Figure 24: PoE power budget information on IP cameras
1. Select the PoE type required for each camera.
2. Dynamic tracking of the current PoE power consumption (blue), unallocated PoE power (white), and
remaining allocated PoE power budget (green) shown.
The IP cameras will specify which type of PoE they require. You can set up each
camera individually for no PoE, PoE-at, PoE-af, 12.5 W or 15 W. A PoE port can
support up to 30 W maximum.
The recorder has a maximum of 8 or 16 PoE ports, depending on the model. The total
PoE power budget for the 8-channel recorder is 120 W, and that for the 16-channel
recorder is 200 W.
The PoE-af port can support between 0 and 15.4 W and the PoE-at port can support
between 0 and 30 W. See Table 12 below for a description of the maximum number of
IP cameras that can be connected depending on the PoE type used.
