DS-2DE4A425IWG-E is a new one but specs are identical. They are listing it with smart tracking while old one doesn't list it. Is there any chance it might have improved sensor?
I just ordered the DS-2DE4A425IWG-E and they now also list a third similar model, the DS-2DE4A425IWG1-E . Some of the lens specs are different with a slightly different FOV at the lower and higher end of the zoom for the WG1-E so a different lens is used?But they also appear to have possibly removed the Smart Tracking and some other related features? The sensor size and light sensitivity don't appear to have changed, nor the maximum aperture.
