The manual is located at this link
The camera works with the Plug & Play application,
there they perform the camera streaming over IP or WIFI, , but I have
not been able to open with the webviwer the IP address or through some URL
In WIFI mode, the camera is accessed as any WIFI network, searching the MD81S network with the password 12345678(Manual information), then you enter the application and in the LAN mode (Plug & Play) you can see the camera streaming (image 1)
In IP mode, the camera must be connected to a
modem, then in the application in WAN (Plug & Play ) mode, the user and
password of the manual are entered and finally you can see the camera streaming

I know the IP in both cases but when I put it on the internet it does not show me anything, I do not know where to reference the Webviwer
