If you have followed all the best practices above and are still seeing blurry or images with artifacts, you are likely running into the following issues below. This article goes over the different possible causes and how to mitigate them.
Many of these issues are most seen when using IR illumination in night mode, though some issues can affect footage during the day as well.
Proper camera deployment can help mitigate most of the IR reflection causes. In the case of a dirty dome, a can of compressed air and a microfiber cloth can easily remove dust and other debris.
The most common cause of IR reflection is the lens gasket not being sealed against the dome optic and the IR is reflecting off the interior. This is typically caused by the rubber lens gasket being removed during the camera install. To fix this, make sure the gasket is well seated when putting the dome cover back on. It may be required to take off the gasket and only lightly put it back on the lens. Allow the gasket to compress against the dome when it is closed up.
The following image shows an MV21 with the gasket seated correctly.
