Key words:
Ultraviolet Temperature Measurement,Early Warning
Ultraviolet thermal imaging fire detectors can simultaneously acquire visible-light images, infrared thermal images, and UV ultraviolet light signatures. They enable monitoring for smoke, open flames, overheating, and abnormal temperature rises in the monitored target, as well as early warning of arc faults and electrical sparks. These devices also feature fire-point localization, local audio-visual alarms, alarm notifications, and video verification capabilities.
Product Features:
① Detection method: synchronous multi-spectral acquisition in ultraviolet, far-infrared, near-infrared, color, and black-and-white bands.
② Multi-camera vision: Simultaneously supports temperature detection, flame detection, and smoke detection, all processed by the same DSP, enabling the detection of even the smallest flames.
③ UV light: high-sensitivity, high-precision detection; maximum detection range up to 20 m; wide-angle detection with a 120° field of view.
④ Pre-positioning of over-temperature warning, temperature-rise anomaly warning, early smoke detection warning, and flame detection algorithms, with independent fire-warning functionality.
⑤ Image positioning: The system can output the precise coordinate information of fire hotspots, facilitating the positioning of fire-fighting cannons or robots.
⑥ Thermal imaging sensor type: vanadium oxide; effective pixels: 256 (H) × 192 (V); fixed-focus lens: focal length 3 mm
⑦ The visible-light camera is equipped with a 4-megapixel, 6-mm HD lens, with a detection angle of ≤42° horizontally and ≤37° vertically.
⑧ National standard: fire response time of 1–10 seconds, detection distance ≥150 meters (for a 0.1 m² gasoline fire).
⑨ The detector can output fire alarm information, fault information, probabilistic information, and fire location information.
⑩ Detector supports RS485/RS232 communication and dry-contact relay output, enabling connection to an input module for interlocking with the fire alarm control panel.
⑪ Video Interoperability: Supports the ONVIF protocol, enables seamless integration with traditional CCTV surveillance platforms, and provides an SDK.
⑫ Early warning for detector contamination (≥ 60%), deflection (≥ 60%), and obstruction (≥ 60%)
⑬ Strong anti-interference capability, effectively eliminating reflections from sunlight, as well as interference from electric welding, oxy-fuel welding, TIG welding, and artificial lighting.
⑭ The detector supports a 128 GB micro SD card black box with alarm-triggered pre-recording.
⑮ National Standard GB 15631-2008 “Special Fire Detectors”
⑯ National Standard GB/T 28181-2011 “Technical Requirements for Information Transmission, Exchange, and Control in Networked Security Surveillance Video Monitoring Systems”
⑰ Supports wired, 4G, and Wi-Fi—choose one.
