Perimeter Security MAC Portals Turnstiles & Access Control Technology

Turnstiles like those in our patented Modular Access Control (MAC) Portal have been used for a wide range of purposes for decades. Many perimeter security installations on construction sites use turnstiles and are often built into permanent structures. Requiring expensive construction, long timelines, and limited feasibility because they need to be built and are often torn down after a project ends. What separates Modular Security Systems Inc. (MSSI) from the competition is the portability of our MAC Portals, their turn-key installation, and the lack of need for construction on site.

Once onsite, installation is a cinch! Depending on the site and specifications, the patented MAC Portal can be dropped into a fence line, connected to the electric, and the MAC is fully operational. The portability and ease of installation make the patented MAC Portal the perfect solution for industrial and commercial construction sites in the US and around the world. 

A major benefit of having a MAC Portal delivered to your site is the lead time. The MAC Portal can be delivered within 6-8 weeks from receipt of a purchase order. Built fully integrated with any type of site-specified access control technology these portable perimeter security solutions with turnstiles offer the perfect solution for both temporary and permanent installations.
