Try the following connection options in iSpy to connect to your Revotech IP camera. If VLC or FFMPEG options are available we recommend you try those first as they will often be faster and include audio support. If you don’t have VLC installed (or are experiencing problems with the VLC plugin) you may be able to use the same URL under the FFMPEG source type (VLC is based on FFMPEG).

The settings for Revotech cameras are built right into our open source surveillance software iSpy – click “Add” then “IP camera with wizard” to automatically setup your Revotech cameras. Start typing in the “Make” box to find your camera. If your camera is not listed in iSpy then click “Get Latest List” when on the add camera wizard. If you need to modify the URL then add or edit the Revotech camera in iSpy and you can modify the connection type and URL in the video source dialog (button is top of the first tab).
