Apply least privilege and remove access promptly when authorization changes.</p><h2>Design considerations</h2><p>Review door stations, call routing, image quality, audio intelligibility, mobile answering, recording, release relays, accessibility, and network security. Confirm lock type, door construction, egress, accessibility, fire requirements, environmental exposure, power, and communications.</p><h2>Integration and cybersecurity</h2><p>Coordinate access control with video, intercoms, alarms, elevators, and identity systems. Protect controllers and management accounts with segmentation, unique credentials, supported firmware, and audit logging.</p><h2>Testing and maintenance</h2><p>Test authorized and denied entry, schedules, emergency release, communications, event records, backup power, and failure modes. Train operators and review permissions regularly.</p><h2>Plan the complete entry solution</h2><p>Use qualified security, electrical, fire, and door professionals.
