If you are running Win 10, it may be a security issue, as it may want to install an activex component to your browser. I had to turn off some of the security measures in IE before it would install. The activex component gives you the ability to see the cam live and adjust hue, sat, sharpness, etc, along with changing the motion detection area.
I can also access it via Linux, which is my every day OS, but this limits me to just changing simple menu options and not the motion area settings, etc.
Maybe Gus13 can chime in and tell you how he did it, or contact LaView support.
