Security and resilience
A well-engineered wired installation is straightforward to supervise end-to-end: power, data and tamper states are continuously monitored, and controllers can enforce advanced policies (anti-passback, door interlocks, multi-factor). The widely recognised BS EN 60839-11-1 standard sets minimum functionality and performance requirements for electronic access control systems and components—useful as a baseline when specifying platforms, regardless of cabling.
Modern wireless locks are also robust when deployed correctly, but they change the risk profile: radio links must be properly encrypted and key-managed; gateways need secure siting, patching and network segmentation; and battery health becomes a security dependency. NPSA’s guidance on electronic locks notes the importance of configuration governance and update processes (e.g., how policy updates are distributed to devices, especially those not permanently online). That operational discipline is part of security.
Fire and safe egress
Whatever you choose, security must never compromise safe escape. In the UK, electronically controlled doors on escape routes must release reliably under fire conditions and relevant faults. BS 7273-4:2015+A2:2023 clarifies the “critical signal path” between the fire alarm and door release devices and gives additional detail on acoustic and radio-actuated mechanisms—vital if you intend to deploy radio-linked release in certain categories. In practice, many sites retain hard-wired release on escape routes for determinism and to match the category of actuation required by the fire strategy. Build this behaviour into design, commissioning and routine tests.
Deployment speed and building constraints
Wired doors require pulling cable to each opening and providing power for locks. In new builds or refurbishments—with ceiling voids open and containment planned—that’s efficient and gives you excellent supervision. It’s also preferred where you need door interlocks, high throughput, or integration with lifts and turnstiles.
Wireless shines in retrofits and heritage buildings where chasing walls or installing containment would be costly, unsightly or impractical. Battery-powered locks can be fitted with minimal disruption and without visible cabling; a handful of discreet gateways can cover a floor or wing, depending on construction and radio conditions. You’ll still need to plan for gateway power and backbone connectivity, and you should model signal propagation carefully in dense or attenuating structures.
Performance and user experience
Day to day, users care about speed and consistency. Wired readers tend to feel instantaneous because door controllers make decisions locally with constant comms. Wireless locks can be near-instant too, but some architectures periodically synchronise access lists rather than query the server each time; this can introduce a short delay when credentials are first updated, mitigated by sensible sync intervals. Throughput matters at busy lobbies: we often recommend wired readers on main perimeters and wireless on internal offices or side rooms where traffic is lighter.
If you’re aiming for touch-free journeys (no keypad presses or handle touches), both approaches can support that with the right kit. For practical options and upgrade paths, see our overview of Hands-Free Access Control.
