Hi,
I have 10 Dahua EZ-IP IPC-D20B20-ZS cameras, and unfortunately It seems your tool gives me an exception:

Exception thrown attempting web request (http://192.168.0.130/cgi-bin/configManager.cgi?action=setConfig&VideoInMode[0].Config[0]=1): The request was aborted: The operation has timed out.

Opening that link on a browser returns a 404 error page (generated by the camera, not the browser)

I tried to sniff the browser data being changed while sapping the Day/Night options via the web interface and I got this:

Message: POST
To: 192.168.0.130:80/RPC2
Authorization: Basic Authentication (user+pass)
Body: JSON with contents: {"method":"configManager.setConfig","params":{"name":"VideoInMode","table":[{"Config":[X],"Mode":0}],"options":[]},"id":0,"session":"528b19ba62cb02611358896"}

Where [X] is 1 or 0 depending on the day or night profile, the session ID its generated somewhere.

Has anyone contacted you related to any API changes? Since I am not able to find the cgi-bin directory.

Thank you so much for the information
