Hikvision DS-2CD2142FWD - V5.3.3 - Ghosting

[Pedulla 0]

Just put in a couple of the new 4mp cams. Both are exhibiting the same symptoms.

As someone move across the scene, their image ghosts behind them, trailing the motion, not a smear from to long an exposure.

The ghosted images slowly fade in about 4-6 frames. (running 4fps)

The ghosting occurs on both streams.

Almost like a compression algorithm glitch.

When the scene is still, image crystal clear.

 

I messed with various exposure and smoothing settings, no change.

 

Anyone else have this problem with the new 4mp cams?

 

For the record I have have several of the 3mp in play and working great.

 

Any ideas?

Is this viewed from the web browser or from an NVR?

That's a really good question.

The artifacts that look like compression issues could be an error in the decompression...

 

My observations were views from the NVR (zoneminder). The camera network is physically isolated so I'll need some volunteers to wander around the scene while I watch the web interface directly.

 

It's a non-profit gig, so helpers should be easy to come by.

 

For the time being, I'll put this one on hold and report back on my findings.

Issue discovered.

 

It's the Digital Noise Reduction (DNR) setting in the image enhancement section of the camera's config.

With DNR on and a setting over 50 the ghosting becomes intolerable.

 

The 3M cameras do not have this problem, so you'll just have to deal with the noisier picture of the 4M cams in dusk to dark conditions. This also means, in my case, fiddling with the motion detection array of settings to not trigger on the noise. ZM's pretty good for that.

 

Hope this helps someone else from pulling their hair out.

That's all folks, I'm out.

Thanks, I had the same issue, changing the DNR back to 50 fixed it.
