Key Features – PoE Management

Show PoE Information

  • Connection state of each port
  • Link quality of each port
  • Enhanced signal mode for each port
  • Linked speed of each port
  • Power consumption of each port
  • Total power comsumption

Management Strategy

  • When actual total power consumption is over rated total power consumption, system auto disconnects devices one by one from port N to 1

PoE Bonding

The camera connected to PoE port will be added to the corresponding free channel.
For example, camera connect to PoE port 2 will be added to channel 2 if it is not occupied by other cameras.

Tips: If the channel has been already occupied before, a tip will be prompted to ask you whether change the IPC or not.
