I am having the same issue. Got a Vista Cam PT 2 days ago. With VistaCam SD&PT 1.28 and
VistaCam PT&HD IP Cameras 1.3, it still comes out as a Foscam not a Vista Cam. Can’t get it to work as well. When you go to the cam’s IP, you get a dinky control panel without any settings you can actually control.
I am no camera expert. But I think you could download the plugin files and quickly compare them, then you would sure see the differences pretty quickly.
