Gas / Fire Threat Detection System

With multispectal imaging cameras and computer vision analytics

An additional layer of securityConcept

The customer required an additional layer of security over existing fire /gas detection systems in warships and submarines using a visual method of identification. Multispectrum IR flame detectors with a combination of IR sensor filters were used with specialised computer vision analysis software to visualisethe invisible gas fires / leakage and reduce false alarms.

Multispectral identification of invisible gas fires Stream4S Solution

Multispectral Imaging cameras can spot high-temperature objects, gas cloud or gas leakage. It is possible to detect chemical compounds using a camera with NETD lower than 0.2 K. The use of multiple filters allows the camera to simultaneously identify, quantify, and display the type and amount of gas within a family by separating the radiation at the reference and active wavelengths from the broad thermal radiation emitted by the infrared source or background.

Computer vision video processingSystem Specification

A live-feed of images from Multispectral camera is fed into the Video processing unit which then segregates the results from the camera providing the viewer a clear identification of the source of threat. The detected gas / fire threat is presented in the Remote Viewing terminal for real-time inspection where an alarm event is registered.
