Network Requirements
This page summarizes network requirements for both the Windows media server and any controlling devices.
Minimum Internet Speeds
| Use Case | Minimum | Recommended |
|---|---|---|
| Still images, basic control | 10 Mbps | 50 Mbps |
| Standard HD video | 50 Mbps | 100 Mbps |
| 4K video, multiple displays | 100 Mbps | 500 Mbps+ |
A hardwired Ethernet connection is strongly recommended for the Windows media server. Wi-Fi introduces intermittent latency that can affect real-time control and media loading times.
Controlling devices (phones, tablets, laptops) can use Wi-Fi without issues.
Required Ports and Domains
See Firewall & Ports → for the complete list of ports and domains that must be accessible.
The most critical are:
- Port 443 (HTTPS) — core web traffic, API calls, Supabase
- Port 8084 (MQTT over WebSocket/TLS) — browser client command channel
- Port 8883 (MQTT over TLS) — command bus between Vū Studio and the media server
- Ports 49152–65535 (UDP) — WebRTC for camera preview streaming
Corporate / Campus Networks
In managed network environments (universities, corporations, hotels, convention centers), you may need to work with your IT team to:
- Whitelist the required domains on any content filtering or proxy systems
- Open outbound ports 8084, 8883, and the WebRTC UDP range on the firewall
- Ensure the Windows machine is not behind a NAT that blocks outbound UDP
If UDP is blocked entirely, WebRTC falls back to TURN relay over port 443 (TCP) — this works but adds latency to camera preview.
Local Network (LAN) Considerations
The Windows media server and controlling devices do not need to be on the same local network. All communication goes through the cloud. However, being on the same LAN does improve WebRTC camera preview quality since the video can travel directly peer-to-peer instead of through the internet.
VPNs
VPNs can interfere with WebRTC peer-to-peer connections. If you experience camera preview issues while connected to a VPN, try disconnecting the VPN and testing again. MQTT and HTTPS traffic are unaffected by VPNs.
