Card Key Access Systems

Smart Access. Secure Spaces.

Managing who enters and exits your business is a vital part of maintaining a safe and secure workplace. At Low Voltage Systems, Inc., we provide reliable electronic card access systems that allow you to monitor, restrict, and document access across your facility. Each employee is assigned a unique key card, and every entry is logged—giving you full visibility and control.



Whether you’re overseeing a single entrance or multiple secure zones, our customized access control solutions make it simple to protect your staff and assets.

Secure Every Entry Point with Confidence

An access control system offers more than just convenience—it’s an essential layer of protection against unauthorized visitors, internal threats, and potential theft. Key features and benefits include:



  • Full Control Over Your Facility
    Restrict access to the entire building or specific rooms based on roles or clearance levels.
  • Custom Permissions by Time and Date
    Grant or limit access during certain hours or days—for example, for cleaning crews, contractors, or shift-based teams.
  • Visitor and Employee Tracking
    Know who accessed which areas and when, with detailed logging for audits or incident reviews.
  • Parking Lot and Elevator Access
    Extend access control to garages, elevators, and restricted floors with integrated solutions.
