# Setting Camera Transport Protocol

Navigation: Working with Nx Witness > Device Management (Cameras, Encoders and I/O Modules) > Setting Up Cameras and Devices > Working With Expert Device Settings > # Setting Camera Transport Protocol |

By default, Nx Witness automatically determines which RTP media streaming protocol to use for a camera: UDP (faster, but less reliable) or TCP (more reliable, but slower). However, sometimes a camera may have issues streaming via the automatically selected protocol. If that is the case, you can manually set the RTP protocol as follows.

IMPORTANT: Do not change these settings unless you are absolutely sure of their potential impact on your system performance.

1.Use the camera's context menu to open Camera Settings -> Expert.

2.In the RTP Transport menu select TCP or UDP.

3.Click Apply, OK or Cancel.
