Very low light optical cameras, IR illumination, and thermal cameras are options for seeing in the dark.
It was a dark night with just a small sliver of the moon shining through the trees. The mouse nosed its way through the underbrush using its nose to find small nuts and berries. Unknown to the mouse there was something watching from a tree limb high above. The owl was able to see the mouse clearly even though there was hardly any light. Poor mouse. He had no idea he was in trouble.
How does the owl see in the dark? This article describes the various ways that animals, and more importantly, video cameras can see in the dark. We discuss how cameras make use of the limited light available, IP cameras that use IR illumination and thermal cameras that use thermal imaging technologies.
