EmpireTech aka Dahua LPR Settings

You don’t.

Set focus, leave live page, go back to focus menu and hit save a couple times.

On live page it will always default to 20. Just make sure and change to 1 before making adjustments

Got it - thanks. Right now I have a car out there and am trying to adjust Day setting to be as sharp as possible. I dropped the sharpness which really made things a bit clear, is that normal that a lower sharpness will lead it to be clearer. Am attaching picture of current Day setting. Also, I set the focus to 1 as you suggested.

How do I save the focus speed? If I set it and exit out of the Live Camera view it resets each time I go back to 20.

You can't, it always reverts to 20.

That is only used for how fast YOU manually adjust things.

Yeah it’s a bit different with plates. Too much sharpness usually makes for problems on most scenes anyway.

You need more zoom or you’ll be wearing thick glasses like me before long

alright hard lesson learned did something on Day where now can't even read the license plate - ugh - completely get the frustration.

need to start all over again to figure out what happened - the illuminator on the Day - should that still be zoom Priority?

 

[bigredfish]

Illuminator is for the IR, no good in Daytime. Useless. Off

Nighttime use Manual and 100

Thanks so I'm not sure what ended up happening to my Day view frankly, i went from experimenting with the sharpness to readjusting zoom/focus. I guess I should have written down my existing numbers on the zoom/focus before messing with it - now it's very grainy and pixelated.

I've reverted back to the same settings you had including setting it to H264, the only difference being my FPS can't be switched to 30, it maxes at 25. Also my substream resolution option wasn't the same so picked the closest.

Now, testing night vision - i think it improved from last night possibly - attaching two videos - both cars did come in slowly - so will have to see when someone is at a faster speed.

I had to set the camera shutter to 1/2000 to avoid the flickering/waving light from the street lamp.

2nd ones close.

H.264H - details matter here

You need to zoom in more

Thanks - yeah it was H.264H -- thanks for catching that.

Another car, this is the latest picture. Not zoomed in, not sure if i can improve this further or just be content this point with night and focus on the day tomorrow.

Other than not enough zoom it’s looking pretty close.

Tweek each of the 4 main controls I mentioned one at a time, test and see results. You’ll get it. Small changes.
Make screen grabs NOW of your current baseline settings.

You’re at the stage where bourbon helps and you’ll tweek it a dozen times in the next 3-4 weeks

Do realize:
1. You will probably have to do more fiddling with the settings after you get the proper mounting and more zoom.
2. You will NEVER be totally happy with every capture.
3. As cams age/get dirty, you will have to adjust again.
4. LPR cams keep you off the streets and out of the bars.
