Best settings to reduce grain/noise in sky?

[Peter vB]

Hey guys, sort of new here (posted before in 2017 when I had my first Dahua cam).

I recently bought the full-color HDBW3449EP-AS-NI and I use it as a weathercam.
Anyone else using his/her full color cam as a weathercam and what settings do you use to reduce the grain/noise in the sky at night?
The image is a 1000 times better than my old cam, but I'm wondering if I could do something with the settings to make it even better?
And does anyone know if this cam can capture images at 1/3 second?
It says so on the datasheet, but I believe the manual says it can only capture up to 1/40 second!?



Below is the image that I upload to my website every 5 minutes.
The weather data is added with help of my Meteobridge uploadserver.

I don't do weather cams so someone else I'm sure will have a better answer. Since you're just grabbing a static image every 5 minutes and aren't concerned with capturing motion in this case, you could set the exposure to a low/longer value, set quality/max bit rate to highest, turn up gain a little if needed, turn up noise reduction some, turn sharpness down a little.

Oh wow, thank you for your reply Mike.
I tampered a bit with the settings, like you wrote and the first result is wow:
And I found the answer on my question: you can set it to 1/3 second

Much better!

Once you get it as clear as you can, might try playing with brightness/contrast/gamma and color settings to try to make it "pop" a little more. That looks pretty good to me as is though as far as that goes.
