Portable Turnstiles for Access Control and Perimeter Security by MSSI

Modular Security Systems Inc. (MSSI) offers our customers a safe and secure entry point and exit for industrial and commercial construction projects using our modular guardhouse with access control turnstiles, which is perfect for any location. MSSI offers the Patented Modular Access Control (MAC) Portal that can be integrated into an existing security perimeter or act as a stand-alone unit. Utilizing our portable guard offices with turnstiles a security guard can monitor, from a climate-controlled guard office, the flow of traffic entering and exiting your construction site.

Since the creation of our portable security solution the MAC Portal in the early 2000's, MSSI has delivered our brand of turnstile security to sites around the world including refineries, power plants, commercial construction sites, military installations, and ports and harbors. While turnstiles have been used for many purposes for more than a hundred years, before the MAC Portal no one had thought to make them portable by installing them in a shipping container the way that MSSI does.

Prior to the invention of the patented MAC Portal, many turnstile installations for access control security were built into permanent structures that were often very expensive and not feasible for temporary purposes. These turnstile installations were often built and then torn down because they don't meet with the final plans for the site where they are located.

When it comes to perimeter security turnstile solutions, what separates MSSI from the rest of the pack is our ability to deliver a turn-key portable perimeter turnstile that can be temporarily installed and then easily relocated to another location.
