A New Standard in Fire Detection
Proven by performance. Now written into the code. Flir A-Series thermal
imaging cameras are UL 2684 Listed and prescriptive under NFPA 72:2025,
and the Flir A70 is the world's first listed thermal imaging fire detector:
specify it, permit it, and connect it to the panel like any other initiating device.
Engineered and manufactured by the global leader in infrared technologies. With UL 2684 listing, high-performance thermal imaging detection is now a prescriptive fire alarm initiating device.
Higher capacity, higher density, higher power. Modern facilities carry more fire risk in less space, with fewer people on the floor to see it coming.
Anything that can catch fire gives off heat first. Industry has relied on thermal imaging for decades to catch it early. Continuous monitoring makes that warning permanent, and UL 2684 listing makes it the core of a higher-performance safety strategy.
640 × 480 radiometric thermal imaging plus a 1280 × 960 visual camera for instant context at alarm
35 mK thermal sensitivity and ±2°C accuracy, calibrated at every pixel
On-camera alarm logic with up to 20 regions of interest: threshold, rate-of-rise, delta, and area-percentage triggers
Alarm, supervisory, and fault dry-contact outputs to the fire alarm control panel; Modbus TCP, MQTT, Ethernet/IP, and ONVIF for SCADA, BMS, and VMS
29°, 51°, and 95° lens options with 3 × 3 pixel detection distances to 125 m (410 ft)
Every fire starts as heat. Each conventional technology waits for a later signature: particles, visible smoke, flame, or heat at the ceiling. A thermal imaging fire detector measures the heat itself, before any of those exist.
Flir has designed and manufactured thermal imaging cameras for over five decades, supporting the professionals who keep industry safe and running. The same infrared technology now stands watch as a listed fire detector.
High ceilings, high airflow, dust, and outdoor exposure can challenge conventional spot smoke and heat detection. A thermal imaging fire detector measures temperature across the entire scene and alarms on developing heat, providing earlier warning before smoke or flame appears.
The camera alarms on its own. Software adds the viewing, evidence, and remote alerting each site needs.
Cloud-based monitoring
Cameras connect through the internet, a cellular router, or Starlink and send images rather than video, so remote and low-bandwidth sites get direct-to-alarm coverage without a network build-out. Adds user-defined alarm logic, AI that excludes vehicles so the earliest alarms are real, and alerts straight to a phone.

Video management system
Live thermal and visual video from every camera, recorded and retained for evidence, with alarms surfaced in the operator's view. The standard choice where the site has a network and a monitoring room.
Design the first thermal imaging fire detection system in your jurisdiction, your portfolio, or your service territory with a device that is listed, prescriptive under NFPA 72:2025, and supported by Flir from layout through commissioning.
