Workplace & Office Buildings

The politest security failure there is.

Entrance control for offices, headquarters and multi-tenant buildings — where the threat is not a forced door but a held one, and the lobby has to look like a lobby.

The Challenges

What a lobby is actually up against.

Offices rarely fail at the door through force. They fail through courtesy, through visitors, and through nobody knowing who is still upstairs.

01

Somebody holds the door

The credential presented was genuine. The person who followed had none. Every card reader in the building is satisfied, and someone unaccounted for is now on the third floor. Politeness is the attack surface.

02

The visitor card that never came back

Issued at the desk, signed for, and gone. Somewhere in a drawer, a coat pocket or a car. A physical pass that outlives the visit is a credential with no owner and no expiry.

03

Nine o'clock

Most of the day's traffic arrives inside forty minutes. A gate that hesitates turns a lobby into a queue, and the queue is the first thing a client sees on the way to a meeting.

04

Four tenants, one entrance

Different companies, different floors, different hours, different contracts. The building operator has one lobby to give them, and each tenant expects their own rules to hold at it.

05

The timesheet nobody trusts

Attendance recorded on an honour system, or on a separate terminal that people forget. The entrance already knows exactly when everyone arrived; the information is simply thrown away.

06

The roll call at the car park

The alarm sounds, the building empties, and someone at the assembly point has a clipboard and a guess. Without a counted exit, the difference between everyone out and someone missing is an assumption.

The Response

Four things the lobby has to get right.

WP-01 · ANTI-TAILGATING / 5:4 landscape Photograph looking down a corporate speed gate lane from a low camera position at about hip height. Two mirror-polished stainless steel pedestals frame the shot, their inner faces carrying a neat vertical column of small dark infrared sensor windows, several glowing faint red. A thin array of red infrared beams crosses the lane at several heights in slightly hazy air, subtle and technical rather than dramatic. One professional in a dark coat has passed through and the glass wings are already closing behind them; a second figure waits behind the closed wing, visible only from the waist down. Dark polished stone floor faintly reflecting the red beams and the wing edges. Background is a refined corporate lobby, entirely out of focus, with cool blue window light. 35mm lens perspective, shallow depth of field, low ambient light with red and green accents. Precise, matter-of-fact, unconfrontational. No text, no logos, no faces.
01 — Tailgating

One authorisation, one passage

Infrared sensor windows run the full height of each inner face and read presence across the whole lane rather than at a single beam. A second body following the first is detected, the wings close on the entry, and the attempt is logged rather than argued about.

This is the part a card reader cannot do. The credential was valid; the problem is that two people used it.

WP-02 · VISITOR PASS / 5:4 landscape Close product photograph of a visitor presenting a phone to a reader panel set into the lid of a mirror-polished speed gate in a corporate lobby. The phone screen displays an abstract generic QR-style square pattern that lights the surrounding metal; the reader's small screen glows warm white with a simple check-mark and a soft green indicator above it. Only a hand and lower forearm in a suit cuff are visible, cropped and softly out of focus at the frame edge. Behind, the lobby dissolves into cool blue window light and dark stone, entirely out of focus, with one warm highlight. Shot at 85mm macro perspective, very shallow depth of field with only the reader critically sharp. Lit principally by the two screens plus one soft key from above left, a thin champagne-gold reflection along the polished edge. Effortless, modern, discreet. No readable text, no logos, no branding, no face.
02 — Visitors

A pass that expires by itself

A visitor credential is a QR code issued for a defined window and read from a phone screen or from paper at the same lane as staff. Nothing is handed over, so nothing has to be recovered.

Contractors, couriers and interview candidates all pass through the same lane under the same rules, and the record of who was in the building is created at the door rather than reconstructed from a signing-in book.

WP-03 · MORNING PEAK / 5:4 landscape Architectural photograph of a corporate lobby during the morning arrival peak, shot from a slightly elevated position at chest height. Four speed gate lanes in mirror-polished steel run across the frame, glass wings opening and closing at different stages, small green indicators lit. A steady flow of professionals moves through all four lanes rendered as soft motion blur so no individual is readable, giving a sense of continuous unhurried movement rather than crowding. Cool morning daylight pours through a double-height glazed façade behind, throwing long soft reflections across a dark polished stone floor. Wide composition, 28mm lens perspective, bright cool light with clean shadows. Orderly, efficient, calm — the image should read as flow, not congestion. No text, no logos, no signage, no faces toward camera.
03 — Throughput

Peak without a queue

The published open cycle is 0.7 seconds, adjustable, giving up to 50 people per minute per lane, as published by the manufacturer in September 2025. Two lanes clear most single-tenant arrivals; four handle a headquarters.

Throughput and security are usually traded against one another. A fast cycle with full-height infrared sensing is how you avoid making that trade at the door.

