Make sure that you only use switches or routers that support the 10/100 Mbps
Ethernet interface of the camera and check the LED activity of the corresponding
port of the switch or router. For additional information on this topic, see section 4.11,

D12 Camera Manual Part 1
Notes
The MOBOTIX D12 can only be powered using the 10BaseT/NET
connector of the camera. In order to inject the power supply into the
network cabling, MOBOTIX PoE products have proven reliable and
easy to install for one camera (MX-NPA-3-RJ), for up to four cameras
(MX-NPR-4) and for 8 or 20 cameras (MX-NPR-8/20; see section
2.10,
Optional Accessories ).
It is highly recommended to use uninterruptible power supplies (UPS),
which also protect the cameras and the network components against
electrical surges. For more information on this topic, read section 2.3.5,
Using Uninterruptible Power Supplies (UPS) .
Maximum Cable Lengths (Ethernet)
Data/power connection: max. 100 m (110 yards)
Use the MOBOTIX MX-
NPR-4 Network Power
Box for smaller installa-
tions
Use the 19" MOBOTIX
Netpower rack-mount
units to supply power to 8
or 20 cameras (MX-NPR-8
or 20)
Uninterruptible power
supply (UPS) should be in-
stalled
