2 x HD dome cameras
( 9 W +2.5 W) x 2 = 23 W
1 x HD PTZ camera
25.5 W + 4.5 W = 30 W
1 x HD micro dome
4 W + 2.5 W = 6.5 W
Total
= 59.5 W
The total power consumption of the 4 cameras is within the PoE switch component limits.
NOTE:
If you miscalculate the required power for a PoE port, the connected camera may be shut down if total
power output exceeds 61.6 W.
Assigning a PoE Power Budget
On the POE page, the first row is for Port 1 and the other ports are listed in order from top to bottom. On the
recorder, the ports are listed in order from left to right.
You can assign PoE power budget in the following ways:
Option
Description
Disable power output for a port
From the Power drop down list, select
Off
Once disabled, the port no longer outputs power but can act as a
standard network connection for any device.
Tip:
You can also use this feature to remotely restart the camera. After
you set the Power setting to Off, wait for the camera to power off then
change the Power setting to
On
.
Disable PoE Plus on the ports that are
connected to standard PoE devices.
From the POE+ drop down list, select
Disabled
.
Once disabled, the port only supports PoE 802.3af with 16 W of
maximum power output.
Manually assign a specific PoE
budget.
In the Budget column, enter a power budget value in watts. Make sure
the budget includes potential power loss at the cable. For more
information, see
Budgeting PoE Power
on the previous page .
When you click the
Budget
field, the following note is displayed:
Note: Set to maximum power. Refer to the user guide for guidance.
By default, the Budget field budgets a maximum of 30 W when the POE+
setting is Enabled, and 16 W when it is Disabled. Depending on the
POE+ setting, you can enter any value within the maximum power
budget.
Revert to the factory default settings.
Click
Restore Defaults
.
The factory default settings are:
l
