My $.02 -  Seems to me WDR seems to be a non-factor moving forward in 2019 when choosing camera.  This feature seems to be pretty common in camera >$200.  This seems like standard for typical cameras, specialty cam (fish, pinhole...) excluded.

Specs: There is no dB rating on advert for U.S or Chinese sales. Downloaded manual which lists only two modes of 50HZ and 60HZ with no further clarification. Despite high price tag, no confidence that this is true WDR per the failure to extrapolate on the feature in the manual and the low HZ.

1)

AXIS Q1785-LE Network Camera

This is a camera with true WDR.

“Our WDR technology solves this by applying multiple exposure levels, contrast enhancement, and advanced algorithms that lower noise and increase the image signal”

2)

Bosch AUTODOME IP 5000i

I’m saying this has true WDR capability because it performs close to 100db (and the cheat sheet says all bosch cameras support true WDR).

“High dynamic range: 94 dB (measured according to IEC 62676 Part 5)”

3)

Vivotek FD8166A

This camera offers “fake” WDR because it states a dynamic range of 70db.

This is their new 4MP dome.  The datasheet states 120dB True WDR

Axis M5525-E PTZ

This camera doesn't state its WDR rating is.  It simply states that it has WDR- forensic capture.  Which is combining dual-exposure and local contrast enhancement methods (https://www.axis.com/en-us/learning/web-articles/wide-dynamic-range/forensic-capture).  To me this sounds like a combination of true and digital WDR.

NEXCOM - NCo-301-VHR

• 3MP @30fps, Full 1080P @60fps
• Motorized lens 3-10 mm F1.4
• Advanced P-Iris
• 100dB true WDR
• IK10 vandal resistant, IP66
• Smart IR with 25M

@100dB it would appear that True WDR is accurate. Would be interested to see how they arrived at exactly 100dB though and if it truly is actual True WDR.

Uniview - IPC868ER-VF18-B

http://en.uniview.com/Products/Cameras/Pro/IPC868ER-VF18-B/#~Product%20specification

They list WDR as >52dB & they do mention that it's DWDR. I've actually tested this camera against other cameras and DWDR compared to true WDR is quite noticeable -

Uniview camera - DWDR

OnCam camera - true WDR

Sony - SNC-EM630

https://pro.sony/ue_US/products/minidome-cameras/snc-em630

This is an odd one - it says Dynamic Range, Equivalent to 90 dB with View-DR technology. Sony claims that View-DR is "designed to surpass conventional wide dynamic range (WDR) systems" but the spec mentions its "Equivalent to 90 dB" which would spec it below True WDR. I'd be really interested in seeing the test results on this camera and Sony's claims about it being superior to WDR.
