Access Control Systems

Control & Track Entry
Respond Quickly to Security Threats
Access Control Systems allow a manager to respond quickly to a security problem — be it a lost card or disgruntled ex-employee — by removing an individual’s code, or credential, from the system. Higher end systems allow time zone control (time of day and day of week), reports by individual or door and controlled access during holidays.


KST Offers Two Types of Access Control

Self-Contained Electronic Locksets
Provide low-cost control and documentation of entry (optional) into an office, storeroom, or computer room.
Networked Access Control Systems
Our line of Continental Access Systems can control up to 1,024 doors, more than 100,000 employees, is able to fully utilize Ethernet networks for communication, and can generate access reports by employee, door and date.


Video Security Systems

Detect, Deter and Document Internal & External Threats Against Your Business
Companies can lose hundreds of thousands of dollars from internal theft and external loss. State of the art cameras can be mounted in plain view or hidden to detect illegal activity. This is one of the best investments your company can make.


Medeco High Security Locks

Control Unauthorized Key Duplication
Prevent the most common reason for the compromise of a master key system and your security — unauthorized key duplication.
