  • SharpEye 20/20CTIN, Spectrex Inc. - SharpEye TM CCTV Model Flame Detector Manual – TM 788100, Rev. A January 2005 1 1. Scope 1.1 Product Overview The SharpEye CCTV Model Flame Detector (20/20CTIN and 20/20CTIP) is a self- contained, triple-spectrum, optical flame detector that incorporates a video color camera. The detector's IR sensors and spectral band pass filters have been selected to ensure the greatest degree of spectral matching to the radiant energy emissions of fire and the lowest degree of matching to non-fire stimuli. The color video camera enables the user to investigate the monitored area
