Hi Kinsman Farm!
Since you have several D-link cameras that are IP cameras change to Netcam Studio! Netcam Studio is the next generation of WebcamXP. So I start with your question 3. You get the amount of licenses in NCS that corresponds to the amount paid for WebcamXP. Contact support here http://www.netcamstudio.com/Contact
1.there are so many cameras on the market today so it is impossible to list them all. The D-link DCS-2330L is very easy to add to NCS like this. The camera support 3 different video/audio streams. Go into the configuration of the camera where you can setup resolution for each stream. There you will find this
There you have 3 live streams, live1.sdp to live3.sdp. When you add this camera to NCS use the tab for Custom URL.
-set stream type to rtsp_tcp
-use this address/URL rtsp://username:password@camera-IP:554/live1.sdp
-live1.sdp is video and audio and is usually the highest resolution, 1280 x 720.
2.if you have many USB cameras of the same model webcamxp is a good choice. Otherwise go for Netcam Studio. The other cameras should be in the predefined templates. If not D-link is quite easy to work with.
Good luck and you know where to find me for further questions,
