For those who already have analog cameras, Web Camera Pro also provides the option to convert them into IP cameras using network video encoders. Typically, DVR devices to which analog cameras are connected support relaying them in an RTSP stream, allowing them to be added to the software. The instructions for each camera should specify how to correctly specify the rtsp address for each camera.
Note: The RTSP stream URL is the most important detail you need to add your camera to Web Camera Pro software. You can usually find this information in the user manual of your camera or by contacting the manufacturer.
