Hakarb,
We are installing the DW VF-4, VF-8, & VF-16. I have tried other models and have the same issues. I originally noticed it when recording license plates with a true license plate camera, but anything moving at all has the same problems. If you were to record a car moving at 10 miles per hour when you play back the image is very distorted. You get ghosting and the recording is not very good. Using the clean button fixes the problem and the recording looks fine, but when that video is taken off of the machine it does not come cleaned and there is no way to clean it through the player. If you record at 2cif there is no ghosting, but obviously you are losing half of your resolution.
I tried the new 960h DVR with a LPR camera thinking it might perform better, but no matter what resolution I record at there is ghosting and double images. I could not capture license plates with that DVR no matter what settings I tried. I have contacted DW many times through tech support, dealer reps, and my distributor with no avail.
We did recently use the Spectrum software and we love it.
Let me know if you can help.
