Thanks! If you model not in supported model list, please write it here, I will add it to the list.
Looking forward for 2 more reviews 
Its possible to receive event for motion detection?
If your VTO support motion detection then probably it’s possible, configure motion detection in VTO, configure integration to record all events and check. You can also turn on debugging and you will see in the log all messages from VTO not only client.notifyEventStream
If integration works for you, please help to get it approved to HACS default repo.

Newbie question here
What’s the benefit of this over MQTT ?
I can’t say that this is benefits, but few points:
Maybe other users here have experience with both versions and will answers better.
Thanks @bar for information that you can use his MQTT or this version of integration not only with Dahua VTO/VTH but also with Dahua Cameras and NVRs.
If you will found something useful, please share it here.
Hello,
Thanks for your job.
I have a vto since 2016 and I am trying to integrate it into my home automation.
but when i put your code i got this message:
“Dahua Vto unavailable”
I put the address of my VTO, the admin user and his password.
is this due to my firmware too old?
can you help me ?
Thanks for your answer
Hello, where you get this message? Please check Home Assistant Log.
If this doesn’t help turn on debug logging and check.
i have this message in my lovelace page
this is my log …

Yes, I think it’s due your firmware too old, because it’s reply to login with empty params. What version of firmware do you have?
You VTO reply:
{"id" : 2,"params" : null, "result" : true, "session" : 1156731805}
Regular VTO reply:
{"id":2,"params":{"keepAliveInterval":60},"result":true,"session":2147483344}
You can try to see if it’s can work at all, replace this line:
self.keepAliveInterval = params.get("keepAliveInterval")
with:
self.keepAliveInterval = 60
If it’s helps and all rest will work as expected, let’s me know, I fix this in the integration.
i changed this line but same result :

Do you know if it is easy to update the firmware ?
In this debug log I doesn’t see protocol messages <<< so I can’t tell you exactly why it’s doesn’t work now, if you give full debug log I can look.
Sure better to keep firmware up to date, it’s not to hard but not straight forward as well. If you have VTH as well it’s will requires more configuration. When I change firmware from 1.0 to 4.3 it’s requares reconfigure everything. First, found and write carrefully version of firmware which you have how and make backup from web interface, if something goes complettely wrong, you will be able to restore. Make screen shots of all VTO settings from web interface.
Find and download latest firmware from Dahua or partners sites, it’s can be a problem, I found firmware for my VTO in FTP: ftp://ftp.asm.cz/Dahua/videovratni
But you can try first the Dahua site
When you will need Dahua Toolbox which you can download here.
I use this video for configuration of my VTO/VTHs and this instruction for updating.
Hope this helps.
Could you send me a MP because i’m newbe and i can’t.
i send you my log
That’s ok for the VTO2000 and VTH1550 firmware 1.0 with the change self.keepAliveInterval = 60
