Frustrate: Blur....

[bbwolfe]

Camera: Dahua Technology AcuPick N85FB6Z4 8MP Outdoor Network ePoE Bullet Camera with Night Vision

• 1/1.8" progressive scan CMOS sensor
• 3840 x 2160 resolution video at 30 fps.
• Four IR LEDs provide up to 394' of night vision.
• 8-32mm motorized varifocal lens

I just cannot seem to tune this camera to stop the moving car images (video) to be blurry.

• I've set the frame rate to max. 30ps (and tried lower).
• iframe rate to match frame rate
• shutter speed to everything from 50 stepping up to 10000.
• I've tried the cameras AI setting, as well as their Adaptive default settings
• tried each zoom setting
• Tech support: I've tried Dahua technical support. Interestingly the technician wasn't aware that you can adjust the shutter speed and kept insisting that only frame rate was required to stop blur. I finally found shutter speed adjustment in the "Exposure / custom" menu.
• I've read as many help articles on this site as I can find.

BUT still, I can't get this camera to stop having a blurred image of cars driving by. Their speed is around 30mph.

Any chance someone can provide adjustment setting for me to try?

FPS has nothing to do with the blurriness of a moving image

Set everything to default values of 50
Set Exposure to 0-3 (range)
Set DNR to 30
Video: use h.264.h CBR, bitrate 16,000

Make sure these are OFF/DISABLED

h.265

Imagine that, tech support useless.

In addition to the above, make sure you have shutter set to manual not shutter priority. Otherwise it will crank up gain.

Not sure what your goal is with that camera or if that is just a test angle, but that angle is too tight for plates and the wrong camera to run fast shutter speeds at night to get clean images of a car unless you have a ton of light.

 

[bigredfish]

yeah, I just assumed he was watching cars . My default starting settings are just to show the OP that Exposure (and possibly DNR) are his problem, not FPS

 

[wittaj]

Oh absolutely, but I was preparing for what may be the next set of questions - that the angle is bad for plates and likely that camera will be problematic at night with faster shutters if trying to minimize blur for catching cars unless there is a ton of light!

And to show it isn't FPS but rather shutter speed, here is my 4MP version of the camera at 8FPS

Thank you all for helping. Yes, this may take me a few more questions of you all.
In answer to a few comments:
-Purpose: I am trying to capture a more closeup, clear image of that area. Both for capturing a person walking in (clear face) as well as a clear image of the vehicle driving by.
- I have two other cameras tuned specifically for license plates, both coming and going on this street. It has proven invaluable so far.

I tried setting the tuning recommended. Attached are the images of my settings and the resulting image.
Summary: Still getting blurred image. Lost color....

Show your EXPOSURE tab

 

[wittaj]

Where is exposure tab - that is the most important

I'm having issues uploading that image. I keep trying.... My issue is that that the Security PC is on a separate sub-net and not accessible to the Internet, so I'm taking pictures on my phone, then uploading.

Weird still not showing.

But taking bigredfish image above, match it or make a custom shutter at 1/2000

FINALLY! Exposure settings....

 

[wittaj]

NR is WAY TOO HIGH and is causing the blur.

Daytime should be lower, like below 35.

Mine run about 25

Also don't be running any backlight like WDR or anything.

 

[bigredfish]

Gain 0-50
Now lower DNR to 30

Thank you. I have set it to this and will report back.

Thank you. I am lowering NR now.

In Daytime Blur is two things
Exposure
DNR

During the day exposure 0-2 or 0-3 should be fine and DNR 25-35


You can run pretty much everything else at 50 with just small tweaks. The only other control to watch in daytime is Sharpness. Most Dahua cams are over-sharp from the factory. Try 40

It is getting closer. Here is the current image as well as the new exposure settings.
Not sure what to modify now though.

I changed exposure down to 0-2 and captured this image. Is this about the best I can hope for?

 

[bigredfish]

Ok so you have overcast skies, maybe try 0-4 or even 05 but no more

You can increase Gain a bit and/or Iris but small increments

Make sure NO Backlight option is enabled, No AI SSA, and set your image settings to 50 except Sharpness 40

Do each one at a time and see results before trying something else


Daytime should be easy. Verify thats the Main stream image and not substream
