From the description for the video: This webcam takes 1 picture every 2 minutes. The daytime one (at the beginning) was awesome. I want to know what the streaks are that show up at night. If it is due to a slow exposure/shutter speed on the camera then I would like to know why not ALL of the objects appear as streaks. Some appear as orbs/dots of light that move across the screen in succession to the time.
