Sony SNC-VM630 The camera specifications indicate that the camera has WDR equivalent to 90 dB with View-DR technology. Interesting, there was a study that indicates the Sony performed better with the 90 dB WDR when the camera's enhancement technology was utilized, than the cameras with the 120dB noted below.

Samsung SNV-6084R

The specifications for the Samsung camera say that it has 120 dB of WDR.

Hikvision DS-2CD7254FWD-EIZ

The specifications indicate the camera has 120 dB of WDR.

March Networks MegaPX 5 MP Camera: A WDR of 93 dB is used. Officially this is a true WDR camera but at this value it is considered slightly less than what most manufacturers rate their cameras as when considered as "true" WDR (100 db+). The 93 dB however is probably just a conservative estimate

GeoVision GV-FER5303 Fisheye Camera: At a WDR rating of 72 dB, this is almost definitely not true WDR (and is in fact not rated as having a WDR Pro Sensor like other cameras from GeoVision that have a 100+ db WDR rating).

Uniview IPC2324EBR-DPZ28 Motorized Bullet Camera: The camera specification refers to it having an "Optical WDR" of up to 120 dB, which is most definitely True WDR. On the field tests by IPVM have shown that another Uniview IP camera with similar WDR specs has delivered quite good WDR image quality.

Panasonnic WV-SFN531 133db true WDR

Hikvision DS-2CD6412FWD-XX

Interesting all the marketing material says True WDR 120db, but yet if you look at the above pdf it also mentions DWDR!

Axis P1224-E

Thought I would throw this one in there. Doesn't mention it so probably does not have it!

Axis M3005-V

Axis state on their webpage WDR. Not until you look at the data sheet that it only states "Wide Dynamic range - dynamic contrast". No mention of any db rating so would have to say that this is a fake WDR.

Sony SNCEB632R

This model of Sonys cctv range states "

• Extremely Wide Dynamic Range to 90dB achieved with View-DR technology

As referenced in IPVM this term View-DR makes this a true WDR camera.

Axis P3365 - Could not find dB rating. Listed as Dynamic Contrast which means it's a fake WDR

HikVision DS-2CD2122FWD-IS - 120dB True WDR

GV-MDR3400 - 100dB True WDR

Sony EM631 uses extremely wide dynamic range up to 90DBs. According to our reading I believe this to be True WDR.

Axis P3367- states it uses WDR- Dynamic Contrast but cannot find a DB rating. I found a DB rating of 120 for the Axis P3384

Arecont- AV3226PMTIR- States it offers True WDR up to 100 DB

Other than not being able to find the DR rating for the P3367 the others i believe to have true WDR.

Toshiba WD51A - it says in the spec sheets it has 'true WDR' but does not provide a db rating. So, now I am suspect....

HanWha Wisenet Series PNV-9080R WDR at 120 db - So, true WDR

Panasonic WV-SFV631LT states it has "Enhanced WDR" - couldn't find a actual db rating on the spec sheets.

Bosch Dinion IP 7000 HD - has "High" dynamic range - true WDR - "dual exposure process"

Axis Q36 - has WDR "Forensic Capture" - true WDR

Hikvision DS-2CD2522FWD-IS - claims 120dB WDR - no explanation of type - suspect its electronic

Hi,

Here are my 3 cameras

HikVision DS-2CD2122FWD-I (W)(S) says it has 120dB True WDR

Axis P1364 Fixed Camera has up to 120db

ACTi E78 claims to have an Extreme WDR (145db)

Best,

Samsung SNV6084P (Dome) - WDR (120dB, 30fps@2MP) True WDR

Samsung SNO-6084R (Bullet camera) - Enhanced WDR (100dB) / 30fps @2MP WDR true WDR

Samsung SND-7084 (Dome) - 3M real-time WDR (Max. 120dB) True WDR

Hikvision DS-2CD2132F-IWS Digital(Fake) No dB rating posted

Dahua DH-IPC-HDBW13A0EN Digital(Fake) No dB rating posted

Honeywell HDZ30X True WDR >75dB

Oddly I thought they would post their rating loud and proud. But I had to locate a totally separate document to get their decibel rating at all. Not a lot of any camera manufactures seem to have real WDR. Perhaps the point of this assignment?

My 3 Cameras

Acti E48 70dB WDR Standard WDR

Acti E39 145dB Extreme WDR Future model not available

Axis Q3505VE 120 dBForensic WD

Extremly confusing marketing practices. Great feature but obscure explanitations as to how and why each manufacturer is acomplishing this. As usual self generated specifications without 3rd party oversight so who knows if it works based on their litterature.

Hikvision DS-2CD4A25FWD-IZ: the Wide Dynamic Range is 140 dB. This dynamic range, together with the “FWD” in the model number, indicates it is True WDR.

