just to be clear and a bit scientific.....IR cameras
do not pick up body heat like someone else pointed out - bug, person, whatever. It's merely and intense reflection of IR light being so close or on the lens of the camera.
but yes its a bug...if you watch the video, you'll notice little quick flashes of light around the car (or I should say between the car and the camera lens) This is the same flying bug at a greater distance. The reason its a flashing spot is that these CCT IR cameras are not shooting at 30 FPS. It's much lower to conserve recording and disk space. So you get frames of an illuminated bug but not a smooth video stream.
