Modular Security Systems Incorporated (MSSI), is leading the way to a more secure world, one turnstile at a time. Their latest invention to recieve an official patent in the United States is the Modular Access Control (MAC) Portal. The MAC Portal begins life as a standard ISO shipping container, made of 16 gauge COR-TEN weathering steel, built to hold sixty-seven thousand pounds and be stacked nine containers high. But these containers aren’t built specifically for MSSI; they’re built to be packed full of TVs, Blu-Ray players, or whatever else is being shipped to the US. After being unloaded of its goods, the containers are usually stacked in a port or a lot and left unused.

Unused, but not useless. MSSI’s business is built on reusing these shipping containers to manufacture the MAC Portal and other security products. They take the container, cut holes in it, install full-height turnstiles, motion sensors and state-of-the-art client-specified biometric access control technology. With the invention of the MAC Portal, the box nobody wanted is transformed into a high-tech gateway that is also capable of generating mustering reports, tracking worker time, preventing tool theft and even issuing payroll records.The MAC Portal installs quickly and easily, and because its shape is a standard container size, MSSI can get the MAC Portal anywhere a semi-truck or a cargo ship can go. It’s a fence-line ready guardhouse that is far more cost-effective than a traditional “stick-built” structure.
