We are doing typically livestreams at hotel conference rooms.
We are using the internet provided by the hotel.

Setup would be 3 NDI PTZ and 1 powerpoint notebook also ingested via NDI.

Do we need a managed switch like the Netgear AV series
or is an unmanaged switch sufficient because of the small setup?

I saw some setups with a router - in which case would we need that?


ps. is there a source where i can see sample setups for NDI and VMIX in hotel/conference environments?

I would highly recommend a good switch/router for your equipment. Do a stand alone setup as if the hotel wouldn't be there and make everything work. If the switch is unmanaged you would need a router for DHCP and routes to the internet and such. Switches are layer 2 and have no idea about IP addresses, routes etc. For switches make sure the switching bandwidth is providing full bandwidth concurrently on all ports. An 8 port 1G switch would need a switching capacity of 8x 1G in and 8x 1G out. So 16G switching capacity.
With managed switches you would want to setup VLANs or multicast for different sort of traffic. NDI, Dante..... Apply a DHCP on the VLAN and create a route to all VLANs so you have internet from the router not only on VLAN1.
Think about your setup in full load. A 1G link can manage 4 Full NDI feeds. If you add more feeds switch to HX or a higher speed link.
I have very good experiences with Mikrotik and Netgear Equipment.
A special focus need to be on the hotel connection. They are usually very poor, unstable and very unreliable, especially at low load (during setup and test) and the event (many people high load) itself. Always have a plan B in terms of external internet connections that ideally are bonded with the hotel one.

In our setup we have a Netgear M4100-24G-POE+ Ethernet switch which we bought second hand.
This links vmix to the cameras and powers them via POE.
It also has some SFP slots so we can use fibre for long network runs if needed.

We also run Dante audio over this switch for commentators headsets, camera operator talkback and audio in to Vmix.
Many will tell you that NDI and Dante should be kept separate and this is almost certainly true if you are using many devices, however after extensive testing of our small setup it works fine for us.

We also use a GLiNet Beryl travel router (latest version here https://www.gl-inet.com/products/gl-mt3000/ ) which is really useful to keep your vmix network separate from the venues network. It will also allow you to quickly swap between Ethernet, WiFi or USB phone tethering for the WAN connection.

Also if I was specifying a system now from new, I would ensure the Vmix PC had at a minimum dual 1G ethernet or at least one 2.5G Ethernet (and make sure the switch supported 2.5G on some ports). 10G Ethernet is getting much lower cost and switches with one or two 10G SFP are quite reasonable (e.g. Zyxel XGS1210-12 or with POE Zyxel XMG1915-10EP, note I've not tried those personally)

The switch needs to support IGMP Snooping, which the Netgear AV switches do, as well as most managed switches. Without that feature, all NDI signals will be sent to all ports, which is probably fine for four 1080p sources, but to be safe, you will want IGMP snooping and at least one 2.5G port for the vMix computer.

I’d also be more comfortable with a router between the hotel network and the switch, to prevent unrelated network traffic from the hotel from hitting your network, and to ensure other hotel guests cannot see your NDI feeds. The routers doesn’t need to be anything special, anything should work, as long as the hotel doesn’t block the use of routers like that.
