Left Over Vivnt Cameras + ST

The previous homeowner left behind two Vivint branded outdoor cameras and one doorbell camera.

I’d love to use these with ST. Does anyone know if this is possible? If so, how would it be done?

From the other posts I read, it seems that the security-specific gear such as door/window monitors will NOT work with ST. However, I couldn’t find any posts dealing with the cameras.

Any guidance would be appreciated.
