Fire detection cameras for warehouses

Last updated 30 October 2026. Warehouses are hard places to protect from fire. They are big, tall and full of cardboard, plastic wrap and wooden pallets. Many run through the night with a handful of people, or stand empty from Friday evening to Monday morning. A fire alarm will sound inside the building, but if nobody is there to hear it, or the smoke takes minutes to reach a detector under a 15-metre roof, the fire has a head start. This page explains how AI fire detection cameras work on warehouse CCTV, where they help most, what they do not do, and how to plan them around your fire risk assessment.

What is a warehouse fire detection camera?

A fire detection camera is a CCTV camera whose video is checked by software trained to recognise smoke and flame. In most warehouses that means the cameras you already have. Woodcock AI connects to existing IP cameras over ONVIF or RTSP, runs detection on an edge server on site or on a cloud server, and watches every frame for the shape, movement and colour of smoke and fire. When it finds them inside a zone you have drawn, it sends an alert to the app with a short clip, and by email.

That is different from a traditional fire alarm. Smoke detectors and heat detectors work when smoke particles or heat reach the device itself, which is usually on the ceiling. A camera works at a distance. It can see smoke forming at the base of a pallet stack 30 metres away, or rising from the top of a racking bay, without waiting for it to travel anywhere. For the technical detail, see our guide to video smoke detection on existing CCTV and the main smoke and fire detection camera page.

Three things make camera detection practical in a warehouse:

• Polygon detection zones. You draw the exact area each camera should watch: the top of a racking run, a pallet pad, a dock door line. Detection only reports inside those shapes, and the alert names the zone. See polygon detection zones.
• Self-learning. Every warehouse has its own lighting, dust, steam from wash-downs and reflections off shrink-wrap. The system learns what is normal for each camera, which cuts the false alerts that make people ignore notifications.
• The clip. An alert that arrives with a few seconds of video lets a keyholder or monitoring centre see what is happening in moments, rather than driving to site to check a panel.

Why are warehouse fires so hard to detect early?

Fire and rescue services in England attended 14,167 fires in non-domestic buildings (the “other buildings” category, which includes warehouses, factories and shops) in the year ending September 2025, up 7.8% on the year before, according to official fire statistics on GOV.UK. Warehouses make up only part of that figure, but they account for many of the largest and most expensive fires, for three main reasons.

The fuel load is high and it is stacked. The GOV.UK guide Fire safety risk assessment: factories and warehouses warns that in high stacked storage, flames can spread rapidly and vertically to the top of the racking, then laterally to all levels. The gaps between pallets act as chimneys. Cardboard, plastic packaging and wooden pallets all burn quickly.

The roof is a long way up. Smoke has to rise and cool on the way. On a hot day, or under an uninsulated roof, a warm layer of air can form just below the ceiling. Research by the Fire Industry Association looked at how smoke can stall below that layer, so it spreads sideways under the warm air and never reaches ceiling detectors in quantity. BS 5839-1 already allows extra beam detectors at lower levels in tall spaces for this reason, but they need careful design and many more devices.

Hot roof layer

Nobody is there. Many warehouse fires start at night or at weekends, when the building is shut or lightly staffed. A sounder in an empty building does not call anybody. Unless the fire alarm is linked to a monitoring centre and someone acts on the signal, the first call to the fire service may come from a passer-by who sees flames through the roof.

What do recent warehouse fires tell us?

London Fire Brigade incident reports from 2026 show how much resource a warehouse fire takes, and how many happen out of hours:

• On 15 October 2026, 12 fire engines and around 80 firefighters were called to an industrial warehouse on Water Road, Wembley. The first call came in at 02:18. Part of the ground floor was destroyed, and the fire was under control by 04:07.
• On 6 September 2026, 10 fire engines and around 70 firefighters attended a two-storey warehouse on Alperton Lane, Wembley. The brigade took the first call at 14:47; half of the ground floor was destroyed, and the fire was under control at 18:24.
• On 11 June 2026, 25 fire engines and around 150 firefighters fought a fire at a two-storey warehouse on Oxgate Lane, Brent. The brigade took more than 85 calls from 21:14, around 70 residents were evacuated as a precaution, and the fire was under control at 05:02 the next morning.

Outside London, the BBC reported that a warehouse in Harwich, Essex, was thought to have been burning from about 01:00 on 16 August 2026 before the fire service was called at 03:36. More than 30 firefighters attended. The building, thought to hold stocks of cardboard boxes, later collapsed.

Two-hour gap

Not every fire ends this way. The British Automatic Fire Sprinkler Association described a fire at a Northamptonshire distribution warehouse on 23 July 2026, reported at 21:27, where sprinklers controlled a fire on a fifth-floor mezzanine before crews arrived. BAFSA uses the case to call for sprinklers in more warehouses, citing NFCC research that 4,000 m² is the limit for effective firefighter rescue, and arguing that the current 20,000 m² threshold for warehouses should be lowered. Sprinklers and early detection work together: one controls the fire, the other gets people moving.

Does a fire detection camera replace our fire alarm?

No. Your fire alarm system, designed and maintained to BS 5839-1, remains the legal and insurance baseline. It raises the alarm in the building, it is what your fire risk assessment relies on for evacuation, and it may be linked to an alarm receiving centre. Camera detection adds a different kind of layer:

• It looks at the space, not just the ceiling, so it can see smoke near where it forms.
• It covers outside areas, such as yards, pallet stores and skips, where most fire alarms have no detectors at all.
• It sends an alert with a clip to people who are not in the building, and can route it to a monitoring centre.
• It gives the person who receives the alert enough information to act: which camera, which zone, and what it looks like.

