No motion events coming from Dahua NVR - Connection to VTO failed

[julet85]

It's popping up hundreds of times in the last few hours. The cameras are working fine but none of the sensors are registering any motion.

Connected to Dahua NVR4PRO with the following cameras:

This error originated from a custom integration.

Connection to VTO failed will try to connect in 30 seconds, error: [Errno 111] Connect call failed ('192.168.1.xxx', 5000), Line: 121

I had a look at thread.py and had a brief look at the code and this failure probably explains why I'm not getting any events from the NVR.

Replying to my own issue.

After doing some searching, I managed to resolve the problem by following the instructions here. The Dahua integration was seeing my NVR as a doorbell.
