How to get a snapshot from Imou/Dahua cam

Third party integrations Node-RED
1

I like to get a snapshot from my Imou/Dahua IPC-A22E-V2 and send it to my Telegram.
I do have this working for my Foscam camera’s, but I’m not able to get it working with the Dahua.
At my Foscam I do use the GET in http request node using a snapshot url

I try the same for the Dahua, Imou but get it not working.
I used almost all URL’s from this site:
http://www.camera-sdk.com/p_6658-how-to-connect-to-your-dahua-ip-camera-onvif.html

I also tried to use the call service node with domain camera service snapshot
This gives an API error:

EDIT: Is it maybe possible to capture a JPEG out of a RTSP stream in NodeRED?

Any advice will be apriciated

EDIT 2: I did got it working using the camera service snapshot node.
I had to add the entity ID also to the data field in the call service node. It is creating a jpg file which I do send to Telegram

This need to store a jpg file. If somebody knows how to send the snapshot straight without storage would be nice

I had a lot of problems with a Dahua IMOU camera in the past, because it needs an initial setup done by their Cloud Service. As far as I remember you could use a snapshot, but only unencrypted (http instead of https), which might throw errors in HA.

I did some search in my past configs and I came up with this link to get a snapshot:
http://IP:PORT/cgi-bin/snapshot.cgi

Also, I used the Dahua Smart PSS software to manage additional settings.

FYI, in the past I used a curl command in Node-RED to send it to Telegram:

curl --digest --user USER:PASSWORD "http://IP:PORT/cgi-bin/snapshot.cgi"

Thanks for the answer.
For me this url is not working

1 - Just to be sure, you did try http: (port 80)? (instead of https: - Port 443)
2 - What is your browser telling you when using the above URL in your browser’s address-bar?

It is giving 404 error.
I’m not using port 80 I do have port 8081
I did mail the seller, this camera is not having an internal webbrowser
But I do have it running now creating a snapshot using the camer.snapshot service

Yes, you’re right. I did additional config by the Dahua Smart PSS software.

Good to hear! If you need additional info let me know.

If it is giving 404 error, you may need to enable CGI function of the CCTV.
It can be enabled in setting → Network → basic function → CGI
