What about the DS-2CD4132FWD-IZ?
DWDR sounds like Digital WDR, not the same.
What criteria were you using when searching for cameras? I have a list of 60 cameras that match your specifications. What cameras were you looking at that you found to be out of production?
Also, to answer your second question, DWDR is not true WDR. DWRD is "Digital" wdr, which functions similarly to BLC (backlight compensation), making dark areas brighter but also possibly overexposing bright areas. Generally, we have seen very little practical difference with DWDR.
"True" WDR mainly consists of a camera able to take 2 seperate exposures (A high and low exposed image) and combine them into one image, as seen in the example below:
Chris is correct, DWDR stands for Digital WDR and, in our testing, performs very poorly against true WDR cameras.
