CASE STUDY
Grade A Office: Lobby Speed Gates, Self-Service Visitor Registration and Lift Control
Staff pass the gates with cards or phones, visitors self-register and receive QR codes, and lifts only stop at authorised floors.
Grade A office building in Kowloon (client name withheld under confidentiality arrangement)
Background
The lobby saw long queues at the gates during morning peaks, and visitors had to be registered manually at reception, often blocking the entrance. The owner wanted to improve both image and efficiency while strengthening floor control, so visitors could not wander onto office floors.
Design
Six speed gate lanes were installed, two of them wide lanes for wheelchairs, luggage and bulky items. Staff can use contactless cards or mobile QR codes. Visitors scan their identity documents, take a photo and select their host at a self-service kiosk; the system notifies the host to confirm, then issues a one-time QR code. Floor control was added at the lift lobby, so only authorised floors can be selected.
Challenges
The lobby has a full glass curtain wall with severe backlighting during the day, making QR code scanning unstable. We fitted sun hoods and supplementary lighting around the scan windows and adjusted the camera angle downward. A staffed lane was retained so that reception can handle visitors who cannot be verified, keeping queues moving.
Result
Gate throughput at peak hours improved markedly, visitor records are now electronic, and the owner can export reports by floor and time period. Fire alarm integration was field-tested: on alarm, all gates unlock and remain open. The works were carried out over a weekend, and business resumed as usual on Monday.
