Where just talking about the overexposure problem, which also shown in the few official videos on dahua channel. Its somehow hard for me to fight against it.

For sure, the 4MP will be a benefit at day against the 2MP.
But in my opinion has nothing to do with the overexposure of certain parts even if there is no sun.



yeah, not sure if its related to the content/situation of the picture.
I think i will reset the cam at first, maybe it will help.

The night screens you where showing shows the same for me, contrastless face and person, which happens fast.
If you watch the video from jmcu you will see much better face.
But you may also notice the overexposure on his tshirt.

i still searching for some good settings having a good contrast on the face, not wash out most details.

I haven't done much to adjust settings at this point other than guessing, and mostly on the exposure/gain side of things. With the snow right now I both don't want to be outside and not sure I would get an accurate representation. Hopefully I will be able to get back to it soon.

Interesting, looks like a faux-varifocal containing 3 lens with 3 different fixed focal lengths; definitely useful for very specific applications I presume :)

With 8 IRs, I would assume IR Blasting would be hard to control but I have never had that many IRs. Maybe turn off the close up one, have a light On for that area if close to the house?

Having not experienced snow much down South, is it an IR killer (reflective)?

It can be both LOL.

In some instances it allows for much more reflection and brighter images and captures.

In some instances it has kept some of my cams in color.

And in some instances it messes with exposure if the snow is too close and you get IR bounce back to the camera.

When it's coming down? Yea, it can be bad. Not as bad as static on the TV, but similar. My rear camera was being alerted non-stop.

Generally, it helps at night. I just wanted a worst case capture, and also with the path not being cleared no one has been able to walk back there.

This is the most recent night capture I have from before the snow hit.

Another question:

Can you try
auto mode, HLC 50, infrared auto mode on distant channel ?

Or shutter 20, gain 30, infrared auto ?

Sounds maybe bit stupid.. on my testing it looks like the distant channel start noising with too low gain/shutter fast, which ends in worse picture than with higher gain/shutter than someone would dial in on 5442

I can, but I doubt I will get anyone walking by at night.
