I really want to be able to cancel the call via ISAPI as well.
Could it be a formatting issue with the command? It says something about unmatched close bracket in column 7. I really don’t understand how ISAPI commands work!
Yes, you are firing from a windows prompt, right? Windows doesn’t like that formatting, try from a Linux prompt, or escape the quotes or send the JSON with a file 
Thanks I tried again using Linux and got the same invalid command message 
indeed, i have asked hikvision, if it is supported at all
Did you try “cancle” instead of “cancel” as it says in the ISAPI capabilities response posted by Virgil_Popa a couple of days ago? Or is that a typo?
Mine gives back “cancel” when I run capabilities 
I tried several, always same error
Oh, got feedback, two-way audio on isapi is NOT supported , probably only with SDK…
Who is a good programmer here?
I may have found something usefull, i’m looking for anyone in here with a Synology running at lease software 6.2.4 … i have xpenology 6.2.3 
seems synology introduced INTERCOM settings, when you upgrade the SS station to 8.2.10 WITH latest device pack update, it seems the KV8113 is listed as an compatible device
Seems the synology can intercept doorpress events, and also can do a door open, i think also two way audio !!! that would be wonderfull
on my work i was able to add mine ds-kd8003 as an 8113 device in synology, but because of firewall rules, i was not able to activate it
but i saw some usefull stuff here!!
Can anyone do it? if this work, we can maybe start tracing how synology is doing this, and maybe use it also in HA
https://www.synology.com/en-global/compatibility/camera?query=kv81
note : you can also add an ds-kd8003 as compatible device, but it doesnt give you intercom functions, specify the 8113 as device
I have latest version of Synology Surveillance Station. Just tried adding my KV-6113 as a KV-8113 but it wouldn’t let me. I got the error message “Some of your settings are invalid”
Hmm, I was able to save it… I’m gonna setup an virtual Synology so gonna try it locally this time
ok, got it running, installed a virtual synology
i was able to access my intercom, i can even open the door from the synology app!! also two way audio was working , i could activate the speaker on the 8003
verry interesting!!
Interesting! Now to try and find out how it does it
I now also got that message, but it was just because of the camera name when you add it, just change it to something generic
Btw @Simon623 , how did you add before the hikvision to your Synology? With just custom camera as an RTSP stream?
Maybe it helps as adding as a generic hikvision camera, or as another type if hikvision camera… Seems hikvision supports two way audio , then it should be enabled in SS station…
Allthough I don’t see a microphone icon in the DS cam on Android
I just added as a generic hikvision camera. It seems the extra features of the KV-6113 are not supported yet.
I can’t add mine 8003 as general, I think it’s because it doesnt support onvif
did some tracing on synology, and not sure how they do it, but their two way audio just works, they use ISAPI
its the only app i have found that actually is able to start two way audio… all others apps that support twoway audio for other brands use onvif or rtsp for backchannel audio
But seems synology did some custom development and they use ISAPI also for start two way audio
but i cant reproduce it, but it most be possible and it works quite good and stable!!
here you can see it:
they also use callstatus isapi too for incoming call events
and some other isapi commands they use for when you activate and load the capabilites of the device when adding it:
ok, some progress
used this man : Dropbox - ISAPI - General.pdf - Simplify your life
i actually got reponse 200 ! means its possible, but not sure how to gu further now
Hi @pergola.fabio , I am also joining this thread now (in the few moments I have to tackle this stuff). Complimenti!
I preface this by saying that my main objective is knowing when the doorbell is ringing and WHICH user/apartment specifically. I have kd8003s.
Anyway, I got an instance of nodered with a previously linked project GitHub - Supergiovane/node-red-contrib-hikvision-ultimate: A native set of node for Hikvision Cameras, Doorbells, Alarms, Radars etc. that looked really promising (it can also hang up as many of you are trying to do from what I see).
I got it to connect but for some reason no status update after ringing the doorbell.
I also just updated the device pack in syno surv station and set it to kv, though too bad that for now no doorbell notification is supported. If there’s anything I can test out please ask.
I may have lost something in the thread, is there a way to know when the door open has been triggered, to then take it and control it with another BMS (so that the built in relay can be freed for increased tamper protection)?
Hey @giangi , thnx for sharing that link, verry usefull for people using nodered!
I had a look, and its based on ISAPI also…
You have a DS-KD8003, well for some reason, there is a lot missing on this device… if you are still on old firmwaren, DONT update to 2.2.50 or later, you cant downgrade anymore
I did a request earlier to hikvision to create a custom firmware for ISAPI support, they included events like unlock door, and call status… the firmware is in first post…
Also, synology will still not work for callstatus, reason, the ISAPI url string is a little bit different, you need to change that in nodered too … see alsofirst post
What firmware are you on?
anyway, of you are already running 2.2.50 or later, then its over and out for ISAPI,you can use the SDK , its much better then ISAPI and faster, and not based on pull, see alspo first thread…
one other question, did you try the hangup command in nodered? does that work for you? I tried the same command, and it doesnt work for me, maybe its because of the firmware
