Access Control
Access control systems secure doors, manage credentials, and enforce entry policies across commercial facilities. Build a scalable deployment with the right combination of controllers, readers, credentials, and door hardware.
Plan Your Deployment
- Door count and expansion requirements
- Reader type (card, keypad, biometric) and credential format
- Fail-safe vs fail-secure hardware design
- Power, cabling, and network connectivity planning
- Multi-site governance and consistent standards
