I've written code to reset the zoom and focus every hour. Note my zoom isn't drifting, only the focus. The api to do it is documented in this doc latest Version of DAHUA HTTP API FOR IPC Documentation ?? http://{ip}/cgi-bin/devVideoInput.cgi?action=adjustFocus&focus={focus}&zoom={zoom} This...

I don't think it's the case of day/night difference. Both the day and night are out of focus in my case. The camera isn't set to reboot but even so, it should keep its focus though right? For now I'm just going to set the focus via dahua API / cgi every day, or even every hour. Does this not...

Wait.... the focus settings are different for each profile (day / night)? Didn't know that! I think I wrote down the focus settings, but alas I forgot where I kept it!

My IPC-HFW5241E-Z12E focus mode is set to Manual. However, every now and then (about 1-2 months maybe?) I would discover that it had gone out of focus and needed refocusing. I never could remember the exact value for the focus so I have to do a manual focus by parking a car where it's aimed and...

Are they "images" (as in jpg)? And do I need to store actual clips, duplicating the video data, since it should also be stored in the big bvr file? I have unticked the 7 days settings for now.

Limit clip age for the "Alerts" folder was ticked and set to 7 days. But I thought that was just for the actual video clip files (mp4). I thought the red dots being markers in the database, would then play the video from the main bvr which is stored until the disk limit is reached. The oldest...

I thought those red dots are just markers in the database?

Why do I only have 6 red dots on the Alert calendar? (My system has been running for months). How can I browse past alerts?

I recently found this: Docker Hub its github: GitHub - sclaflin/OpenALPR-HTTP-Wrapper: Thin wrapper around the OpenALPR cli program Recently updated.

Those tags are visible in the clips/flagged section, but how do I filter / search them?

Should the video storage disk be defragged every now and then? I could just schedule it to happen during the day, or even better, when nobody's home.

Thank you!!! It is comma and period :)

Where can I find a list of keyboard shortcuts for UI3? I found the docs here but it doesn't seem to mention a list of shortcuts: UI3 Help Specifically I'd like to know how to advance paused video playback by one frame. Currently if I pressed the right arrow, it would jump forward 10 seconds...

Doesn't it need to TRIM or something? EDIT: found a good article about it The real and complete story - Does Windows defragment your SSD?

Learnt something new! I could line the inside of the entire cupboard with this type of material

So far tonight I haven't noticed too much noise from the HDD, so I believe it must've been the weekly automatic defrag. Makes sense. I am usually very sensitive to noise, so I would've noticed it sooner if it was happening all the time. Now all I hear is the constant fan hum, which is fine as...

My LPR camera has other uses...... Can you spot a joey in the pouch (legs hanging out)

If I remember correctly, the HDD bracket has rubber grommets, no screws, and the computer itself has rubber feet. I think being in the cupboard makes it an echo chamber too. But hopefully it was the automatic defrag that made it noisy and now that I've disabled it, I won't have to move it out.

Thanks for the tips. Hmmmmm I just found out that Windows, by default, has a weekly scheduled disk optimisation (as in defrag) and one just ran last night - at 1:48am. I noticed the drive noise at around 10-11pm, so perhaps that's when it started? Anyhow, I've just disabled the check for the...

Hmm... things I didn't pay enough attention to when I first started! There are two models of 8TB, 7200rpm (WD82PURZ) and 5640rpm (WD84PURZ). It seems that the 8TB 5640rpm could be the sweet spot for lower power / noise. I'm contemplating swapping my 10TB WD Purple Pro with my 10TB WD RED 5400...

How/where did you turn it off? I noticed the WD Dashboard can turn off "Windows write caching". Is this the setting you're referring to?

Interesting point about getting a non-pro drive. Quoting from an article: To get 5400rpm I'd need to get a 6TB non pro drive. Interesting to read about >= 12TB being helium filled. Are they quieter than air-filled ones?

I use a 10tb wd purple pro for my blue iris machine on a dell optiplex 7040. It's located in a room adjacent to my bedroom, and at night I find its noise to be a bit annoying. Constantly grinding grr grr grrr. Note that I know what a faulty hdd noise sounds like, and this is not a fault noise...

This will lose the top of trucks / taller cars... would that be OK?

This is my current LPR camera. Should I zoom in more? Other than this particular car, all the other ones can be read very clearly. This one is difficult because it has some sort of acrylic frame over the plate.

Of course not! Knowing this, I'd check for Huma[mn]

Most likely nothing. I want to write some code that deals with the data, and I'm a bit OCD. Why not fix it if they can?

I suspect this typo exists in all their firmware versions since the beginning, just now noticed by someone. I have tested it with: IPC-Color4K-X-3.6MM V2.840.15OG002.0.R, Build Date: 2021-09-08 IPC-T5442T-ZE V2.820.15OG004.0.R, Build Date: 2021-07-29

I was working on getting more detailed IVS data from Dahua cameras (purchased from @EMPIRETECANDY ) and noticed a typo inside the data. This raw data is retrieved using the following command: $ curl -s --digest --user 'user:pass'...

Where can I find the link to 09/08 firmware (or whatever is the latest)? I'm on 07/09 and It seems that ivs isn't working / sending out the trigger
