The "TV antenna"thing came racing across the screen and disappeared in a split second. Any ideas? Thanks. Frank
Bug You are likely seeing four frames - hence the four sets of wings (and notice a few more dimly farther back).
I agree with @K6CCC - that’sa bug reflected in the infrared lights used for night vision. They trip the motion detection and give you lots of false event videos.
You haven’t lived until you’ve had a spider descend directly in front of your cam under the IR lights!
