It's a bug. Sheesh. Those cameras have infrared LEDs to illuminate the scene. Those LEDs are pulsed on and off very rapidly. (Waive your LED alarm clock around, and you'll see the strobe effect.)
A bug flew across the frame as the still picture was exposed, and so you got the multiple strobe effect of the bug.

Is that you, Philip J. Klass?

Gosh, everybody thought you died! LOL

I did.

THE LAST WILL AND TESTAMENT OF PHILIP J. KLASS To ufologists who publicly criticize me, ... or who even think unkind thoughts about me in private, I do hereby leave and bequeath:

THE UFO CURSE:

No matter how long you live, you will never know any more about UFOs than you know today. You will never know any more about what UFOs really are, or where they come from. You will never know any more about what the U.S. Government really knows about UFOs than you know today. As you lie on your own death-bed you will be as mystified about UFOs as you are today. And you will remember this curse.
