then its normal that it doenst work in HA also
see first post , there are some examples
i dont know the 81xx model, but maybe you need to enable rtsp first?
But this rtsp://user:[email protected]:554/Streaming/Channels/101 work ok and i test it in VLC player.
ok, then use that one?
ok but what with still_image_url: ?
if you dont have a still image url, then create one 
use the snapshot feature with an automation to make snaphots every xx sec with the same filename in your local HA directory, then use that url link as your snapshot url
or install motioneye addon, import the camera there with rtsp stream, motioneye will give you then a still image and stream urls
sorry please explaine me more… i am beginner…
Have a look here:
You can always create a new topic on community, let this thread for isapi info, not for generic questions 
@pergola.fabio is there anything that needs to be enabled to connect to ISAPI?
This is my output:
~ $ curl -i --digest -u admin:xxxxxxxxxx http://192.168.188.100/ISAPI/VideoIntercom/callStatus?format=json
curl: (7) Failed to connect to 192.168.188.100 port 80: Connection refused
I ran Fing and couldn’t find port 80 open:
However port 80 seems to be configured via iVMS-4200:
Not that i know, i only have the 8003 system, not sure about others
I have DS-KD8003 too
Then it should work, i didn’t have to enable anything…
But the call status command always gives idle status , so not usable yet on a 8003, will be fixed in newer firmware
I know, I just want to start familiarizing with the ISAPI for the time being. According to Fing my unit is not listening to port 80, see previous screenshots
Verry strange, what firmware are you running?
2.0.8 build200701 that was installed by the supplier, who also discouraged me from installing firmwares downloaded from internet
Mine is newer
@pergola.fabio What firmware version are you using?
I have installed V2.2.3 build 200805 and the “CallStatus” doesn’t change to “ring” 
.
same here, on the kd8003 its a firmware bug, a custom new firmware is coming , i think within 2-3 months, so we need to wait for that function
just confirming that the callStatus doesn’t work on a DS-KB6403-WIP
Streams so work though, been using them for a long time with project motion
which version and build are you using?
Who share custom firmware for HikVision ?
