Hi, I'm really new to CCTV in general, so I apologize in advance for how dumb this question might seem. I just haven't been able to find an answer on the web 
I installed the Windows iVMS-4200 Client in Windows 10 Ent x64. I succesfully added the DVR to the devices list and I see the cameras in the Live View, but when I add them, I only see Black boxes, nothing more. I already dragged the camera to each field on the right, but still nothing. I try viewing the cameras from Firefox, and Chome and same behavior.
I can see all my cameras from any iOS & Andriod Device just fine.
Any ideas?
Regards,
