Often folks buy unbranded cameras or cams that are not popular and therefore not on the blue iris drop down list. If you wish to use these cameras with blue iris here is a great video I found showing how to find the rtsp stream using onvif device manager-a free tool, and how to properly enter it into blue iris. ONVIF Device Manager Blue iris now also offers a find/inspect function for onvif cameras. Enter the ip address and correct credentials and if the camera is onvif it should find it. You can also find a list of url's for many cameras here. Connecting iSpy to IP Cameras You can still use the video to learn how to properly enter the urls from ispy's site into blue iris. Finally, some mobile apps like ipcamviewer by Robert Chou or tiny cam (android only) have a scanner that will identify the camera and will often list 3-4 compatible cameras, one of which my be on the blue iris list. If none of these work contact the developer at www.blueirissoftware.com Note there are errors in the video...blue iris obviously supports more than 720p..
