In this presentation, we’ll guide you through what to consider when looking at an NDI friendly switch. There a lot of considerations that you need to take into account when you are setting up a IP based video production system because everything leverages your network switch. In this video, we break down all the common considerations network engineers are thinking about when they are building a local area network for video production. When we talk about IP-Based video production we are commonly referring to video sources made available for software based switcher like Wirecast, xSplit, OBS or vMix. The Two BIG Points for Consideration- The switch must be at least Gigabit The switches must accommodate mDNS “Ideally, the switches also will accommodate multicast with IGMPv3

2. Finding a Compatible Switch
You’ve just purchased your PTZOptics NDI|HX Cameras. YAY! The fun,
however, doesn’t end there. It’s important to have the proper network switch, to
ensure smooth performance and optimization with your new system.
In this presentation, we’ll guide you through what to consider when
looking at an NDI friendly switch.

3. Recommendations From Our Lead Engineer
Two BIG Points for Consideration-
“ The switches must accommodate
mDNS”
“ Ideally, the swithches also will
accommodate multicast with IGMPv3”

4. Network Switch Considerations
➔ Gigabit Ethernet * Required*
◆ But no more than a gigabit
➔ Full Throughput Switch Backplane *Required*
◆ Capacity = # of ports x speed x 2
➔ DHCP Recommended
◆ *Required* for NewTek control panels connected via
ethernet
➔ For Devices That Optionally Support PoE
◆ PTZOptics NDI|HX Cams require PoE (15.4w)
◆ NewTek Connect Spark requires PoE (15w)
◆ Note* PoE+ supports PoE but PoE doesn’t support PoE+
◆ Make note of the power needed for devices/switch

5. Managed Switch Settings
➔ Disable Quality of Service
➔ Disable Jumbo Frames
➔ Enable Flow Control as Asymmetrical of Simply as On
➔ Enable IGMP Snooping if Using Multicast (mDNS)
➔ Configure IGMP Querier and Query Interval Per Switch in Multi-Switch
Networks (While Using Multicast)

6. Firewalls
➔ mDNS must be accessible
➔ Manual discover requires access to port 5960 for messaging and all
coming after 5961 for streams
➔ Check the port range from Microsoft PC’s using Cmd: ntsh

7. Cabling
➔ Minimum of CAT5e cabling required for GigE
VLAN Deployment
➔ NewTek asks that you contact them directly for VLAN deployment
options

8. Network Adapters
NE➔ Use DHCP to assign IP addresses or assign
static manually
➔ Use manual configuration in NDI Access
Manager to cross subnets
➔ Designate network location on all NICs as Work
(private)
➔ Connect and available Gigabit + network
interfaces
Network Latency
NE➔ Full circle latency must be <14ms
➔ NDI v3.5 supports UDP with Forward Error
Correction for unicast (prior versions use TCP)

9. Bandwidth Requirements (Approx)

10. More Tips from NewTek
“Confining your NDI® workflow to a dedicated or uncontended network is highly
recommended for management, reliability, and troubleshooting purposes—
especially if migrating to an IP workflow for the first time.”
“ NewTek Professional Services can help you achieve your ambition, regardless of
scale or complexity—engage us early on to ensure your success!”
