About the Video Framework hierarchy
The Video Framework network component that is associated with a specific manufacturer's video devices is typically included in the specific ‟Video Driver” palette (not the videoDriver palette) and is available from the Driver Manager view. You can add any video driver that is listed in the New dialog box. (The New dialog box displays when you click the button from the Driver Manager view.)
When you add the video driver component from the Driver Manager view using the New dialog box, the component is placed under the station Drivers node, as shown in Figure 5 Video Framework component in a station.
NOTE: The video driver is, by default, placed at the ‟Network” level. Since it is possible to have more than one video driver network under the Drivers node, it is helpful to maintain this hierarchy for all video drivers in the station.

A video driver, like other NiagaraAX networks, provides a top-level network component for all NiagaraAX types. Under a video network, each manufacturer's ‟device” component represents a particular instance of video hardware. A device component should be located under the manufacturer’s specific video network node, as shown in Figure 6 Video hardware components under the video network.
