Hi everyone ! Usb cameras have proven to be unreliable in low light situations. So I think this new option ... could you advise me and tell your experiences about black and white cctv cameras and if possible in color. What hardware is needed in addition to the camera to get into Isadora? What cables do you use and available length. and if it is compatible with Mac. thank you very much!

[Thanks @DusX ]

best,

You will likely get the best performance (for cheap) with old black and white cctv cameras.. running into some type of capture device.
Most webcams are pretty bad with low light, and have lots of auto focus, brightness etc features built in that can make things difficult.
