5442TM-AS Day Image Quality Issues

Barrel distortion
 
Look at the definition of the cracks in the soil in front of the bush, the old camera had much more detail and definition.

Sorry if I missed it but what Mp is the old cam and the PTZ?

One thing correctly noted by @shalem2014 is that the 5442’s do seem to have an over sharpening effect out of the box. I’ve turned sharpness down (40-45 or so) on a few of mine and it seems to improve a bit.

The other thing I’ve noticed with some turrets, is a barrel distortion along the top of the image when they are pointed at a more severe angle down like your front yard. I’m not a photog so pure speculation, but on my neighbors turrets we noticed improvement by lowering the mounting location to get a more straight on view. Now this could just be we are seeing more sky and less physical objects so that the barrel distortion isn’t as easily perceived?

I am an astute observer; all of my observations on this thread have been correct, not just one of them. We are seeing minimal edge blurring due to barrel distortion. The entire lens/sensor are slightly tilted in relation to each other. This defocuses one entire side of the photo, and exaggerates the expected minor barrel focusing effect, making it very noticeable on the most affected corner due to the axis of distortion.

Look again. Download the attached image and carefully view it 1:1 or even zoomed in. This effect is most noticeable in IR (night) mode due to the mono-wavelength of the IR light and chromatic aberration of the lens. During the daytime, blue would be slightly defocused on the right and red moreso on the left, thus reducing the effect. Look for detail and the fineness of detail, not the over-sharpening shadows. This lack of detail would make the user loath to drop the sharpness because the image starts to look fuzzy, even though it's still oversharpened. Bumping sharpness up to overcome the lack of detail on the left results in the horrible picture in the first post.

Well pardon me. I didnt mean to imply that all of your observations weren’t perfectly correct, I was simply agreeing with one in that comment.

@jd415 You are unhappy with your purchase and It is obvious that it is OOF especially now you have posted night time shots. It wouldn't be any better no matter what settings you used or if you had your monitor calibrated it's a faulty camera which is not fit for purpose, return it for a replacement or refund simples.

These new camera's cost a lot of money now and you shouldn't be expected to strip it down to fix something that shouldn't be broken in the first place. It is not your fault but a Dahua Quality control issue.

Agree. Send it back.

As to barrel distortion, its not uncommon but its more pronounced in the first image. Wider FOV may have something to do with it, just an observation.

I purchased a Loryta IPC-T5442TM-AS from @EMPIRETECANDY after reading all the great reviews from many people in this forum. The night shots are amazing however the day shots compared to my old camera look horrible.

I tried changing all the settings, reset camera to default, confirmed firmware is up to date and also reached out to Andy. Anyone have any ideas?

We replaced a new camea for @jd415 , for all products which bought from us can get warranty or replacement if has hardware issues, we are working with dahua now for faster and better warranty support now.

New camera has been installed and it's no longer blurry on the left side. Thank you everyone for all your help! :)

I just purchased this same camera from @EMPIRETECANDY Amazon store and am having the same daytime image quality issues as you reported. Did you ever settle on specific image settings? I'm not having focus issues, just image quality issues - looks way over saturated / over-exposed out of the box with the default settings. I've purchased a half dozen cams from Andy and have never had problems before.

The ONLY 1 thing you can do if the same problem as above is return to sender for an exchange or refund , no matter what settings or updates you do will not fix this issue of OOF, it is a Quality Control hardware issue.

post a sample clip and your image and exposure settings. And tell us your bitrate
 
I have two of these in use; no image or focus complaints. pretty much everything is default/auto

Agree with @ljw2k though you may get by with Auto during the day, the sensor and camera are that good. But nighttime is going to usually require some changes, especially exposure, to reduce motion blur.*

*Unless you have a bunch of white light

Not set up right then if everything is set to Default/Auto.

In terms of exposure/WDR/AWB I have many cams, some are set for LPR, at least one os set up for True color/Night color. Feel free to show me what must be changed.
 
Motion video is what counts, still images are easy

Understood. I have overlap of five cams on this spot. They don't all have the same job. One is a Night Color with no IR, the others are all IR, various angles, shutter speeds and Focal lengths. This particular cam is not trying to ID cars or capture plates. It is for pedestrian troublemakers. I still need to do testing with it to see if there are blur issues with people, but I'm away right now.

Can post some pics and setting for further checking? Or just send me email for further talking or warranty.
