2.9.8 Variable PoE
The power consumption of the camera depends on the functions in use as well as any
peripheral devices connected (see table). PoE classes 1, 2 or 3 may be selected in the
browser-based user interface in order to optimally adjust the camera to your system
design (PoE switch in use, emergency power concept, etc.).
PoE Power Level Classes (IEEE802.3af Standard)
Class Max. power consumption Camera operating mode and peripheral devices
1 0.44W–3.84W
LowPower mode; no peripheral devices (available
soon)
2 3.84W–6.49W
Normal mode; max. 1W for MxBus peripheral
devices
3 6.49W–12.95W
FullPower mode; max. 2.5W for MxBus peripheral
devices (for example, MX-GPS-Box and MX-232-
IO-Box to MxBus), max. 4W for peripheral devices
to MxBus and USB interface
Caution
If the total power consumption of the camera and peripheral devices exceeds the
power provided by the PoE switch for the specified class, the switch can disconnect
the camera from the power supply.
In this case, the camera will only be accessible
again once the peripheral devices have been disconnected from the camera and
the camera has been restarted.
The default setting is usually fine, and nothing needs to be changed. However, the PoE
power class must be changed in the browser if a higher or a lower power class is required
for your application:
1. Select Admin Menu > Network
Setup > Ethernet Interface (for
experts).
2. Click on Change under Power
Supply.
3. A Power Wizard will appear to
guide you through the PoE con
-
figuration steps.
4.
Next, restart the camera: Disconnect
the camera from the power supply.
Then reconnect it, for example, by
disconnecting and then reconnect-
ing the Ethernet cable at the PoE
switch.
Variable PoE:
Multiple cameras
can be operated
simultaneously from
the same switch
