The tool checks one supplied feed. A feed is the video sent by a camera or recorder. The preview supports H.264 video over RTSP or RTSPS, with TCP delivery. H.264 is the video format. RTSP requests a video feed. RTSPS adds encryption. TCP carries the data. Your installer can confirm these settings.
