# Ncam

LightAct supports both **TCP** and **UDP** versions of this protocol. User also needs to enter the **Server address**, which is the IP address of Ncam running server.

### Ncam Receiver Device Node

To start receiving Ncam information insert a **Ncam Receiver** device.

On the right side, under the *Stream*, configurable properties for specific devices will be shown. After you configure them, check **Listen** checkbox inside the device node.

### Read **Ncam** in Layer Layouts

To use the information read by **Ncam Receiver** node in LightAct, you need to create a **Read Ncam** node in the layouts.

Choose **Ncam Receiver** device in a **Device** dropdown menu, or connect **Device reference** node to this input, and you are ready to go.
