A. Enabling the Multicast Function
The Multicast Function is a technique for one-to-many communication over an IP infrastructure in a
network that is designed to share IP camera loading and reduce network bandwidth. Note that for this
function to work, the router / switch must support multicast function.

2. Access to the Web UI of the IP camera to enable the Multicast function. Click the Save button to save
the setting. (System > System Settings > Network > Multicast Settings > Enable Multicast)
