2.4.5 Selecting the Power Supply
In order to reduce the amount of cabling, you should always use the Ethernet cable
(NET/10BaseT) to inject power into the camera cabling (Power over Ethernet).
For smaller installations, the MOBOTIX Network Power Adapter
MX-NPA-3-RJ
and
the universal power supply
MX-SNT-E/U/GB/J/AUS01-30-RJ
is sufficient. Larger in-
stallations would benefit from one or more MOBOTIX Network Power Boxes/
Racks that are available for supplying power to 4, 8 or 20 cameras (
MX-NPR-4
, -
8
or -
20
). See section 2.3,
Camera Accessories
, for more information on these and
other items or open shop.mobotix.com (Products> Accessories section).
Since the MOBOTIX D12 supports Power over Ethernet (IEEE 802.3af), you can
also use PoE switches or routers for supplying power.
Section 3.3,
Connecting the Camera
, contains more information on the possible
combinations of connections and power supply options.

Advantages of the MOBOTIX PoE Products
• Zero maintenance and reliable as the systems do not require
fans.
• Higher reliability of the system as a whole, since standard swit-
ches without PoE can be used (lower risk of failure).
• Easy installation on DIN rails (
MX-NPR-4
) or in 19" racks
(
MX-NPR-8/20
).
Note
If you are using Power over Ethernet (IEEE 802.3af) network compo-
nents for supplying power to the MOBOTIX D12, make sure that these
components do not have a fan. Since the power consumption of MO-
BOTIX cameras is very low compared to other products, this increases
the reliability of the entire system and expands the life cycle of these
components.
