Fire and smoke detection for high-rise buildings
Fire and smoke detection for high-rise buildings is visual detection of flame and smoke on the cameras a tower already has in its corridors, lobbies, stairs, parking levels and plant rooms, raised as a critical alert with a clip to the person on duty, as an early-warning layer beside the code-required fire alarm system and never instead of it. The alarm is certified, required and stays. What the cameras add is a picture: where the smoke is, on which floor, before anyone has to go and look.
- Visual flame and smoke on the cameras already installed
- Beside the fire alarm, never instead of it
- A clip on the duty desk that names the floor
The alarm says a floor. The camera says where.
A high-rise fire alarm does its job: it sounds, it reports a zone, and the building begins to move. What it cannot do is show the front desk what is burning, whether the haze in the stairwell is from a fire or a cigarette, or whether the corridor on the twelfth floor is clear. Somebody has to go and look, and in a tower that walk takes minutes.
The corridors, lobbies, parking levels and plant rooms already have cameras, installed for security and recording to a box that is checked after the event. None of them is watching for a fire, and none of them tells anyone when it sees one.
“Dock door left unsecured after delivery — confirm and lock.”
Unacknowledged alerts escalate to the backup contact after the configured window.
An earlier picture, on the cameras the tower already has
Fire and smoke detection watches each camera's live feed for the visual signatures of flame and smoke and raises a critical alert with a clip and a confidence score when a match passes the threshold set for that camera.
- It runs on the standard corridor, lobby and garage cameras already in place; no thermal hardware is involved.
- The alert names the camera, so the desk knows the floor and the spot before anyone climbs a stair.
- Steam from a laundry vent, exhaust in a garage and dust from works are the known confounders, and the threshold is set per camera for that reason.
- A person verifies from the clip; the alarm, the evacuation and the call to the fire service follow the building's fire plan unchanged.
A patrol round covers the part that neither the alarm nor the detection does.
- At each stop it asks whether the stair door is closed, whether the landing and the corridor are clear, whether anything is stored in the stair and whether smoke is visible, and records the answer with the frame.
- On an automated round the AI raises a critical notification for a risk it sees that the checklist did not ask about.
- Camera tampering detection catches a corridor camera that has gone blind, which in a tower is a floor nobody is watching.
Fire and smoke detection
Visual flame and smoke in a corridor, a stair, a lobby or a parking level, raised as a critical alert with a clip.
DetectionCamera tampering detection
A covered, turned or failed camera on a floor, raised the same day rather than found after the event.
DetectionAbandoned object detection
A bicycle, a stroller or a delivery left in an exit stair or a corridor past a dwell time you set.
DetectionZone intrusion detection
A person in a plant room, a refuse room or on the roof, notified in the hours you set.

- Stair landing clearNot compliant
- No smoke visibleCompliant
- Corridor camera unobstructedCompliant
A failed item is resolved as Fixed or Pending before the round can close.
What a high-rise round checks
A high-rise sequence walks the stairs, the corridors, the lobby, the parking levels and the plant rooms in floor order, and its checklist is what a fire officer would want to find on every level.
- The stair door is closed on its closer.
- The landing and the corridor are clear.
- Nothing is stored in the stair or against the riser cupboard.
- No smoke is visible.
Run it at closing and through the night. Each round's report is the record that every stair was clear at that time, with the frame, and a stack of them is what the annual inspection and the insurer ask for. The same detection in a warehouse or a plant is covered under fire and smoke monitoring.
A check found Not Compliant captures a snapshot and messages the guard designated for that camera; on a manual round the operator chooses to send it, on an automated round it goes on its own. The item stays Pending until it is marked Fixed, which captures the after frame, and the report shows both.
Why it matters in a tower
Published figures from the National Fire Protection Association and the US Fire Administration on high-rise and residential fires.
- 14,830
- reported structure fires in high-rise buildings each year in the United States in 2019 to 2023, causing an average of 33 civilian deaths, 439 civilian injuries and $203 million in direct property damage per year.
- Source: NFPA, High-Rise Building Fires (October 2025)
- 1,588
- fires each year in high-rise multifamily dwellings with seven or more units in 2019 to 2023, with 14 civilian deaths and 152 civilian injuries a year. A kitchen was the area of origin in 59 percent of them, and bedroom fires accounted for 44 percent of the deaths.

- 45%
- of fatal fires in residential buildings in 2018 to 2020 happened between 11 p.m. and 7 a.m., and being asleep was the leading human factor contributing to ignition, reported in 41 percent of them.

- 80%
- of fatal fires in residential buildings in 2018 to 2020 extended beyond the room of origin, and smoke alarms were not present in 24 percent of fatal fires in occupied residential buildings.

What it will not do
In a tower the limits are the alarm system's job, the closed door and the camera's view.
- It will not replace or connect to the fire alarm, the sprinklers, the smoke control or the evacuation plan, and it is not certified as a life-safety system; the code-required system stays and runs as before.
- It will not see a fire inside an apartment or an office behind a closed door; it sees the corridors, stairs, lobbies, parking levels and plant rooms where the cameras are.
- It will not see through a corridor once smoke has filled it; the value is in the first minutes, not the last.
- It will not call the fire service or start the evacuation; it tells the person you designate, with a clip, and the fire plan does the rest.
We do not publish detection rates, lead times over the building's sensors or false-alarm figures, because they depend on your cameras and your building. The trust page sets out the policy.
