I've tried all three power supplies (24V ac, 12V dc and PoE) on two cameras. Each time the cameras begin to hum (indicating they are getting power) and I can access them and set them up via the IP Installer software. However, when trying to access the cameras via internet explorer or specific security camera software, no image comes through. While Samsung's tech support responded promptly, all they do is point you to a page in the manual. I've followed the manual with no changes in results. As these are the first security cameras I've attempted to set up, and the problem is with two cameras, it's probably something I'm doing. But it's frustrating as items such as this should be fairly "plug and play" these days.
