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.

Note: The PoE power specifications are the PoE power available at the recorder.

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.

To display the PoE power consumption information:

1. From the menu toolbar, click Camera Management > Camera > PoE Setup.

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.
