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.
l
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.
l
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.
b.
Please make sure that the internal Ethernet port and the IP camera which directly connects to the PoE port through ONVIF protocol are in the
same network segment.
The internal Ethernet port and the IP camera which directly connects to the PoE port through ONVIF protocol should be in the same network segment,
or you will fail to add the IP camera. Log in the IP camera’s web client and then enable DHCP (obtain an IP address automatically); or manually
change the IP address of the IP camera to make it in the same network segment with the internal Ethernet port.
c.
Check whether the number of the added IP camera is the maximum.
If the number of the added IP camera is the maximum, the system will show you the message that the IP camera number is beyond the maximum
when you directly connect another IP camera to the available PoE port and thus you will fail to add the IP camera.
