Hello SAC
Do you know what small animal is so fast it causes a long blurry white line (like a snake) in a Moultrie trail video camera at night using InfraRed video at 24 frames per second? I have been capturing videos of the animals that travel in my back yard for about 6 months and it fascinating to see them in both daytime and at night. They are the usual small animals, squirrels, chipmunks, skunks, groundhogs, foxes, turkeys, raccoons and deer. But this one stumps me. It is so fast all I can see is a blur. I looks like it hops. At one point in the video it looks like it stops to jump up on a snow mound and it looks like the size of a mouse, but it is out of the range of visual acuity so I can't tell what it is. Any suggestions?
