Applies to: All PoE NVR
There are 2 kinds of POE security systems in the market.
One is the standard POE which is using 802.3af or 802.3at(POE+). The voltage is usually 48V.
Another is the sPOE which doesn't support 802.3af nor 802.3at. The voltage is usually 12V.
Only standard POE IPC can connect POE switch, while the 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 number which is at the bottom of NVR. If the model is a POE type, the cameras with that NVR can connect to the POE switch. If it is sPOE type, the cameras with that NVR cannot connect to the POE switch and it must be plugged into the NVR directly.
