The team at TURNSTILES.us is honored to provide our Turnstile and Access Control Solutions. Please find featured equipment information, photos, and project documentation below. We appreciate the opportunity to secure your facility.

We aim to develop a scalable security solution for Federal Court Buildings, with options based on security level, user experience, and cost.

Tiered Access Control Solutions

The following tiers represent scalable security levels that can be applied across all entry points.

Tier 1 – Basic Control
Minimal optical sensors, cost-focused, small footprint, low glass

Tier 2 – Balanced Security
Strong optical detection, great cost/performance, high or low glass

Tier 3 – High Security
High-risk zones, advanced position tracking, federal-grade control, mantrap upgrades

Facility Security Layout by Area

Project Overview

This project includes security upgrades across multiple entry points within the building, including:

a. West Entrance (Atrium – Primary Public Entry)
b. South Entrance (Mass Ave – Limited / Potential Daily Use)
c. East Entrance (2nd St – Staff / Secondary Entry)
d. Interior Security Elements (elevator lobbies, controlled zones)

Each location has unique constraints related to:

Queueing and circulation
ADA accessibility
Screening equipment integration
Blast / ballistic considerations

Application by Area

Recommended Application by Area

West Entrance (Main Public) → Tier 2 or 3

South Entrance (Limited Use) → Tier 1 or 2

East Entrance (Staff Entry) → Tier 2 or 3

Interior Zones → Tier varies by security level

West Entrance (Atrium – Primary Public Entry)

Recommended: Tier 2 or Tier 3

Rationale:

High public traffic
Requires strong detection and throughput
Visible security presence

Suggested Technologies:

Optical gates (3-Lane Array & 4-Lane Array)
Barrier Partitions
Metal detection
X-Ray baggage screening

South Entrance (Mass Ave – VIP / Limited Use)

Recommended: Tier 1 or Tier 2

Rationale:

Lower traffic
Intermittent, potentially daily use
Cost-sensitive

Suggested Technologies:

Optical gates (4-Lane Array)
Metal detection
X-Ray baggage screening

East Entrance (2nd St – Staff / Secondary Entry)

Recommended: Tier 2 or 3

Rationale:

Daily use, frequent use by staff
Requires security and flow in a limited space

Suggested Technologies:

Optical gates OR Mantrap Cubicles (indoor/outdoor)
Metal detection
X-Ray baggage screening

*NOTE: Building needs to be made ADA.
Multiple ways to solve stairs and corridor area.

Interior Security Zones (Elevator Lobbies, Controlled Areas)

Recommended Tier: Tier varies

Rationale:

Depends on access level
Can require higher containment
Consider a uniform level as other tier selections

Suggested Technologies:

Optical gates
Partition barriers

Alternative Configurations and Enhancements

Tier 3+

The dPass Turnstile is a two-step validation system utilizing the same advanced tracking technology as the dFlow, configured as a mantrap for controlled, single-user access. It is commonly deployed in high-security environments such as airports, border control, and secure facility lobbies.

Tier 3+

A mantrap monitors and controls two interlocking doors that cannot be opened simultaneously. Either door can be unlocked and opened, as long as the other door is locked and closed. Between these interlocking doors is a small, secure space, which only admits one person at a time. Ideal for high-security areas.
