Walmek — Access Control
Electronic access control for hospitality — hardware, firmware and software all engineered in-house, including ultra-low-power battery devices.
Electronic access control for hospitality — hardware, firmware and software all engineered in-house, including ultra-low-power battery devices.
A full-stack engineering project Finite Software Systems delivered end to end — hardware, firmware and software, all developed in-house. It is a cloud-managed electronic access-control system for hospitality, administering battery-powered door locks across whole property portfolios from one web platform.
The defining challenge was energy. The field devices run for years on battery, so FSS engineered the electronics and embedded firmware for extremely low power draw — a heavily optimised, very specific design where every microamp matters and keeping the devices both frugal and reliably responsive is genuinely hard to achieve. That low-energy hardware and firmware work is the part of the project we are proudest of.
Around the devices sits a Laravel/PHP application on MariaDB that manages properties, devices and credentials and communicates with the fleet over web-application messaging protocols. It is an IoT system in the full sense — custom low-power hardware in the field, optimised firmware on the device, and a cloud application orchestrating it all — designed, built and maintained by one team.
