Michigan Security Systems is your authorized CDVI dealer and installer. We design, install, program, and service the complete CDVI product line — ATRIUM A22 IP controllers, KRYPTO high-security systems, CENTAUR enterprise software, STRATUS cloud access control, RADIUM wireless, biometric readers, and electronic locking — for commercial businesses across Michigan, Ohio, and Indiana.
As an authorized CDVI dealer and installer, Michigan Security Systems provides the complete CDVI product line — from ATRIUM A22 IP controllers and KRYPTO high-security systems to CENTAUR enterprise software, STRATUS cloud, RADIUM wireless, and ievo biometric readers.
The CDVI ATRIUM A22 is the core of the ATRIUM system — a powerful 2-door IP controller with a built-in web server, integrated power supply, and metal-cased construction. One A22 controls two doors, halving both hardware costs and installation time. ATRIUM systems scale up to 500 doors and 10,000 users by networking up to 50 A22 controllers per site, all managed from any web browser or the included free software.
CDVI KRYPTO is an end-to-end high-security access control ecosystem built around the A22K controller and matching KRYPTO readers. Using AES military-grade encryption and DESFire EV2/EV3 smart credentials, KRYPTO completely eliminates the risk of card cloning — the most common vulnerability in legacy 125kHz proximity systems. High security is built into the hardware from day one, with no complex configuration required.
CDVI CENTAUR is a comprehensive enterprise-grade access control management software platform designed for large, complex installations. From single-door deployments up to 2,048 doors across multiple sites, CENTAUR grows with your organization. It delivers advanced modules for time & attendance, visitor management, guard tour, parking management, live floor plan monitoring, and burglar alarm integration — all from a single management console.
CDVI STRATUS is a cloud-hosted access control management platform that puts complete system management in the palm of your hand. Manage users, credentials, and door schedules from any internet-connected device without the complexity of an on-premise server. STRATUS is ideal for Michigan businesses that want the power of CDVI's ATRIUM hardware with the convenience and flexibility of cloud-based administration — perfect for multi-location operations and remote property management.
CDVI RADIUM provides reliable wireless access control for doors where running new wiring is impractical or cost-prohibitive. RADIUM AES adds AES encryption to the wireless signal for applications requiring heightened security. Ideal for retrofitting access control into existing Michigan facilities — historic buildings, leased spaces, and multi-tenant properties — without the disruption and cost of in-wall cable runs.
CDVI offers a comprehensive range of credential readers and authentication hardware for every application. KRYPTO readers deliver encrypted DESFire EV2/EV3 security for the A22K system. Standard MIFARE and 125kHz proximity readers provide value-tier solutions. Mobile-PASS Bluetooth credentials let authorized users unlock doors with their smartphone. For the highest level of identity verification, ievo biometric readers deliver fingerprint and facial recognition access control.

CDVI is a global access control manufacturer operating in over ten countries, with a strong North American presence through CDVI Americas. Their ATRIUM platform has earned a reputation among security installers for its exceptional ease of installation — modules auto-detect and configure themselves, the integrated web server eliminates dedicated software for basic management, and the pre-assembled power supply means less time on-site and faster commissioning.
The KRYPTO product line addresses one of the most critical security vulnerabilities in today's access control landscape: card cloning. Legacy 125kHz proximity cards can be cloned in seconds with readily available hardware. CDVI KRYPTO's DESFire EV2/EV3 encryption makes cloning technically impossible, providing Michigan businesses with genuine credential security rather than a false sense of protection.
Michigan Security Systems brings certified CDVI installation expertise to your project — ensuring your system is designed correctly, installed to code, programmed efficiently, and supported for the long term. We recommend the right CDVI tier for your specific Michigan facility, budget, and security requirements.
Configure and manage your ATRIUM system from any web browser on any device — no dedicated software installation required for basic administration.

Common questions Michigan businesses ask about CDVI access control installation, products, and our services.
Yes. Michigan Security Systems is an authorized CDVI access control installer serving Michigan, Ohio, and Indiana. Our technicians are trained on the full CDVI product line — ATRIUM A22 and A22K controllers, KRYPTO high-security hardware, CENTAUR enterprise software, STRATUS cloud, RADIUM wireless, and the complete range of CDVI readers, credentials, and ievo biometric hardware.
ATRIUM standard uses the A22 controller with conventional MIFARE or 125kHz proximity credentials. KRYPTO is CDVI's high-security tier, built around the A22K controller and matching KRYPTO readers using DESFire EV2/EV3 AES-encrypted credentials. The key difference: KRYPTO credentials cannot be cloned. If your facility handles sensitive data, assets, or people requiring high-assurance identity verification, KRYPTO is the right choice.
A single CDVI ATRIUM site supports up to 500 doors and 10,000 users by networking up to 50 A22 or A22K controllers together. Each controller handles 2 doors. For enterprise deployments requiring more than 500 doors or complex multi-site management, CDVI CENTAUR software scales up to 2,048 doors across multiple locations. Michigan Security Systems will design the right architecture for your Michigan facility.
Yes. System takeovers — replacing legacy access control hardware with CDVI ATRIUM — are a specialty of ours. We assess your existing door hardware, determine what can be reused (strikes, maglocks, wiring), install the new CDVI controllers and readers, and migrate your credential database. Call 586-466-4490 to discuss your existing system and get a takeover proposal.
Mobile-PASS is CDVI's Bluetooth-enabled smartphone credential system, compatible with the A22K KRYPTO controller and KRYPTO readers. Authorized users unlock doors with their smartphone using one of five methods: tap, twist, pull, voice command ("open door"), or automatic detection as they approach. Mobile-PASS uses end-to-end military-grade encryption, so it delivers the full security of KRYPTO without a physical credential.
We specialize in commercial and industrial access control installations. We serve office buildings, warehouses, manufacturers, retail businesses, schools, municipalities, healthcare facilities, cannabis dispensaries, automotive dealerships, hotels, government facilities, and multi-site organizations. Every project is custom-engineered for the specific facility — we do not install residential DIY systems.
Michigan Security Systems is headquartered in Macomb County and serves the Metro Detroit commercial market as an authorized CDVI access control installer. We install CDVI ATRIUM A22 and A22K systems for businesses throughout Warren, Sterling Heights, Clinton Township, Mount Clemens, St. Clair Shores, Shelby Township, Chesterfield Township, New Baltimore, Roseville, and the broader Metro Detroit commercial market.
CDVI ATRIUM's web-server-based management is particularly valued by Metro Detroit businesses that need a capable, easy-to-manage system without the expense of a dedicated software server. The A22's two-door-per-controller design keeps hardware costs in check for smaller Michigan businesses while leaving room to scale.
Card cloning has become an increasingly accessible threat to Michigan businesses using legacy 125kHz proximity systems. Devices capable of cloning standard access cards are inexpensive and widely available. CDVI KRYPTO's DESFire EV2/EV3 technology uses AES encryption that makes cloning technically impossible — giving Michigan businesses real security, not just the appearance of it. Michigan Security Systems recommends KRYPTO for any Michigan facility where unauthorized credential duplication poses an unacceptable risk.
Michigan organizations managing multiple locations — regional office networks, healthcare systems, school districts, and manufacturing campuses — benefit from CDVI CENTAUR enterprise software. CENTAUR consolidates access control for up to 2,048 doors across multiple sites into a single management interface, with advanced modules for time & attendance, visitor management, guard tour, and live floor plan monitoring.
