Hikvision hi3516cv200 doorbell - interface to go2rtc possible?

[JohannesNeu]

Hi everyone,

I happen to have a Hikvision hi3516cv200 doorbell, that was sold under a different name in my country: AV-Link or HHG Villa.

I am able to access the WebUI, which allows for some MQTT and SIP configurations. But I read about go2rtcs ability to connect to Hikvision devices via ISAPI.

Sadly the ports do not seem to be open on this device, so maybe it is just too old.
ssh access as root is possible, so I was able to pull this information about running programs and open ports:

/proc # netstat -lntup

The WebUI talks about RTMP, but I can only add an address.

Or SIP.

Any ideas how I can figure out how I could possibly integrate this device?

RTMP protocol doesn't support two way audio.
go2rtc doesn't support SIP, yet.

Hi @AlexxIT

I think RTMP not supporting two way audio is something I have to accept, but being able to forward the video streams would be a win nonetheless.

About, SIP, yes implementing a whole new protocol looks like a lot of work.

Is there any way to figure out from the ports alone or the first screen whether ISAPI is provided by this device or how RTMP would need to be configured on either go2rtc or the doorbell?

Sadly there is no manual, I don't even know if the rtmp box needs an IP in the first place

[AlexxIT]

ISAPI probably works over 80 port: https://github.com/AlexxIT/go2rtc/tree/master?tab=readme-ov-file#source-isapi
RTMP: https://github.com/AlexxIT/go2rtc/tree/master?tab=readme-ov-file#module-rtmp
