Yes, we have tested this device with our cameras. What we found out was that the input card would work with cameras, but only using certain resolutions of the camera.
These are the possible resolutions of the PTZOptics cameras. When used with the BMD Decklink Duo 2, we found that 1080p60 will not pull in. We found that all of the PAL resolutions (anything that ends in 25 or 50) do not pull into this device. I am not sure if I missed a setting that would make this accept PAL framerates, but from what I saw it does not. It does pull in all NTSC framrate resolutions with no issue except for 1080p60 and 720p30. 720p30 does not work just because the BMD software does not accept 720p30 as a resolution for the session. So, 1080p30, 1080i60, 720p60, are the resolutions that pull into the BMD Decklink Duo 2 from the PTZoptics cameras.
