User manual

Since the MOBOTIX M12 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.
2.6.1 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 enhan-
ce 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 centrali-
ze 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
MOBOTIX PoE products (MX-NPA-3-RJ plus external power supply or MX-NPR-4/
8/20) or with PoE-compliant switches according to IEEE 802.3af.

PoE components without
fans increase overall
reliability of the entire
system
Note
If you are using Power over Ethernet (IEEE 802.3af) network compo-
nents for supplying power to the MOBOTIX M12, 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.
