1. Please give us the spec of the IP camera.
2. Please check if the IP camera supports standard PoE(802.3at/af) or passive PoE.?
3. if it supports standard PoE, it needs to use the 48V power adapter (Note: need to check the power pin of the RJ-45 is Pin4,5,7,8 or 1,2,3,6; our APOE03 use the pin4,5,7,8)
4. If it supports passive PoE, it needs to check the power pin of the RJ-45 is Pin 4,5,7,8 or 1,2,3,6. our APOE03 uses the pin 4,5,7,8.
If the IP camera is IEEE802.3 af/at standard PoE: Use a 48V power supply + APOE03 . A 48V power supply must with a standard DC barrel connector is the best option, for ease of installation.
