This is interesting. My CMSClient has never been able to connect to get the IP information. I used the Yoosee app before I tried the CMSClient, so it might have set a password then.Thank you. It's 有 and it means 'have'.
The strangest thing happened yesterday: whenever I start the CMSClient software and try to obtain the IP config it always comes back with 'password error' but one time, and one time, it suddenly did return the IP config and I was also able to click the Password button and set a new password. After that the IPCTestTool showed the same Chinese character as in your screenshot.
Not that it made any difference. I was still unable to see any of the ONVIF details in ONVIF Device Manager (v 2.2.250) for instance. At some point I rebooted the camera in IPCTestTool and it wouldn't come back on so I did a hard reset on the device itself. After the 'hass password' column in IPCTestTool was empty again.
Anyway, it looks as if I can get the videostream from the device without setting a password. This works in BlueIris, IPCTestTool and contrary to what I said before also in CMSClient because I found out that if I double-click the manually added camera it does show the video stream from it.
I also tried setting the password today from IPCTestTool with the 制 作 烧 录 文 件 popup menu entry but that doesn't seem to work.
I did capture the network traffic when I was setting the password with CMSClient but it's not easily decodable. At the moment I cannot do any further experiments because CMSClient is refusing to start and I don't want to reboot the PC remotely (it's at the office).
When I get back there I will reboot and continue my experiments. One thing I want to do is setup a mirror port on my switch and capture all traffic between the camera and everything else to see if there is something it tries to connect to when pressing the doorbell, although it's quite possible it will only try to do that after setting a password or after it has already connected to the cloud server.
How are you doing a hard reset on the device?
