Hi @supergolfstick, RTSP stream is not supported in web browsers, and, therefore, the camera stream must be converted to JPEG/MJPEG to be displayed in the dashboard. I have not tested Unifi cameras personally, but based on my quick research, you can get the JPEG image from the camera by accessing http://camera_ip/snap.jpeg.
Once you verified the JPEG image can be accessed via the web browser, you can then create a Media resource, and set it to auto refresh periodically, and then add this media to your dashboard to view the camera image.
Or if you prefer the real-time streaming camera views, instead of image refresh every few seconds, you will need something like Blue Iris or TinyCam to convert the video streams to MJPEG and proxy the video streams. You can find more details in the KB article below.
