Question

What to do if BVMS Operator Client cameo is white and the camera can’t be displayed (device failed)?

Answer

This may be caused by the NVIDIA graphic card driver that might not be compatible.

GPU decoding is supported on specific NVIDIA GPU’s:

− In general, the following NVIDIA Series: Quattro, RTX and T series are supported

− Specific NVIDIA Graphic card drivers need to be used to avoid issues. Therefore, depending on the BVMS version you have, please check the latest BVMS release notes.
