Physical Access Control, Anti-Tailgating & Crowd Management Solutions
Why Physical Security Entrances Matter
Electronic access control verifies credentials — but without a physical barrier, a determined individual can simply follow an authorized person through an open door (tailgating). Security entrances close this gap, ensuring that only verified individuals pass through controlled entry points.
NSC installs and maintains a comprehensive range of security entrance systems for corporate lobbies, government facilities, utilities, cultural properties, schools, transit hubs, and any environment where physical access control is essential. All systems integrate with access control, visitor management, and video surveillance for unified management.
Types of Security Entrances
NSC offers the full spectrum of security entrance solutions:
Optical Turnstiles (Speed Gates)
Use infrared beams and retractable barriers to control access in modern lobby environments. Professional, architecturally elegant appearance with effective tailgating and piggybacking prevention. Available in retractable barrier, swing glass, and arm barrier configurations.
Full Height Turnstiles
Maximum physical deterrence for perimeter entry points and high-security locations. Designed for harsh outdoor environments requiring the highest level of physical access control.
Tripod Turnstiles
Economical solution for crowd control at guarded entry points — stadiums, construction sites, parking facilities, and transit terminals.
Automatic Revolving Doors
Security-integrated revolving doors replacing standard manual doors, providing controlled entry with an impressive architectural presence.
Access Gates (ADA Compliant)
Accommodate wheelchairs, carts, bicycles, and special access needs while maintaining access control integration.
Anti-Tailgating and Multi-Factor Authentication
Every NSC security entrance can be configured with tailgating and piggybacking detection. Systems also support two- or three-factor authentication — combining card or credential verification with PIN entry or biometric confirmation for the highest security assurance levels.

Yes. NSC integrates turnstiles with a wide range of access control platforms assessed during the consultation.
How do turnstiles handle emergency evacuation?
