which setting causes 5241E-Z12E blur with even slow motion?

^As do many of us.

Maybe he is used to the cheap cams that won't run at that even if you tell it to lol.

But no freaking way we get night plates if not a fast shutter lol
 
Im just guessing cause I think he knows better, I think he was referring to the OP
 
Let's see if I can get this math roughly correct. I believe 1 mile per hour = 1.46667 feet per second = 17.6 inches per second

Using that info, and assume a vehicle moving even 30 miles per hour, that's 528 inches in one second. A shutter speed of 1/2000th would capture up to roughly a quarter of an inch (0.264) of movement if that movement was perfectly perpendicular to the view of the camera, which of course it won't be or we couldn't see the license plate.

So now I think we take the sine of the angle of your camera to the license plate, and multiply that by 0.26 inches (someone please correct me if I'm using the wrong trig function). Sine of 20 degrees is 0.34, and sine of 30 degrees is 0.5, so it's not unreasonable that a plate could move 0.08 to 0.13 inches in 1/2000th of a second. A speed of 45mph would obviously increase the movement by 50% compared to 30mph.

My comment above was that even at 1/2000th of a second, that might equate to 1 pixel. So take 0.13 inches for 30mph (or ~0.2 inches for 45mph) and map that to pixels using the camera resolution & size of the plate in the image. That's obviously different in every situation.

Assuming you're running Cat 6. It's effective range is 328 ft. I'm assuming this was implied from this post.

Camara networking issues, packets are not the only thing you can drop.

Video from your post #15 reminded me of a problem I had with a HFW5241E-Z12E.
Hikvision NVR manual said check this box and you can run ethernet cable to 1000 feet
Cool, checked box and roughly 750 feet of UV solid copper cat 6 cable later had a little bullet camara
grabbing overview pics, followed about a week later by freshly shipped Z12E from Andy.
Dialed Z12E in and was rewarded with nice license plate pics at about 170 feet from camara
Aghhh... daytime only, nighttime infrared no matter what i did stationary plates could read, however any moment and blurring ensued.
Shutter speed, DNR, WDR if it was adjustable i tried it, I failed.
Love this site, have learned so much from other members, but i finally gave up on this problem.
Added more cameras, at about a dozen cameras the 16 port Hikvision started dropping frames.
Wanting more bandwidth/processing power got a NVR rated to 64 channels.
they don't put 64 ports on the back of these things, so now I needed a POE switch.
I was burning thru boxes of cable making runs 100's of feet long.
Figured why not spread out a few unmanaged switches
now all runs are under 300 feet.
Short time later viewing video I noticed the Z12E night recordings were no longer blurred.
Z12E is now about 60 feet from a switch.
I believe the 750 foot network cable run dropped POE little enough that colour
still worked, yet power drop to much for infrared to work correctly.

have you tried 60fps or 30fps?

also try setting I-frame to 2x whatever the frame rate you are using
 
I know this is an old post but I am having the same issue with the blurring in the middle of the FOV but not the edges (left and right). Was there ever a fix for this?

My camera is a brand new IPC-B52IR-Z12E-S2 I purchased during the summer sale. I've spent the last 2 months trying everything to resolve this. I've tried everything in this post (even the 3 reset procedure twice). Only thing I have not done was try to reinstall/upgrade the firmware.

I had no problems at all with the first camera of this model that I installed for LPR and it's zoomed in 99.9% (1200 of 1202) and capturing plates at least 140 feet at night with no external light. I thought this one would be a walk in the park since only about 100 feet away.

Here is my firmware version for all 3 of my cameras (just purchased a 3rd refurb during the winter sale).

Device ModelIPC-B52IR-Z12EB-S2
ONVIF Version22.12(V3.1.0.1403710)
System VersionV3.100.0000000.6.R, Build Date: 2023-08-02
Web VersionV5.01.0.1532205
Algorithm VersionV3.5.26.0
Security Baseline VersionV2.3

Since they are all the same software versions I didn't think it was the version but maybe something is corrupt. That was why I was saving the firmware upgrade as a last resort.

Also, for the reset procedure I just want to make sure I did the correct process. With the power on, I held the reset button down for about 10-15 seconds (till I heard the click) and then let go. I waited at least 2 minutes and then repeated again two more times (without ever logging in). I'm assuming that is the correct procedure?

set shutter speed to 1/200 or faster
disable WDR or similar

Yep already did all that at the beginning. Like I said, I tried everything mentioned in this thread.

