    IPC-HDW2439TP-AS-LED-S2 WDR? How?

    Dahua Cameras True WDR (120db) vs DWDR

    Those who are familiar with Dahua's WDR settings will know that the higher end cameras equipped with True WDR (120db and up) are only True WDR when set from 45% and upwards. With WDR on and set to anything below 45% it uses only DWDR - that being software based by only adjusting the gamma and...

    Limitation on WDR setting

    Hi, clicking through the interface of my HDBW2431R-ZS-S2 and trying to optimize the image, I noticed something strange: I can't chose WDR from Conditions - Backlight - Mode, only Off, BLC and HLC being available. After more fiddling and resetting I got it working - but only when Conditions -...

    N222AL12 - trying to choose between back light options at front door (pics included)

    Got it on an 8ft 2x4 (at about 5ft) for testing at the front door. Having trouble dialing this in to get the near field light enough, but not overexpose the street. except for the Backlight options, everything else is at default. This seems like the scenario that WDR is made for. Thoughts as...

    HLC (Highlight compensation)

    I have noticed with HLC on, super bright areas or light sources in the scene get blacked out (for example car headlights that are blacked out), however I have seen footage where HLC does not do this, it simply dims the light source in the scene. Is this possible to adjust to achieve this?
