Network switch Requirements for Key Digital AV over IP Systems
Key Digital’s AV over IP systems utilizes multicasting technology to broadcast streams throughout the network.
Key Digital’s AV over IP systems require a network switch with IGMP (Internet Group Management Protocol) support
in order to direct traffic of the broadcasted streams, ensuring that only the desired decoders receive the stream
from the selected encoder.
If the system spans multiple network switches, it is required for the switches to be connected via 10G fiber cabling
for the purpose of stacking. It is recommended to use two of the same model of network switch in these scenarios
for best compatibility.
For 1080p systems (KD-IP1080, KDIP120 models) that plan to use the video preview feature of the Key Digital App,
IGMP v3 must be enabled. For 1080p or 4K systems that will not use the video preview feature, IGMP v2 is enabled.
KD-IP822, 922, 1022 systems require the following IP addresses to be reserved. They cannot be assigned to KD-
IP822, 922, or 1022 units: 192.168.1.1, 192.168.1.50, 192.168.1.90, 192.168.1.100, 192.168.1.150, 192.168.1.200
