First I want to thank all the contributors and the creator of ZoneMinder. It's a killer tool.
Second. I've got a bit of a problem. In all of my cameras there is some blurriness in motion of an image. To demonstrate, take a look at this:

The idea of the above image was to be able to see the license plate, however that's not too easy and clear.

Thanks,
