Model InfoOT Systems ET4222PpH is an etnernet switch that support IGMP with a simple click of a dip switch. In large IP CCTV surveillance systems, IP cameras employ multicast transmission to reduce the needed bandwidth. However, an unmanaged Ethernet switch is poorly equipped to receive multicast packets; it converts them to broadcast packets. The system then sends broadcast packets to every port in the switch resulting in video loss or disconnection. OT Systems has eliminated that concern. By simply changing the dip switch, the ET4222PpH efficiently receives multicast packets and only forwards the data to the appropriate port. This innovative feature saves bandwidth and maximises the switch performance, increasing the systems effectiveness and reliability.
