How do I run the Sentinel remote?

Why doesn't the Sentinel webpage load on my Windows XP computer?


When you use the internet viewing feature of Sentinel, you need to install a remote client which is provided through X10's Sentinel service. To connect remotely, go to in the Internet Explorer web browser on a Windows PC.

When you first open up the website you see a blank, black window while the Sentinel Remote loads.


If you are running Windows XP Service Pack 2, it may show a notice that a download was blocked.


You will need to tell Internet Explorer to allow the Sentinel Remote client to load before the remote client software will work.


  • Click the Information Bar to open the Information Bar Menu.
  • Click "Install ActiveX Control..." to allow the Sentinel Remote client to be opened.

You will then be asked if you want to install a plugin from 'X10 Wireless Technology Inc.' Select "Install."


The remote client is a large file; it may take some time to open depending on your internet connection. Allow the Sentinel remote to load. Once it has, the Sentinel screen shows up in your browser window with a login prompt.


  • Double check that the remote computer is running Microsoft Windows operating system. This and Internet Explorer are needed to view
  • Are ActiveX controls enabled in your web browser? This is necessary for accessing images through
  • Please make sure you are logged in as a Power User or Administrator and have authorization to install or run the Sentinel Remote application. Even though it runs in your web browser, Sentinel Remote installs a small program on your computer.
  • If you are trying to test your Sentinel Server, please be aware that other PCs on the same Internet connection (e.g. using the same DSL or cable connection) may not be able to connect to the Sentinel Server or get video, even if everything is set up correctly.
  • If you are running Internet Explorer 8, you may only see a portion of the browser. If this happens, right-click on that portion and select "Video Size 100%." You should now see the full browser.
