In a scenario where an encoder or network camera can be powered either by a DC12V power source or by Power over Ethernet (PoE). In this setup, the encoder prioritizes power from PoE over the DC12V source. When the encoder is initially powered by DC12V and is then connected to a PoE switch, the PoE source takes over and the DC12V power is turned off. If the PoE power is subsequently disconnected, the encoder will restart and switch back to being powered by DC12V.
This behavior ensures that the encoder or network camera prioritizes the more reliable or preferred power source (PoE) when both power options are available, and automatically transitions to the alternative power source (DC12V) if the primary source (PoE) is lost. It's a common feature in devices that support multiple power input options to ensure continuous operation and reliability.
Is the priority of wired connection higher than that of wireless connection?
Yes, that's right. In a scenario where the encoder or network camera is initially connected wirelessly and you attempt to switch it to a PoE switch, which provides a wired connection, the encoder or network camera will automatically transition from the wireless connection to the wired connection mode by default.
