StoneCircle TerminalFOR THE GATE

The gate keeps working.
Even when the internet
does not.

StoneCircle Terminal puts access decisions on site. A resident can create a code without mobile data, the gate can verify it without the cloud, and the passage is saved until the connection returns. Your perimeter stays operational instead of becoming a queue.

No signal at the gate.
No disruption at the gate.

Stonecircle Terminal and Terminal Core keep the essential access path local. Guards get an immediate answer, connected barriers and turnstiles can still act, and the event record catches up automatically after reconnection.

  1. 01
    Keep the lane moving

    Authorised residents and guests do not wait for a network request.

  2. 02
    Keep guards in control

    The terminal gives a clear local grant or denial instead of asking staff to improvise.

  3. 03
    Keep the record intact

    Passages are held safely on site and retain the time they actually happened.

VS
Gate Terminal vs Terminal Core — which one does your gate need?

Gate Terminal is the guard-facing kiosk at a staffed gate — verify codes, log walk-ins, raise incidents. Terminal Core is the always-on controller that keeps access decisions local: it verifies offline, drives the barrier, and reconciles to the cloud when connectivity returns. Staffed main gate? Both. Unmanned or secondary entrance? Terminal Core can run it alone.

What does hardware cost?

Every estate's perimeter is different, so we quote after a free site assessment rather than publishing a misleading flat price. Two things are always true: hardware is a one-time capital cost — it never joins your monthly software fee — and you'll get a written, itemised quote before any commitment. Many estates phase installation across two or three budgets, starting with the gate.

Spreading the cost: many estates phase installation across budgets or align it with a special levy — we'll structure the quote to match how your estate funds capital projects.

The integration story

The hardware knows
what the software knows.

Most security firms install hardware and walk away. Stone Security wires its hardware into the same operating system your residents and FM use. One event, recorded in three places — at the gate, in the resident's app, and in the chairman's dashboard.

If the connection drops, the gate keeps deciding and recording locally. When it returns, Limestone reconciles the saved events into the same source of truth.

From site visit
to live perimeter
in 21 days.

We don't do shipping container hand-offs. Our team handles site assessment, install, commissioning, and the first 60 days of operation — including training your security personnel on the kiosk.

01 — DAY 1

Site assessment

Our engineer walks your perimeter with your FM and chairman. Marks placement for cameras, barriers, fence, panels. Estimate within 48 hours.

02 — WEEK 1–2

Build & install

Civil works (if needed), cabling, mounting, configuration. We pre-test everything in the workshop so on-site time is minimal.

03 — WEEK 3

Commission & train

Live commissioning with your FM. Your guards train on the kiosk. Your chairman gets a walkthrough of the dashboard. Sign-off only when it works.

04 — ONGOING

Operate & maintain

24-month hardware warranty. Quarterly preventive maintenance covers barrier mechanics and motors, camera alignment and storage health, UPS and power checks, and firmware updates. Hardware faults get a response SLA with a named technician your facility manager can call. After the warranty, an optional maintenance retainer continues coverage with priority response.
