Replacing legacy card access with ZKTeco face recognition at a technology company's Singapore HQ - and demonstrating how a single face scan can trigger building automation, time & attendance, and payroll systems simultaneously.
Mitsubishi Elevator (Singapore) Pte. Ltd. is the sole agent and distributor of Mitsubishi elevators, escalators, and moving walks in Singapore, operating from their own 5-storey headquarters at 11 Kaki Bukit Crescent, Kaki Bukit Techpark 1. Established in 1972 and a market leader in vertical transportation, MESP holds strategic alliances with the Institute of Technical Education and the Building & Construction Authority. As a corporate partner of ZKTeco, MESP turned to Securevision - ZKTeco's preferred integrator - when they decided to upgrade their building's legacy card access system and demonstrate the capabilities of modern integrated security to their own clients and stakeholders.

Mitsubishi Elevator Singapore's existing card access system had reached the natural end of its useful life. Card-based credentials offer basic entry management but no intelligence - they cannot distinguish between users, cannot adapt to time of day or user type, and produce no data that other building systems can act on. For a company that is itself in the business of intelligent building infrastructure, this was a gap worth closing.
The upgrade brief went beyond simply replacing the credential type. MESP wanted to demonstrate - to their own staff, to their clients, and to the market - how modern access control can function as a trigger for broader building automation. The specific use case was a VIP scenario: when a designated senior staff member scans their face at the lift lobby, the Building Management System should automatically turn on the lights and air conditioning for their office before they arrive. This required not just a new access system but a reliable integration between ZKTeco and the Mitsubishi BMS - a proof of concept with real operational value.
A further requirement was integration with time & attendance and payroll. Every entry event from the face recognition terminals needed to feed automatically into the time & attendance system, which in turn feeds the payroll platform - eliminating manual timesheet processing.
| Operational Area | Before | Securevision Upgrade |
|---|---|---|
| Credential type | Card-based - no biometric verification | Face recognition - contactless, spoofing-resistant |
| BMS integration | None - access and building automation operated independently | Live integration: face scan triggers BMS to activate office lighting and aircon |
| Time & attendance | Manual or separate card-swipe system | Automatic: every face scan generates a verified time & attendance record |
| Payroll link | Manual data entry from time records | Automated: time & attendance data feeds directly to payroll platform via middleware |
| VIP automation | Not possible with card system | Configurable per user - VIP designation triggers customised building response |
| Audit trail | Basic card entry log | Biometric-verified entry record linked to time, attendance, and building event data |
The options ranged from a simple like-for-like card replacement to a fully integrated deployment. The card replacement would have solved the credential lifecycle problem but left the BMS, time & attendance, and payroll systems as separate silos. MESP wanted the upgrade to serve a broader purpose - as a working demonstration of integration capability for their own clients who operate intelligent buildings.
Securevision and ZKTeco jointly designed a middleware layer that positions the face recognition terminal as the trigger point for three downstream systems: the Mitsubishi BMS (office environment automation), the time & attendance platform (verified entry records), and the payroll system (automated time data). A single face scan at the lift lobby initiates all three - with no additional staff action required and no manual data entry at any point.
Outcome: The deployment served both as a functional upgrade to MESP's own building security and as a live, working POC that demonstrates intelligent building integration to prospective clients visiting the HQ.
Securevision approached the Mitsubishi Elevator project as two parallel workstreams: the access control replacement, and the integration architecture. Both needed to be complete before any of the demonstration capability could be shown.
Audited the existing card access infrastructure, mapped all entry points, and identified integration requirements for the BMS, time & attendance, and payroll platforms. Defined the VIP user flow for the POC scenario.
Installed ZKTeco face recognition terminals at lift lobbies and designated access points. Enrolled all staff credentials. Configured access schedules, user groups, and VIP designation flags.
Securevision and ZKTeco jointly built the middleware connecting ZKTeco to the Mitsubishi BMS and to the time & attendance / payroll platform. Defined event triggers, data formats, and failsafe behaviour for each integration point.
Configured the VIP scenario end-to-end: face scan at lift lobby → BMS trigger → office lighting and aircon activated. Verified the time & attendance feed and payroll data pipeline. Conducted live demonstration with MESP stakeholders.
The project was completed to a working demonstration standard - not just a functional access upgrade, but a live proof that the integration architecture works exactly as specified.
ZKTeco face recognition at the access layer; custom middleware connecting to BMS, time & attendance, and payroll downstream.
Contactless face recognition terminals replace the legacy card system at lift lobbies and access points across the HQ. Biometric verification means credentials cannot be shared or forgotten.
Entry Access Control →When a VIP-designated user scans at the lift lobby, the middleware sends a trigger to the Mitsubishi Building Management System, which activates the office lighting and air conditioning before the user reaches their floor. Demonstrates intelligent building response from a single access event.
Platform & Management →Every verified face scan generates a time & attendance record. The middleware feeds this data to the payroll platform automatically - eliminating manual timesheet entry and providing an auditable, biometric-verified record of all attendance.
Platform & Management →ZKTeco face recognition terminals across lift lobbies and access points, with Securevision-built middleware connecting to the Mitsubishi BMS, time & attendance, and payroll platforms.
Terminals: ZKTeco face recognition terminals at lift lobbies and designated access points
Platform: ZKTeco access management software
BMS integration: Event trigger sent to Mitsubishi BMS on VIP face scan
Time & attendance: Every entry event creates a verified attendance record
Payroll link: Automated data pipeline from time & attendance to payroll
Contactless face recognition replaces the existing card system across the HQ. No more lost cards, no credential sharing, no manual card management.
The VIP smart-office scenario works as specified: a single face scan at the lift lobby triggers the BMS to activate lighting and aircon before the user arrives at their office.
Every entry event creates a biometric-verified attendance record, fed automatically to the time & attendance and payroll platforms. Manual timesheet processing eliminated.
The integrated system serves as a working proof of concept for MESP clients visiting the HQ - demonstrating how face recognition, building automation, and HR systems can operate as a single connected workflow.
The middleware design is not specific to this building. The same pattern - access event as trigger for downstream systems - can be replicated across other MESP clients' facilities.
Most access control installations are designed to answer one question: is this person allowed through this door? The Mitsubishi Elevator project was designed to answer three more: did this person arrive on time, should the building prepare for them, and what does the payroll system need to know? When you treat an access event as a structured data point rather than a door decision, it becomes the trigger for processes that previously required manual effort at every step. This is the case we made to MESP, and it is also the case their building now makes to every client who visits.
Every project Securevision delivers draws on multiple systems working together - cameras, access control, intercoms, vehicle management, network infrastructure, and platform software. The cards below show the full range of systems we design and install. Each one links to a deeper explanation of how it works, when it is needed, and what to look for when specifying it.
Whether you need biometric access, BMS integration, or a time & attendance link, we can design a connected workflow tailored to your facility.