WP-04 · FAIL-OPEN / 5:4 landscape Architectural photograph of a corporate lobby speed gate lane in its fully open, free-passage state during an evacuation condition. The glass wings of two mirror-polished pedestals are swung completely flat against their housings, leaving the lane entirely clear across a dark polished stone floor. A soft green indicator glows on each lid, and above the corridor beyond, a plain illuminated green emergency light casts a gentle wash down a dark wall — shown only as a simple glowing rectangle with no readable text or pictogram. The lobby is empty and dim, lit only by low ambient light and the blue of the glazed façade. Symmetrical straight-on composition looking down the centre of the clear lane, camera at eye level, 35mm lens perspective, moderate depth of field so the open passage reads all the way back. Green safety glow dominant against cool blue neutrals. Calm, safe, unmistakably open. No text, no readable signage, no pictograms, no logos, no people.
04 — Evacuation

Open, and counted

On power loss or an alarm the wings release to free passage and stay there, as EN 17352 requires of motorised pedestrian barriers on escape routes.

Because every lane is bi-directional, the exit is a recorded event rather than an absence. The last count of who had entered and not left is available to whoever is holding the list at the assembly point.

Included in a Turnkey Delivery

One lobby, several sets of rules.

In a multi-tenant building the hardware is shared and the policy is not. The entitlement logic behind the gate is what lets one row of lanes serve four different companies without four different lobbies — configured and supported by Keyable Europe on a turnkey delivery.

  • Per-tenant entitlements on shared lanes
  • Time-bounded visitor and contractor passes
  • Attendance recorded at the point of entry
  • Live occupancy for roll call and floor loading
  • Cached entitlements when the network drops
  • Fail-open on power loss, always

WP-TECH / portrait 4:5 Elegant dark-mode macro photograph in portrait orientation of a reader panel set flush into the mirror-polished lid of a corporate speed gate. The small screen glows warm white showing a single simple check-mark symbol, its light catching the polished metal around it and reflecting as a soft vertical streak. The polished surface reflects a blurred suggestion of a dark lobby and one distant warm light. Deep near-black background entirely out of focus. Close three-quarter macro, 85mm lens perspective, extremely shallow depth of field with only the screen and nearest metal edge critically sharp. Single soft key light from the upper left plus the glow of the screen, with a thin champagne-gold reflection tracing the edge. Precise, premium, technological, calm. No readable text beyond the check-mark, no logos, no branding, no hands, no face.
Recommended

Three configurations that suit this sector.

Chosen for what an office lobby actually demands: presence at the front, throughput in the middle, and a taller barrier where the floor is restricted.

WP-CASE / 16:11 landscape Wide architectural establishing photograph of a multi-tenant office building lobby in the early evening, with no people present. Four speed gates in mirror-polished stainless steel with frameless glass wings stand in a precise row across the frame, all closed and ready with soft green indicators lit, their reflections stretching across a dark polished stone floor. The lobby is generous and restrained: a double-height glazed façade behind showing deep blue dusk and softly blurred city lights, a long minimal reception desk in dark stone to one side, unattended, a single tall planting in a dark vessel, one vertical strip of warm light washing the far wall. Beyond the gates, a lift lobby is visible as a dim recess with faint warm light. Generous headroom, camera at eye level, 28mm lens perspective, shallow depth of field. Cool blue palette with warm gold accents. Calm, empty, ordered, expensive. No text, no logos, no signage, no people.
Workplace

Four lanes, four tenants

A headquarters building shared by four companies: one row of speed gate lanes on the main lobby, per-tenant entitlements applied at the same hardware, visitor passes issued as time-bounded QR codes, and attendance recorded at the point of entry rather than on a separate terminal.

Because every lane counts in both directions, the building operator has a live occupancy figure for floor loading and for the roll call, without asking anyone to keep a list.

Common Questions

Answers, briefly.

What is tailgating in access control?

Tailgating is a second person entering on someone else's authorisation, usually by following them through a gate that is already open. It is the most common way a controlled building is entered without a credential, and it defeats card readers entirely, because the credential presented was genuine.

How do speed gates stop tailgating?

A column of infrared sensors reads the full height of the lane rather than a single beam, so a second body following the first is detected and the wings close on the entry. One authorisation produces exactly one passage, and the attempt is logged.

How fast do office speed gates need to be?

Fast enough that the morning peak does not queue. Keyable speed gates open in 0.7 seconds, adjustable, giving up to 50 people per minute per lane, as published by the manufacturer in September 2025. Two lanes will clear most single-tenant office arrivals.

Can entrance gates handle visitors and contractors?

Yes. A visitor pass is a QR code issued for a defined window, read from a phone screen or from paper at the same lane as staff credentials. It expires by itself, so no card has to be recovered at the end of the day.

Can the entrance provide a fire roll call?

Yes, in part. Because every barrier is bi-directional, entries and exits are both recorded and the difference is a live figure for who is still inside. On an alarm the barriers release to free passage, as EN 17352 requires on escape routes, and the last recorded count supports the roll call at the assembly point.
