What causes this transparent effect with night video on a 5231-ZE?

Just captured this raccoon in my driveway. This is from a Dahua 5231-ZE using default settings and internal IR. Is there something I can adjust in the Video or Exposure settings to help mitigate this effect? Thanks!

Noise reduction is set too high.

It was set to 15, I'll dial it back to 5 and see how that works. Thanks

Thanks, I'll check it out.

...and a faster shutter and more IR

I'm curious what shutter is used in the default auto settings of that capture. It's pretty dark in that area, I'll try a manual shutter setting of 1/60 tonight. That raccoon is pretty consistent about visiting overnight.

 

[bigredfish]

I think 1/30 but agree I’d try 1/60 for starts and maybe add some IR

So they raccoon came back overnight. Here is the capture using the attached settings. I guess I'm thinking a 5231-ZE should be a little bit better than this.

The only way you're going to improve that is add some more IR. What distance are we looking at here?

That's about 20' from the camera.

Here is a fox I captured last night with a IPC-HDW2231T-ZS-S2 using default settings. Just built-in IR in an very dark area about 20' away from the camera.

The 5231 series is a bit long in the tooth at this point, but agree with @sebastiantombs and as I mentioned, more IR would help.

 

[aristobrat]

The newer 2231 S2 (and the 3241, which looks like it’s pretty much the S2 version of the 5231) both have much improved minimum illumination specs.

More IR will make a world of difference. Here is an example from one of my Dahua IPC-HFW1831E (4K bullet) cams with lots of extra IR lighting. This camera is less sensitive than the 5231 series.

Rarely will leaving a cam in auto at night result in the best the cam can do.
Also, instead of using shutter priority, use manual. That will help a little.
But yeah, more IR light.

I'll try this setting tonight unless you see something to change. Thanks!

You’ll have to walk back and forth (or get the wife or dog to do it) while you play with settings to really see what effect each change has. 1/60 should be close, 5 on DNR islikely to get grainy. You need to add light. Either white or IR

that actually looks pretty decent. you should see my 5241, i can't get it to read a license plate at night to save my life.

From the posts I've seen in the LPR forum, capturing a license plate at night usually requires a stupidly fast shutter speed, like 1/2500 or something.
