[Streaming PC] ────┘Recommended components
| Component | Recommendation | Note |
|---|---|---|
| Switch | Managed Gigabit | VLANs for separation |
| Cabling | Cat6 | Up to 100m |
| Access point | WiFi 6 (optional) | NDI |
Separate network
For best performance, use a dedicated network for NDI devices, separate from internet traffic.
Option 1: Physically separate
- Own switch for NDI
- No contention with internet traffic
Option 2: VLAN
- Managed switch with VLAN support
- NDI devices in their own VLAN
- Prioritize NDI traffic (QoS)
