Lpr cam help hopefully last time

There is just the camera AI sensing the vehicle.

I notice that I only have the ability to zoom and focus on live view page. Is the focus different on day and night or all the same?

If you set up a day profile and a night profile (like one shutter speed for day and another at night and force it to B/W instead of auto/color at night), then you will have to adjust the focus when the camera is in the day profile and when it is in the night profile.

But in the settings you will want to set the focus to manual so that when you adjust it say tonight on the night profile, it will then remember the focus you set it to.

Ok so if I put focus on manual, then go to live view and focus it on day profile, then again tonight in night, it will remember when it switch between day and night?

It is supposed to.

Which camera GUI do you have - the grey/black screen for settings (old GUI) or the newer GUI that is white screen for settings?

The newer GUI shows to hold the day and night focus.

The older ones are problematic for some and they use this utility.

Dahua day/night switch utility - DahuaSunriseSunset

I wanted to use stronger noise reduction at night and weaker during the day, but Dahua seems to have made a mess of the profile management. On most cameras, there doesn't seem to be a way to have the camera switch automatically between Day and Night profiles when the camera changes between...

I think it's the new. It's the blue login screen and white settings. Not the grey

 

[wittaj]

Yeah it appears the new GUI is much better at holding the focus numbers, so you should be good.

Thanks for your help. Had poe cams for 7 years and had no clue about exposure settings or any of this stuff. Running much better picture now. My daughter's bike got stolen out of our front yard and saw the whole thing on night vision and couldn't make out who it was or the plate. Useless. Think I'm good now.

Can't figure out this night thing. I'm at 1/2000. First is me driving by at 40mph. 2nd is the next guy 3rd right behind him and can't read. Is this lighting exposure or focus?

Try increasing your gain and readjusting your focus. Here is what I'm using:



With these results:

You still might end up with the better results staying in B&W 24/7 with a day AND night profile for shutter and gain variances. ....because giving an LPR cam 2 jobs complicates the one thing it does well..
I eventually found 24/7 @ 1/2000 to be solid for my parking lot scenario ,,,but with with a manual gain range for the day and another for night. It was focus hunting when it switch modes every morning and evening, and i was missing plates....

 

[Flintstone61]

Now the 4Mp Bullet version of the 5442-z4 can switch back and forth with my home BI setup for plates but im at 50-60 feet (30 paces-3pontoon boats) on 1 and 70-90 feet (5 pontoon boats-45 paces) on #2,
Hopefully you can dial in it better. A trick i picked up from a Jidetech owner with a 2mp PTZ was to try and put a piece of reflective tape in the scene to get the camera to focus on that either on auto or manual focus....that crisped up my plate shots.

sometimes it all about the right angle....as this car turns more frames become viable as the best reflective angle is captured eventually before he gets out of range...I'd say a 5241 might be better at this location sometimes.

thats a long ass shot for a z4!

Going to try the reflective tape and refocus in b/w 24/7

So basically b/w 1/2000 24/7 no switching profiles?

 

[sdiamond808]

Looks like you just need to get it focused now. Have someone stop a car in the center of the frame and get a good focus.

Messing with this and reading all past posts, you are a similar distance as me. Do you run b/w 24/7 and just focus once? Also if 24/7 b/w do I still create 2 profiles for let's say 1/4000 day and 1/2000 night or just 1 profile and everything thr same day night 24/7 b/w?

 

[Flintstone61]

You can experiment with that, and/or B&W with a day profile and a night profile.....
I can't get access to my 5241 at the Condo as I dont work there anymore....So best as I can recall I had settled on a Gain range, of 0 to about 70-75 and a manual shutter of 1/2000.

here is the reflective tape....its a chunk of 3m trailer tape for the crash bar/dock lock bar on a semi trailer....
