Security system installers face a constant challenge: delivering robust physical security while keeping project costs within budget.
The PROMI keypad/reader by CDVI solves this dilemma. As a cost-effective, standalone access control device, PROMI combines modern high-frequency credentials, dual-frequency compatibility, flexible multi-factor authentication, and a seamless upgrade path to centralized systems—all in a compact, weather-rated housing.
High-Frequency security (13.56 MHz) at an entry-level price
Transitioning to secure credential technology should not require a massive capital expenditure. PROMI makes high-frequency 13.56 MHz credential technology accessible for standalone installations, allowing installers to deliver advanced encryption standards without forcing clients to invest immediately in a full controller-based infrastructure.
Dual-Frequency compatibility: Seamless 125 kHz to 13.56 MHz migration
For retrofit projects, replacing an entire cardholder database overnight is costly and disruptive. PROMI features dual-frequency capability, reading both:
- Legacy 125 kHz Proximity Credentials: Maintains support for existing cards and fobs during phased upgrades.
- Modern 13.56 MHz Credentials: Enables installers to issue higher-security cards for new users or high-security zones.
This backwards compatibility allows businesses to migrate progressively toward modern security standards without discarding working hardware.
Multi-Factor authentication for critical doors
Not all doors require the same level of protection. PROMI adapts to varying security requirements by offering flexible authentication modes:
- PIN-Only Access: Ideal for standard staff entrances or basic keyless entry.
- Card/Fob-Only Access: Streamlines high-traffic entry points.
- Card + PIN (Two-Factor Authentication): Adds an extra layer of security for sensitive areas such as server rooms or executive suites.
Future-Proof security: Transition from standalone to wiegand mode
A standalone keypad today should not restrict access control capabilities tomorrow. PROMI features an onboard Wiegand output mode that can be activated with a single button press.
By switching to Wiegand mode, the unit transforms from a local door controller into a network reader connected to an access control panel. This unlocks advanced enterprise features:
- Centralized User Management: Manage permissions across multiple doors remotely.
- Audit Trails & Event Logs: Track real-time door activity and access history.
- Advanced Logic: Implement anti-passback, system-wide lockdown, and time-based schedules.
- Hardware Preservation: Upgrade the backend system without replacing the door hardware.
Designed for indoor and outdoor environments
To simplify inventory and product selection, PROMI is engineered for versatility across different installation environments:
- Indoor Commercial Spaces: Office suites, restricted storage, and staff-only rooms.
- Outdoor Perimeter Entrances: Commercial gates, exterior building doors, and weather-exposed entryways.
