Mercury Security, an HID brand and a longtime supplier of open-architecture access control hardware, has launched its Mercury S4 I/O Module family, a new generation of intelligent modules designed to help organizations expand and modernize physical access control systems built on existing Mercury infrastructure.
More Capacity, Built-In Cryptographic Headroom
According to Mercury, the S4 family delivers six times the memory and eight times the storage of prior-generation modules, along with support for post-quantum cryptography aimed at hardening access control communications against future cryptographic threats to critical infrastructure. The modules are built for forward and backward compatibility, letting integrators add doors, readers and other security devices to existing Mercury intelligent controllers without replacing them, while increasing door density and reducing the physical footprint of the resulting installation.
Responding to Longer Infrastructure Lifecycles
The company said its ongoing research into access control professionals’ priorities identified sustained emphasis on cybersecurity and data protection standards, alongside a need for hardware that supports both forward and backward compatibility as organizations plan access control investments over longer timeframes. The Mercury S4 I/O Modules are available now through Mercury’s OEM partner network, extending an open-architecture platform the company has developed since its founding in 1992.
