FAQ: When using the PoEz to connect the switch and camera to perform PoE long-term monitoring and switch to PSE Status, the LED is on. But why does the PoEz screen show no information when switching the toggle to Display?

This can occur on some PoE switches. Mainly due to the PoEz - Power Over Ethernet Detector/PoE Tester needs reaction time. Wait a few seconds to display the value.
