Judging by the hashes, my file in the system is absolutely the same as the one you sent.

[Supergiovane]

La stanchezza. Here the right file. Hikvision-config.js.zip

[Sergio-tix]

Yes. Now the snapshot comes in text form. At least part of it. This text is similar to the text that the camera creates in the vault. I allocated disk space to the camera on NAS (CIFS). Set up the camera to take a snapshot when certain events occur. Now she takes pictures and stores them on a network share. And they don't look like a normal picture. It looks like this: File "hiv00000.pic" In which:

And so, one by one, all the snapshots in this one file. When requested through the camera interface, it extracts the image from this file and returns it in normal form with the extension .jpg the output content of the node is very similar to the data in the file. I need some time, I will try to make an image from the text. Thank you!

[Supergiovane]

It seems to mix the jpeg stream data with the camera settings. The content is clearly not an image as i expect. On the ISAPI documentation, there is nothing about the data format. I need to guess it by trying to decode the stream data. I'll let you know...

[Supergiovane]

I have no cameras capable of sending the image embedded into the eventsteam. If you could send me a file (zipped) with the Content-Type: image/jpeg, i will work on that.

I started sending this text data to a file. But somewhere the message is cut off and I get only 20-60KB, when the actual size should be around 400KB.

Here they are. payload.zip

I can offer other information that may be useful. I set up automatic saving of snapshots to a network drive. All information is stored in the file: hiv00000.pic hiv00000.zip In the camera's web interface, saved snapshots look like this:

And these are snapshots if you request their unloading from the camera 2024-09-19.zip If you open the file hiv00000.pic in a text editor, and open the file .jpg in a text editor, you will find a lot in common. It also looks like the text returned in "payload"

[Supergiovane]

There is some extra data in the jpg, that must be wiped out. Thanks for the zip files, i'm analyzing it.

[Supergiovane]

Hi are you able to give me access to the camera, so i can deal with it directly? I need the full event request, with for-data multiparts etc... and i cannot quess it.

[Sergio-tix]

I need to think about how to do this. The camera is on a network that does not have internet access. I access this network through a VPN. I'll come back with an answer a little later.

[Supergiovane]

...or another camera you have on hands, capable of sending the image toghether with the event stream...

[Sergio-tix]

...or another camera you have on hands, capable of sending the image toghether with the event stream...

It wasn't easy for me, but I think I managed to set up my Mikrotiks How can I provide you with information in a confidential manner? email?

[Supergiovane]

Thank you! The connection is working. Now i can work to the payload. I'll let you know.

[Supergiovane]

..just to let you know that i'm actively working on extracting the image from a multipart/form-data message...

[Supergiovane]

...it takes a little long, because i must wait for someone to trigger the event, everytime i do a change in the code...

[Sergio-tix]

You will have as much time as you need. There will be very few events now and they will be rare. Many events happen on weekdays from 12:00 to 15:00 local time. And around 8 am.

[Supergiovane]

Hi Sergio Almost done. Here an image captured by the node.

[Supergiovane]

Hi Sergio node-red-contrib-hikvision-ultimate@1.2.0-beta.1 is out As this is a beta, you need to cd into your ./node-red folder and type npm install node-red-contrib-hikvision-ultimate@1.2.0-beta.1 Let me know if it fits your needs.

[Supergiovane]

1.2.0 official is out.

[Sergio-tix]

This works great! Just what need! Now can get exactly the shots that the camera analytics thought needed, without delay. Thank you!