Here are current settings although I have tried MANY MANY different configurations:

AI SSA Off
Image all settings are 50 except Contrast set to 60
Shutter 1/2000
Gain 0-60
Iris 45
Exposure Comp 50
3D NR 30
2D NR 30
Backlight Off
WB Auto
Day/night Color for Day and BW for night
Focus Manual (adjusted for both day and night accordingly and more on that below)
Illuminator (off during day and 100% for far and near at night)
Defog off

Encoding
Compression H.264
Strategy General
Resolution 1080P
FPS 15
Bit Rate Type CBR
Bit Rate 8192
I Frame 15
SVC 1 (Off)
Smooth Stream 50
Watermark on

Zoom 1125
Focus Day 1062 / Night 1084

Focus was dialed in using the "1" speed with a parked car with the LP in the center of the FOV. Neighbors looked at me crazy since the FOV is the property line (They were wondering why was I parking my car there so far away from my empty driveway :screwy: LOL)

At first I even tried different cables, POE switch, POE injector, etc. just in case.

There are a couple of times where I thought I had it but didn't. Even in perfect environment LPR is never perfect. My other LP cam is working almost perfectly (don't want to jinx that camera). Even the other camera can still miss a plate with Sun glare/reflection during the day and dirty plates/covers (and even manipulated plates) at night.

Big negative with setup so far is when there is rain, snow, or fog it's almost useless at night. But that is not the cameras fault. That is the fault of the environment. Unfortunately I don't have anywhere closer I can put them (I'm trying not to make them obvious).

Just to reiterate, the problem I have is the LP is in focus on the left hand side and right hand side of the FOV but gets blurry in the middle as the LP/car travels from side to side. If the LP/car stops in the middle it is in focus. I hope I didn't put this in the wrong thread as I have been ready dozens trying to find an answer LOL. I hate to have to reach out to Andy and possibly have to exchange this camera.

Not sure of this is the issue you are describing, but you could try a try a fixed ( manual) focus. Use only 1 capture area where the camera is focused to. Like another member here who shared a good idea here 2 years back...use a small piece of reflective 3m tape somewhere in the area of interest. And get the camera to focus or be able to sharpen up the reflector light crisp as possible on the reflective tape. Or at least focused on the tape. I did this with a Z12 with good results, and now with a Z4e with good results.

Not sure of this is the issue you are describing, but ...

Different issue.

I am already using manual focus for both day and night. I set the focus by parking my car where I wanted to read the plate and set the focus with both day (color) and night (IR) since they are different. The reflectors are a good idea as another option if someone can't park their car. Thank you for that.

My problem is as the LP (License Plate) enters the FOV (lets say from the left) it is in focus. As the LP moves to the right it gets out of focus when it is in the center of the FOV. Then as it moves further to the right it is in focus again right before it goes out of FOV. The road is straight and not curved so if anything the LP should be in focus in the middle of the FOV if anything or fading one way or the other.

It is almost as if the camera is trying to "adjust" as the LP moves across the FOV but

I know a video would help and I thought this was the thread where someone posted a video of the same problem but I don't see it so must have been another thread.

I'm going to try some more tweaking and if I can not get it resolved I'll create a new thread with a video.
 
@AlwaysSomething you didn't show sharpness or saturation in your settings list above. If you look back at one of my previous messages in this thread, you'll see that I found those settings have a HUGE impact on the clarity. I found that I had dramatically better results with those values down in the 0-10 range.

Having said that, my images appeared to show a different effect that your sample images show, so I don't have high confidence that it will solve your problem, but I know it makes a big difference for me so make sure those values are low.
 
Image all settings are 50 except Contrast set to 60
Shutter 1/2000

So Sharpness and Saturation are 50
Shutter is fixed.

Those aren't my images.

I tried the lower sharpness and saturation settings but it didn't help. It sounded like you were making progress but those weren't the end all fix which is why I asked.

I wish the camera log tracked changes and then I could search what I tried as well as copy it here. I did add an overlay that I put the settings in but sometimes forget to update. That allows me to at least compare footage between changes. I'm trying to make minor tweaks so takes a long time to test everything.

One thing I learned (which others have mentioned as well) is that dusk and dawn are tough. I keep forgetting NOT to change things based on results at those times.

Unfortunately there are cars parked and blocking the street where the camera is pointed so won't be trying anything tonight.

Sorry if I sound rude... been going through a lot and this day just keeps getting worse...

Someone also parked half way into my driveway :mad:.... no respect.

Thanks to cameras ;) I was able to see they went to my neighbor that I get a long with so won't complain.

I deal with this crap all the time now which is why I started buying cameras. 17 year old across the street is a problem child. He threw a couple of internet parties (with his mother home every time she did nothing), straight pipes on his Mustang which he comes and goes all hours of the night (from dusk to dawn)...:banghead::mad::angry:

I need to move to the country... buy some thermal cameras from Andy and a thermal scope for my... ;)
 
I experienced what you're talking about with the target seemingly blurring in the middle of the scene. It was very noticeable over approx 20ft of capture area
For me it was fine tuning from 939 zoom/1590 focus to 939 zoom/1593 focus YES, that little bit of focus made a difference.

There's still a hint of it if you go full screen and go frame by frame, but its acceptable now

5241 Z12- S2 , 100-120ft, added IR + Camera IR, 1/1000, 8192 bitrate

Well here's a spoiler...snowed all day and many of the front plates are covered in snow or road grime. :/
