1. What is Power Over Ethernet (PoE)?
Power Over Ethernet (PoE) is a technology that transmits power and data simultaneously over Ethernet cables, enabling network devices such as cameras, wireless access points, and phones to be powered over the same cable.
-
2. How to choose a suitable PoE controller?
The selection should take into account the required power, supported PoE standards, input voltage range, operating temperature, interface type (such as RJ45), and whether it has protection functions (such as overvoltage, overcurrent protection).
-
3. How to ensure the safety of PoE power supply?
Choose a PoE controller with overload protection and short-circuit protection, and make sure to use standard Ethernet cables to reduce the risk of electrical failures.
-
4. Is the PoE controller compatible with existing network equipment?
Most PoE controllers are compatible with standard Ethernet devices, but before purchasing, it is best to confirm whether the network equipment used supports the corresponding PoE standard.
