Upgrading Access Control in a Live Critical Healthcare Environment

A major hospital in the West Midlands required a full modernisation of its access control infrastructure – a demanding project made more complex by the need to upgrade a live system in a critical, round-the-clock environment with multiple departments and stakeholders.

The Challenge

The hospital had relied on our original Janus access control system that had delivered many years of dependable service. However, the solution had reached a critical point:

  • The operating system required to run the platform had reached end of life, leaving the site exposed to security and compliance risks
  • Ageing processors were limiting system performance and responsiveness
  • The existing infrastructure was unable to support modern, higher-security credentials or mobile access technologies
  • Upgrading a fully live system in a 24/7/365 critical healthcare environment, with numerous departments and stakeholders, demanded careful planning and minimal disruption

The Solution

The hospital selected Hall & Kay, working in partnership with Grosvenor Technology, to deliver a full migration to the JanusC4 platform. Hall and Kay were chosen for their extensive experience delivering access control projects in complex, operational environments. The solution included:

  • A complete upgrade from the legacy Janus system to the modern JanusC4 platform
  • Careful, phased delivery designed to maintain continuous operation throughout the project
  • Coordination across multiple departments and stakeholder groups within a working hospital
  • Future-proofing for higher-security credentials, including mobile access passes

The Results and Benefits

Hall & Kay delivered a turnkey solution from design conception through to final handover and end user training, ensuring zero disruption to the hospital’s critical operations. Key outcomes included:

  • Eliminated compliance risk: Removal of end-of-life OS dependency, bringing the site back into a supported, secure environment
  • Improved performance: Modern hardware replaced ageing processors, delivering faster, more reliable system responses
  • Future-ready infrastructure: The JanusC4 platform positions the hospital to adopt higher-security credentials and mobile passes as requirements evolve
  • Seamless delivery: The upgrade was completed within a live, 24/7 critical environment with no impact on hospital operations

Upgrading Access Control in Critical Environments

Healthcare facilities present some of the most demanding conditions for access control upgrades. Continuous operation, complex stakeholder landscapes and zero tolerance for disruption. This project demonstrates how the right partnership can:

  • Modernise without disruption: Delivering a full system upgrade in a live critical environment
  • Eliminate legacy risk: Removing dependence on unsupported platforms before they become a liability
  • Invest in the future: Deploying scalable technology that grows with the organisation’s security needs