Dahua IPC-HDBW8331E-Z: the specifications on “Backlight Compensation” include the following:

Backlight Compensation (BLC) which is a single exposure of the camera which optimizes exposure in the foreground and background,

Highlight Compensation (HLC) which is a single exposure of the camera to which image processing is used in order to reduce overexposure from strong light sources like headlights or spotlights

Ultra WDR @ 140dB

Although the WDR is very wide, which would let me think of true WDR, the existence of BLC and HLC makes me conclude it is fake WDR, because true WDR would not need the coexistence of BLC and HLC. However, the denomination Ultra WDR

AXIS P1435-E: the datasheet refers to “Wide Dynamic Range-Forensic Capture: Up to 120dB depending on scene”. Although there is no much information, the forensic capture and the 120dB let me conclude it is True WDR.

Samsung QND-7010R

120 db / True WDR

Dahua DH-IPC-HDBW4421F

120 db / True WDR

ACTi B53

110 db / True WDR

Arecont AV12186DN: This camera model does have "true" WDR capabilities according to the manufacturer but we know this with it having multiple exposures. It has a WDR of up to 100dB allowing users to see clearly in shaded and bright areas of the scene simultaneously.

Samsung SNV-6084R: The WDR rating on this camera is 120 dB, more than enough to assume this is a "true" WDR camera.

FD-202Ne V6: This camera manufacturer claims to have WDR, but with no decibel value, so we can assume it is not a "true" WDR camera without testing.

Bosch Flexidome IP micro 5000
76dB (1080p), 65dB (5MP)
Not a true WDR based on the dB rating.

Avigilon H4A HD Series cameras < 5MP

Arecont AV2556DN

Unsure about WDR because of the "up to" statement

Arecont AV1255PMIR-S - True WDR @ 69dB

Arecont AV2256 Series - True WDR up to 100dB

DaHua PC-HF8232F - True WDR @ 120dB

Advidia A-54 V2

Hikvision DS-2CD4526FWD-IZH

• True WDR 120db

Sony SNC-EM632R is using View-DR technology with a dynamic range equivalent to 90 dB.

AXIS F1025 sensor used with F44 main unit supports Wide Dynamic Range (WDR) – Forensic Capture Up to 120 dB depending on scene.

Bosch DINION IP bullet 5000 HD reports a Wide Dynamic Range of 76dB however which kind of DWR it does not specify. Using IPVM cheat sheet and camera finder we can safely assume it is not a “true” WDR but a DWDR type .

Panasonic WV-SFV631L – WDR = True WDR
- Enhanced Super Dynamic and Adaptive Black Stretch technologies deliver 133 dB dynamic range compared to conventional cameras.

Panasonic WV-SFV531 - WDR = True WDR
- Enhanced Super Dynamic and Adaptive Black Stretch technologies deliver 133 dB dynamic range compared to conventional cameras.

Panasonic WV-SFV481 – WDR = Listed as “Wide Dynamic” and I’m unable to find dB rating anywhere (website, marketing materials, manuals, spec sheets, etc). Also on IPVM WDR Cheat Sheet, the Panasonic “True WDR” column does not include ‘Wide Dynamic’. I have suspicions about whether this camera has True WDR.

Since we recently implemented several WV-SFV481s, I figured I’d grab some screenshots to compare:

WDR OFF – Fisheye View

WDR ON – Fisheye View

WDR OFF – Demorphed

WDR ON - Demorphed

Hikvision, DS-2CD2732F-IS : 120db = TRUE WDR

Samsung, QNO-7010R : 120db = TRUE WDR

VIVOTEK, FD8382-VF2 : 70db = fake WDR

Good Day,

The first camera I looked at was the Avigilon H4SL Dome. The data sheet lists a dB rating of 100 and elsewhere states "Dual Exposure Wide Dynamic Range" which indicates "True WDR".

Next up is the PELCO EVO-05NMD 5MP 360° SURVEILLANCE WDR CONCEALED OUTDOOR NETWORK CAMERA. The data sheet has "Enhanced WDR" and further down lists "Electronic WDR with a 60dB rating. Clearly this is not an example of "True WDR"

Lastly, I looked at Arecont AV2556DN. The spec sheet lists WDR up to 100dB. Further examination of their website finds a page explaining WDR and containing this text:

"WDR cameras achieve a good overall exposure of the image by capturing two exposures one short and one long. The two exposures are then combined to produce a single shot with good overall exposure."

This indicates to me that the "WDR" listed for this Arecont camera is reporting "True WDR"

Regards,

Michael

I looked at an Illustra, a Ganz, and a Sony camera to see if they had true or fake WDR. My results are below.
