Appreciate the input. I don't have a great perspective on the road .. as in no overhead perspective. Reading the best practices for detection indicates off center more than 30 degrees is not optimal. I only have a roadside perspective. I will experiment with fps and see if image quality is better. A...

Reading documentation from OpenALPR and Phd papers seems to imply I should reduce my resolution and increase the FPS.

VBR with cap is recommended.

Trying reduced resolution 2304x1296 @ 30fps.

I'm looking for advice on the image quality front. I have a system that monitors a busy rural road corner and would like to do license plate detection, manual or automatic. In the manual case, the still image quality from a Amcrest 4k camera is barely enough. Remove storage size as a limitation ... ...

Missed the step to grant the www-data user access

sudo usermod -a -G plugdev www-data

Works! Huge time improvement over CPU based detection.

Thanks for the confirmation ...

I have a functional zm system 1.35.10 on Ubuntu 20.04.1. LTS Opencv 4.5 from source. Using Yolo4 and working very well. Wanted to try the Coral edgetpu so added a usb 3.1 card and the Google Coral edgetpu. I can run the classify_image test without issue but zm fails trying to open the device. From m...

I'm going to jump to Ubuntu 20.04 and redo my zoneminder install. Something is jacked in my filters.

I jumped to 1.35.9 but continue to see no function from the purge filter. I enabled debug and ran the exposed sql. The events diskspace column is null.

Is it the diskspace filter that is supposed to update this column?

Any help appreciated

One more thing .. can you explain the relationship between the disk space metric and the UpdateDiskSpace filter?

Thanks

Will apply 1.35.8 and test.

Thanks

I had a similar problem and updated to the most current 1.35.6 without resolution. I updated to 1.35.7 and still have the same issue. What am I missing here? There are two filters in the standard build ... PurgeWhenFull and UpdateDiskSpace. Why is there a filter to update disk space? zm-filter-sql.P...

Previous to the new events display you could access all events. The top of the page showed a page indicator and you could easily jump around. In the new view you get 25 events in 3 pages and that's it. Say I want to look at three days ago, you could cycle thru the pages to find three days ago. Has t...

Also, the page control does not work beyond the 3 pages it shows.

FYI

If you choose 25 lines per page you lose the lower right pages control.

I would like to see a >> to jump to the end

New events look is nice.

One question, how do you jump to the most recent events?

In the past you could do this from the pages listed at the top. I assume maybe you would use the timeline but I keep 3 months of history and the timeline is very slow.

Am I missing something?
