oh6hfx,
You are using an external switch to connect the cameras, my original question is only about getting push notifications working with Dahua cameras plugged into a Dahua POE NVR as intended by the manufacturer. The external switch solution is the only one that I have found in this forum that seems to be working which is not a satisfactory solution for me being that the cameras were meant to plug directly into the NVR and function correctly.
Hi Keoki,
Sorry, my post was not supposed to be a solution/answer to your original question, just added a post in this same thread while didn't want to make a new one, because problem was almost similar. Just that I did not get push directly from camera, but worked perfectly through NVR.
Now, I am having almost a similar situation to yours here at my home "lab". I have spare NVR4104 NVR with IVS, and four Dahua+Hikvision cameras connected. One is 3 years old Dahua with IVS. I have set up IVS rule in NVR and everything seems to be set just the same way than in NVR4208 mentioned in m yearlier post. However, IVS push notification is not coming through NVR whatever I do. It works perfectly if I subscribe directly to the camera!
I have just same experience than you. IVS rule is tripping nicely, records and even alarm buzzer goes and there is a line in a log, but no push.
I also tested traditional motion detection push. Surprisingly, this works! It's just IVS push that is not working.
