“. The images were taken consecutively and 1-second apart. It is not a leaf in the foreground or any type of weed or plant. My camera detects heat and motion, so whatever this was, it gave off heat and also moved.”
A motion detector that also senses heat? Sounds a bit extreme. Out of idle curiosity I checked the website he linked and ii found as mention of motion detecting but no mention of heat sending.
It looks like it has only a motion detector. Some of these cameras do have an infrared flash, but this one only has incandescent.
