I bought a DHI-NVR1104HS-S3/H
I immediately updated its firmware. So I don't know how he would have reacted to the IMOU camera at first time, before update.
After that, I connected the IMOU camera to the system and went into SEARCH.
There the system received my IMOU camera. But instead of the PRIVATE protocol, the system in the SEARCH window offered me only the ONVIF protocol.
I waited. Nothing changed. I added this camera by double clicking in the SEARCH list. The camera was added (the passwords on the DVR and the camera were the same)
After that, I added the camera in the "manual add" mode. At the same time, I specified the PRIVATE protocol and port 37777.
I registered the login and password as on the NVR.
After clicking "OK" the camera appeared in the camera line.
But she has a RED dot glowing.
I hovered my mouse over the red dot and received a message:
"Failed to login. Please access the device with ONVIF."
As an experiment, I tried the wrong password. Received a message:
"Wrong username or password"
There are no other protocols in this NVR except PRIVATE and ONVIF.
If you know how to solve this, please let me know.
(Motion detection currently works very poorly.)
