When I have a look at the manual I think 15 days is not very much time for trying . Thanks at all I will try it:thumb:. But you can be sure that I will have many questions.

I thought about getting information about Events from BI. But that's not interesting for the current project and offtopic. I'm just asking out of curiosity. I think I found a possibility here: Simple Blue Iris I/O using Shelly1 Wi-Fi Devices and here Blue Iris controlling home automation I've...

Has BI an API or something like that?

Yes I think that's the way I will go. That's no nice solution... When the hardware requirements for blue iris are so low it could also be a good solution. Thanks for your help :thumb: !! I think now I know in which direction I can go.

Ok thanks:thumb:! I will have a look. Yes I thought so, too. But then I've to buy an PC with the hardware and software. I think it would cost much more then an NVR and it would need more electricity. In my usecase I only need three cameras with motion detection so that would be to much I think...

Basic MD would be enough for my usecase. Which NVR do you use?

Do you know a NVR which can handle manufacture independently cameras? It should has at least an analysis function for motion detection.

I can't find it anymore, but somewhere i read that motion detection is necessary for using perimeter protection. But the NVR can't handle motion detection the cameras have to do that. But the cameras aren't from Hikvision so that could be a problem. Anyway, I suspect that the problem is that the...

I just tried Auto setting but it seems that the nvr recorded continuously. In the Alarminformation no Alarm appears

Yes I think you mean thiso_O

I'm not really sure what you mean. Do you mean this?

I have a HikVision NVR DS-7604NXI-K1 (FW: V4.73.006 build 221108 [Edit: new FW: V4.75.005 build 230630]) with two default (not Hikvision) ONVIF-Cameras. I want to create a perimeter protection Event (e.g. region entrance detection). The VCA-mode is by NVR. I draw a region on the hole picture...

Thanks for the mass of information. But I've a few questions. The picture should help to understand my questions: Why should I use a Router as a VPN-Server instead of using a VPN-Server behind the Router? I see that I should put the NVR in a Demilitarized Zone. But is it OK to put the cameras...

I don't think that you need to open more then one port for rtsp. Did you try to use the Http-Port (93) for rtsp?

I don't really understand your problem... Where did you try the link? In your Browser?

I've the solution now. It works with /ISAPI/Streaming/channels/2/picture. But I had the wrong Firmware, so it didn't work or me. With the correct Firmware it works.

I can't run this script... I don't know why i've never worked with go... but i saw that the datafield should be converted in uint32 datas (in my case). I try to write a bash script which does this. But for the next two weeks I've holiday I think then won't happen very much. After my holidays I...

No I don't think so... I removed the head inclusive the first --boundary-part and could the file open as a picture. Now i tried it but I don't know how to convert from octet-stream to .jpg.

Ah Ok I could't see it good on the picture... i thougt that was an good working example.... No I think the idea with ffmpeg is until now the best...thank you for your help :thumb: I will try how hard the delay is. I think I can run bash-commands in my c++-application. So it wouldn't be...

I'm not realy sure what you mean... do you mean i should use ffmpeg to get the screenshot? which plugin should be loaded where? Why have the ISAPI the data in your case? I'm not realy sure whether i did it right, but i removed the head of this file (in the head are no temperature values) and...

then i don't know what wrong... that's my result: and that's my adjustments (sorry that it is german i don't know where to change the language) and that's a screenshot from the rtsp-Stream.... here it works

of course I'm thankful for your help! Yes I know this works but I need more than 4 Fields... No, unfortunately not...

If there is no other solution I will write an application in the background, which makes a screenshot from the rtsp-Stream. But this would have at least 2 sec. delay.

That wouldn't be enough I've up to 10 Temp. measuring areas with max., min. and average temperature. Plus the lines of the areas...

Do you mean to PUT /ISAPI/System/Video/inputs/channels/overlays/text/ to overlay the temperature values? Is there an other method to get a screenshot? I'm using c++ on a very old compiler so using the rtsp-stream is a big problem....

thanks but this doesn't work.

I get a screenshot from my thermal camera (DS-2TD2628-3/QA FW:V5.5.64 build 221212) via ISAPI with the url /ISAPI/streaming/channels/101/picture. But no temperature data are displayed on the picture. In the stream they are showed. Is it possible to get a picture with the temperature datas?

new understanding: With an IR-LED I could see that you get the temperature value, measured a short time after sending your request, in the following answer. The value, which is approx 50ms after sending the request in front of the camera, could be received in the next answer or in the following...

thanks for your help:thumb:. Now I have it with digest authorization. It works like ChatGPT said and as it is written in the link. Nonce, realm and qop is created by the server (here camera) and the rest is created by the client. I resume it if somebody has the same issue and finds this here:D...

I'm trying to implent the ISAPI request over http in Structured Text in TwinCat 3... but for that I've to generate the response in the Authorization-Field. The authorization method is digest. I find a algorithm here RFC7616 but i don't get the correct result. Do you know the correct algorithm?
