Abstract
The present invention is directed to methods and apparatus of detecting engine ignition. The invention generally includes a camera assembly to detect electromagnetic spectra, and a control assembly operatively interconnected with the camera assembly to monitor and evaluate the spectral data collected by the camera assembly. The control assembly is generally programmed with first and second predetermined thresholds associated with respective first and second electromagnetic spectra, and a time threshold at least generally associated with a first time parameter in which at least one of the first and second predetermined thresholds should be reached.