Layered protection

Talk to your fire risk assessor and your insurer before you change anything about your fire strategy. Our guide to what insurers expect from fire detection covers the questions they tend to ask.

Where do fire detection cameras help most in a warehouse?

Start with the places your fire risk assessment already flags, then look at where a fire could grow unseen. Pick an area below to see what to watch for and how cameras are usually set up.

Two more areas deserve their own mention:

Battery charging areas. Charging lithium-ion and lead-acid batteries for handling equipment, scanners and tools is one of the main fire risks in a modern warehouse. A camera with a clear view of the charging bay, with a zone drawn round the chargers, can report smoke or flame at any hour. Our guide to lithium-ion battery storage and charging fire safety covers spacing, layout and quarantine.

Hot work. Welding, cutting and grinding during maintenance or fit-outs is a classic cause of fires that start hours after the work stops. Camera detection can watch the area through the fire-watch period and beyond. See our guide to hot works fire risk.

How do cameras help with outside storage and arson?

Many warehouse fires start outside. The GOV.UK guide for factories and warehouses tells businesses to keep goods, pallets and vehicles in designated areas away from the building, exits, windows and the boundary fence. Wheeled bins should be secured in a compound so they cannot be moved next to the building and set alight, and skips should never stand against a wall. Discarded packaging and piles of wooden pallets, the guide says, introduce severe fire hazards.

For arson, the same guide recommends lighting the outside of the building, securing the perimeter, removing rubbish regularly and encouraging staff to report people acting suspiciously. Cameras support each of those measures:

• Smoke and flame zones on the pallet store, bin compound and skips report a fire outside before it reaches the cladding.
• Line-crossing detection on the fence line, scheduled for out-of-hours, reports someone climbing in.
• Intrusion detection in the yard reports a person in a zone where nobody should be at night.

Site plan

If your yard holds trailers overnight, park them squarely in marked bays, away from the building and each other where space allows, and include them in the camera plan. A fire in a curtain-sided trailer can spread to the next one, and to a building, quickly.

How do you plan fire detection cameras for a warehouse?

A good camera plan starts with your fire risk assessment and the building layout, not with a camera catalogue. In a site assessment we usually work through these steps:

1. List the areas. Racking aisles, docks, charging areas, baler, pallet store, mezzanine, yard. Each becomes a named zone, so the alert tells you exactly where the problem is.
2. Check the cameras you have. Many warehouses already have good aisle and yard coverage. We check each camera’s view, resolution, night performance and stream. Hikvision and other ONVIF cameras usually connect without changes; see our page on Hikvision smoke detection cameras.
3. Fill the gaps. Typical gaps are the top of racking runs, charging bays, the back of the baler, and outside stores. A camera looking along an aisle sees much more of the racking than one looking across it.
4. Light it. Smoke detection needs to see the smoke. Keep some lighting on at night or use cameras with good infrared or colour night vision, and avoid pointing cameras straight into floodlights.
5. Draw the zones. Polygon zones follow the shape of each area, such as the top two beam levels of a run, or the concrete pad of a pallet store, so the system ignores the aisle floor below or the road beyond the fence.
6. Decide who gets what. Agree which keyholders receive alerts for which zones, at which times, and whether alerts also go to a monitoring centre.

Zone plan

What happens when a camera detects smoke at night?

Speed matters, but so does getting the alert to someone who can act. When Woodcock AI detects smoke or flame in a zone, it sends an alert to the app with the clip, and an email. The person receiving it sees the camera name, the zone and a few seconds of video, so they can tell straight away whether it is a real fire, steam from a wash-down or a cloud of dust from a sweeper.

Two optional add-ons help warehouses that run unstaffed shifts:

• Monitoring centre (ARC). Alerts are passed to an alarm receiving centre whose operators watch the clip and follow your response plan.
• Call alerts. An automated call to a keyholder, for people who may sleep through a notification.

Alert flow

Your response plan should say what happens next: who calls the fire service, who meets them, where the site plans and keys are, and how to isolate power to charging areas. If you are not sure, it is safer to call 999 and let the fire service decide. Do not send staff into a building to check on a fire.

Can the same cameras do more than fire detection?

Yes. The same cameras and the same platform can run other detections in other zones or at other times of day. Warehouses commonly add:

• Intrusion and line-crossing for the yard, fence line and dock doors after hours.
• PPE (hard hats & hi-vis) detection in areas where they are required, such as the yard and the dock apron.
• Vehicle detection for vehicles entering the yard or parking where they should not after hours.

Our warehousing and logistics page covers those uses in more detail.

What are the limits of camera fire detection?

Camera detection is a powerful extra layer, but it has limits, and a good supplier will tell you about them up front:

• It needs line of sight. A camera cannot see inside a closed cabinet, behind a full pallet or inside a trailer. Smoke usually escapes and becomes visible, but placement matters.
• It needs light. In total darkness with no infrared, there is nothing to see. Most warehouse cameras have night vision, and many sites keep some lighting on.
• Obstructions change. Stock moves. A view that is clear on Monday may be blocked by a full bay on Friday. Review camera views when layouts change.
• It is not a certified fire alarm. It does not replace detectors, call points or sounders, and it is not a substitute for a fire risk assessment.

Within those limits, cameras are well suited to the parts of a warehouse where ceiling detectors struggle or are absent: tall racking, mezzanines, open docks and everything outside.

A quick checklist before you start

• Is every storage and charging area named in your fire risk assessment?
• Are pallets, skips, bins and trailers kept away from the walls, exits and fence?
• Can a camera see the top of each racking run, the charging bay and each outside store?
• Is there enough light or infrared at night?
• Who gets an alert at 3am on a Sunday, and do they know what to do?
• Have you told your insurer about your detection and storage arrangements?
