Hi, there is a video of a UFO that was captured on video by the Chilean Air Force. The witnesses claimed that it could not be seen with the naked eye. But they were able to see and film it with a thermal imaging (infrared) video camera. Will a full spectrum video camera, capture the same type of images as the Chilean camera did? I want to purchase a video camcorder that can detect heat signatures in the sky too? Can anyone tell me the difference between night vision and infrared video camcorders, or recommend one that will perform this function? Thanks.
