Коммутаторы
При организации домашней системы безопасности коммутаторы призваны объединять в единую сеть несколько сетевых устройств. Они широко применяются как для создания простейших локальных компьютерных сетей, так и сложных современных систем видеонаблюдения и охранной сигнализации. Функционируют по принципу мостовой технологии.

Описание Dahua PFS4226-24ET-360-V3 24-портовый 100 Мбит/с + 2-портовый гигабитный управляемый PoE-коммутатор

DH-PFS4226-24ET-360-V3 is a type of layer-two managed PoE switch. It provides 24 100 Mbps PoE ports and 2 gigabit uplink combo ports. The full load is 240W.

The product owns powerful network management functions. Network management system supports CLI, iLinksView, web and network management software based on SNMP.

Uplink Combo Port. Two of the uplink ports support a self-adaptive 10/100/1000 Mbps RJ45 port or a 1000 Mbps optical port.

The switch features intelligent PoE power consumption management to help keep the power and data flowing, even when the switch experiences a power fault. Intelligent PoE monitors the power consumption of the connected devices, and in the event of large power fluctuations, the switch shuts down one port at a time rather than shutting down all ports. Unlike typical switches that shut down all ports as once, this switch shuts down the highest number port first, then the next highest number until the switch detects the power consumption is below the PoE budget. Green PoE can power on and power off according to time strategy. It can also realize PoE legacy support.

The red port supports the IEEE802.3bt and the Hi-PoE standards. The maximum power consumption is 90W. Long-distance PoE transmission extends the maximum transmission distance to 250 m (from 100 m), but reduces transmission speed to a maximum of 10 Mbps (from 1000 Mbps).

The switch employs an innovative PoE watchdog function that automatically detects a network port failure and restarts network communication on the port. This functionality avoids manual maintenance and network restarts, saving time and reducing costs.

Intelligent PoE:

• Red port supports 90W IEEE802.3bt

• Web management with friendly interface and easy operation

• 250 m long distance PoE transmission

• PoE watchdog

• Plug and play
