User manual

Since the MOBOTIX D12 supports Power over Ethernet (IEEE 802.3af), you can
also use PoE switches or routers for supplying power. Section 3.2, Connecting the
Camera to the Network and to the Power Supply
, contains more information on the
possible combinations of connections and power supply options.
2.3.5 Using Uninterruptible Power Supplies (UPS)
In order to maintain a continuous power supply even when utility power fails, you
should install an uninterruptible power supply (UPS). These devices also provide full
protection against electrical surges and voltage fluctuations and thus enhance the
reliability of the system as a whole.
When using more powerful 19" rack-mounted USPs, you can also protect all other
network components (e.g. switches, routers, PoE switches, etc.).
Since MOBOTIX cameras do not require any heating even in the wintertime, the
power consumption of 3W is quite low. This in turn means that you can centralize
the USP-protected power supply by injecting power into the network cables (max.
100m/300ft). This kind of protected power supply can be used either with MO-
BOTIX PoE products (MX-NPA-3-RJ + external power supply or MX-NPR-4/8/20) or
with PoE-compliant switches according to IEEE 802.3af.

UPS not only protect the

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, the reliability
of the entire system is increased and the life cycle of these compo-
nents is expanded.
