FAQ
Q6. The IP camera which connects to the PoE port of the NVR cannot be displayed
automatically in the camera list, why?
a. Please check whether the resource of the PoE port is occupied by another IP camera that is
added through network.

Take the 16 CH NVR with 8 PoE ports as an example. The resource distribution of the 16
CH IP cameras is shown in the picture below.
When you add IP cameras through network, the IP cameras will occupy the resource from CH1,
CH2, CH3, CH4... by the adding sequence; if you directly connect the IP cameras to the PoE
ports of the NVR, the IP cameras will occupy the resource from CH9 to CH16 according to the
number of the PoE port each IP camera is connecting to.
Supposing that 12 CH IP cameras have been added to the NVR through network and no IP
camera has been directly connected to the PoE port. The 12 CH IP cameras occupy the 8
network resources from CH1 to CH8 and 4 PoE resources from CH9 to CH12 which are
supposed to be occupied by connecting the IP cameras directly. In this situation, if you directly
connect one IP camera to PoE5, PoE6, PoE7 or PoE8, the IP camera will be displayed in the
camera list automatically; if you connect it to PoE1, PoE2, PoE3 or PoE4, it won't be displayed
in the camera list by showing resource conflict; if you just need to connect it to PoE1, PoE2,
PoE3 or PoE4, you should first delete the IP camera which occupies the PoE port resource and
then reconnect it to the PoE port.

Take the 8 CH NVR with 8 PoE ports as another example. The resource distribution of the
8 CH IP cameras is shown in the picture below and the adding rules of the IP cameras are
similar to the rules mentioned in the above. Please refer to the above for details.
