Conventional surveillance cameras are already capable of capturing video in daytime and well-lit areas. However, when faced with a poorly lit area or at night, these cameras? video capture abilities begin to diminish as sensors must compensate for the lack of light by increasing sensitivity, thus producing a noisy image, if one is produced at all. Since clear day and night monitoring is an important benchmark in assessing a surveillance system?s effectiveness, thermal imaging devices present a clear advantage in their ability to convert heat energy into an image visible to the human eye.
