Dirty Dome Camera Test

Author: John Scanlan, Published on Nov 28, 2016

Dome cameras are the most widely used type professionally but many note that dirt, dust, rain, and scratches can cause image quality problems, especially with integrated IR.

We tested an integrated IR dome with these very issues to see how it impacted images day and night, testing the dome with light and heavy fingerprints, dust/dirt, and finally slight scratches, shown as best as possible below. Note that to the eye, some of these issues were not noticeable unless carefully inspecting, and could easily go overlooked in the field.
