UDP
UDP is recommended for networks where there is extended latency from one end to the other. The nature of
UDP means that it does not receive a confirmation of each packet being received successfully – vastly improving
performance on distance WANs. UDP can have some consequences f there are other issues on the network such
as jitter or lost packets as it will not inherently re-sent a lost packet.
R-UDP (Reliable UDP)
Reduces overall network load (allowing more NDI streams) by not requiring every packet to be ‘acknowledged’ by
every receiver – has error correction built in for smoothness and reliability.
Multicast
Multicast is especially useful for use-cases that require a single source to be received on multiple receivers
simultaneously. Utilizing Multicast offloads the distribution of the NDI® A/V packets from the camera to the
network infrastructure. You should take care to ensure your network is specifically configured to support Multicast
as using it on an ill-prepared network can create unintended network problems.
NDI® Discovery
If you choose to use a NDI® discovery server, you can configure it in this tab. By default, NDI® utilizes mDNS
(multicast Domain Name System) to create the zero configuration environment for discovery. The primary benefits
of using mDNS is that it requires little or no administration to set up. Unless the network is specifically configured
to not allow mDNS, NDI® sources will be discovered.
The NDI® discovery service is designed to replace the automatic discovery NDI® uses with a server that operates
as an efficient centralized registry of NDI® sources that requires much less bandwidth. Multiple servers can be
specified for failover reduntancy. NDI® discovery server also helps with location of devices that reside on different
subnets. The NDI® Discovery Server is available in the free NDI® SDK .
1. If you are using one or more NDI® Discovery Servers, click the ON button.
2. Enter a comma delimited list of the IP address(es) of your NDI® Discovery Server(s).
3. Click the APPLY button to save your changes.

Password Settings
The BirdUI is secured by a user-selectable password. The default password is birddog (one word, lower case). It is
recommended that the default password be changed, since the BirdUI grants full access to the camera configuration
settings.
You can change the password in the Password Settings tab.
1. Enter the current password.
2. Enter the new password. It is recommended to change this password to retain administration rights to prevent
unauthorized changes. so in a network environment where PTZ Keyboard is shared with other users (e.g. not
private). Confirm the new password and click Apply.
