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 19 below for a description of the maximum number of
IP cameras that can be connected depending on the PoE type used.

However, depending on the cable length and cable quality you can experience a loss of
PoE power. Ensure that this is taken into account when configuring the system.

2. Select the PoE type required for each camera: No PoE, PoE-af, PoE-at, 12.5 W or
15.0 W.
3. Click Apply to save the settings and then click Back to return to live view.
Automatically allocating PoE power
The recorder can be set up to automatically allocate PoE power depending on each
camera’s needs. Note that if the full PoE budget (120/200W) is used on the first seven
ports, for example, PoE port 8 will no longer be powered.
To set up auto PoE:
1. From the menu toolbar, click Camera Management > Camera > PoE Setup.
2. Check Auto PoE.
3. Click Apply to save the settings and then click Back to return to live view.
