Dahua IP camera DH-IPC-HFW2230SP can't snapshot

[wittaj]

Make sure you enable the snapshot in the motion detection settings

I solve it.

Changed substream to h26x and then

http://192.168.0.122/cgi-bin/snapshot.cgi?channel=1&subtype=0

works.
But for mjpg it impossible.
It is sad. I can't preview with rtsp withou transcoding on server.

 

[vsw]

Yes. It is a bug.
If substream is mjpeg then snapshot mainstream error.
If h26x then snapshot mainstream ok.

I wrote bug report to Dahua support.
Hope they fix firmware.

SD card needs to be installed as that is where the snapshots are saved!

FWIW, my cams have no SD cards and I get snapshot JPEG's in my Brave browser with any of the first 3 URL's in the first post.

Are you getting the snapshots from the GUI or the API? I think the snapshot function in the GUI will save to your computer but the API is saving to the camera?

But if it works with API then he must not have the local storage set up correctly for it to save to the computer.

The API. Any of the first 3 of his posted URL's with my 841's IP/user/pass bring up the snapshot in Brave:

http://admin:number2020@192.168.0.122/cgi-bin/snapshot.cgi?channel=1

http://admin:number2020@192.168.0.122/cgi-bin/snapshot.cgi?1

Interesting. So maybe the OP needs to configure the local save location?

Good question...my 841 has no storage path, no SD card and FTP and NAS are both disabled....the snap shows up in the Chromium-based browser and is gone if I close it, not saved any where.
All 4 of my 841's act this way, even the oldest version 1.

I need http request. It can be browser/curl/whet or any way.

It works when substream h26x.
It does not work when substream mjpg.

It is a bug.

FWIW, I changed the sub stream in this 841 to MJPG and I can NOT retrieve a snapshot in my browser with the first URL; I put it back to H.264 and it works as it should.
So it is either a bug OR it's by design and Dahau has not documented the requirement that the the sub stream must not be set to MJPG.

Also i have Hiwatch DS-I200, but there is another bug.
Snapshots ok, but mjpg not working.
First run black screen, next "xml responce error 4".
Wrote to Hikvision bug report too.

I am searching camera when rstp h265, http jpg and http mpjg working at same time.

Maybe look for a triple stream camera unless your Hiwatch is triple and still exhibits the same bug.
