Access Control Systems

Card, mobile, and biometric access control with electronic locks, secure credentials, and audit reporting for any facility.

Quick answer

ROI International designs and installs access control systems — card, fob, mobile, and biometric credentials with electronic door locks, controllers, and audit reporting — for commercial, government, and multi-site facilities across Phoenix and all of Arizona.

What's included

Card, fob, mobile-credential, PIN, and biometric access
Electronic locks, electric strikes, maglocks, and electrified hardware
Cloud or on-premise management for single and multi-site organizations
Time schedules, access levels, and instant credential revocation
Emergency lockdown and anti-passback capabilities
Full audit trails and integration with video surveillance

Control who goes where — and know exactly who did

Access control replaces vulnerable physical keys with electronic credentials you manage centrally. ROI International designs and installs card, mobile, and biometric access control systems for facilities across Arizona — giving you precise control over every door, with a complete audit trail of every event.

When someone leaves or a card is lost, you revoke access in seconds instead of rekeying locks. When you need to know who opened a door at 2 a.m., the system tells you.

What we install

Credential options — proximity/smart cards, fobs, mobile (phone) credentials, PINs, and biometrics
Door hardware — electric strikes, maglocks, and electrified locksets with request-to-exit and door position sensing
Controllers & software — cloud-based or on-premise, for single doors to multi-site enterprises
Policies — time schedules, access levels, anti-passback, and emergency lockdown
Reporting — full audit trails of who accessed what, where, and when
Integration — linked to video surveillance and alarms

Built for security and accountability

Every access point is installed to life-safety and code requirements (including proper egress), cabled and tested with certified low-voltage wiring, and configured to your security policy. And because ROI also provides surveillance and network infrastructure, your access control is part of one unified, accountable security system — not an isolated add-on.

Access Control — frequently asked questions

How does an access control system work?

An access control system replaces or augments physical keys with electronic credentials — cards, fobs, mobile phones, PINs, or biometrics. Readers at each door check the credential against rules you set (who, where, and when), then unlock electrified hardware if access is allowed, while logging every event for audit. ROI designs, installs, and configures the readers, controllers, locks, and software.

Can I manage access control for multiple locations?

Yes. ROI deploys cloud-based and enterprise access control that lets you manage credentials, doors, schedules, and reporting across many sites from a single dashboard — ideal for organizations with multiple buildings or locations.

What happens if I lose a card or an employee leaves?

Lost or former-employee credentials are revoked instantly from the management software — no need to rekey locks. You can also issue temporary or scheduled access for contractors and visitors, and pull an audit trail of exactly who accessed which door and when.

Can access control use phones instead of cards?

Yes. ROI installs mobile-credential systems that let staff unlock doors with their smartphone over Bluetooth or NFC, which reduces the cost and hassle of managing physical cards while improving security.
