There are 2 kinds of POE device in the market.
One is standard POE which is using 802.3af or 802.3at(POE+). The voltage is usually 48V.
Another is sPOE which doesn‘t support 802.3af nor 802.3at. The voltage is usually 12V.
Only standard POE IPC can connect POE switch, while sPOE can‘t due to technical reason.
some of our systems are standard POE and some are sPOE. Here is the list.
Therefore please check your system‘s model which is at the bottom of NVR. If the model is POE type, the cameras with that NVR can connect POE switch. If it is sPOE type, the cameras with that NVR can‘t and it must be plugged into the NVR directly.
