To set up streams you need to have a configured device connected to the GUI. If you don't know how to do that, refer to the device setup tutorial.
To set up streams, navigate to device management in the navigation tree, expand the device for which you want to set up streams and double-click video streams. This will open a page where you can configure the streams, select one and click on it, which will bring up the stream settings on the right side in tabs. The maximum number of streams you can configure depends on the version of device you own.
Start by enabling the stream and filling in the name. Choose a descriptive name, as it will be used in notifications, and it will be easier for you to work with.
Next you need to choose the input type. For this you of course need some type of input, so make sure you have a camera connected to the device, or you have some video files on the system. It will be most likely an RTSP stream from an IP camera, so make sure you know the username and password, but you can also choose a USB camera or a folder containing videos. If you choose the RTSP stream, input the link to it. If you don't know how the link should look like, use the help me button. Lastly, enable recording and set the video segment time, we recommend 300 seconds.
Now just press save at the top of the page in header and your stream is all set!
