At the moment, it is a very simple setup. The cameras run into a switch, which then goes to the router. Dmss is running on my phone, picks up the camera feeds from the router and displays the various cameras. They all appear in dmss, so not a problem with passwords or connection.
Although it shows all of the cameras separately, it will only show the two channels of the dual lens camera in the live multiview. My goal is for all of the cameras to show up on the multiview.
US Dahua support is not helpful. They say the vto is not a US model. I gently protested that the vto isn't the problem, dmss is the problem, and could they please put me in touch which whoever is in charge of dmss, but so far, they're stonewalling me.
