It links to DC Rainmaker's page. I was distracted and didn't add any info. Sorry.

The problem he managed to capture in the photo is what happens under low lighting conditions. The plate on the car right in front of him is illegible, due to the headlight in the combo unit, but off to the side, you can see the number on one of the parked cars quite easily. I think his conclusion is that the dynamic range of the detector chip is quite limited.
