+The HikVision cameras work best on IE11 browsers, where it will install an active-x plug-in. This plug-in lets you see the live view, and also lets you play the recorded content. HikVision requires that plug-in to be installed to save settings. If you are on Windows 10, just go to run command, and type `iexplore.exe` to open old internet explorer, and go to your camera URL. It will then ask you to install that active-x plugin.
