, door status, operator actions)
  • Reporting for HR/compliance (POPIA/GDPR-aware)
  • Data retention & privacy zones; badge lifecycle
  • Backups, restore drills, and change control
Policies tailored to your sector and local regulations.

CCTV, Alarms & Cloud

  • CCTV linkage: snapshots/bookmarks on access events
  • Alarm panel inputs/outputs, strobe/siren logic
  • Email/Teams notifications and webhooks
  • Cloud, on-prem, or hybrid controller architectures

Process & Handover

  • Discovery & risk assessment; door schedule mapping
  • Clean installation, labeling, and commissioning tests
  • Admin & operator training; quick-ref guides
  • Runbooks, SOPs, and ongoing support options

Secure Access, Done Right

From a single door to multi-site deployments, I’ll design a robust access system with clear logic, clean installs, audited events, and integrations that make daily operations easier.
