Power-over-Ethernet (PoE according to IEEE 802.3af)

Besides MOBOTIX MxPoE, the MOBOTIX Q22M also supports the Power-over-

Ethernet standard IEEE 802.3af. You can hence use switches or routers that sup-

port the PoE (Power-over-Ethernet) standard IEEE 802.3af.

Sections 3.2 ff

contain more information on the possible combinations of connect-

ing the Q22M and power supply options.

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 a more powerful 19" rack-mounted USP, 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 po-

wer consumption of 3W is very 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 MxPoE products (MX-NPA-3-RJ + external power supply or MX-NPR-4/8/20)

or with PoE-compliant switches according to IEEE 802.3af.

Note

If you are using Power-over-Ethernet (IEEE 802.3af) network compo-

nents for supplying power to the MOBOTIX Q22M, make sure that the-

se components do not have a fan. Since the power consumption of

MOBOTIX cameras is very low compared to other products, the reliabi-

lity of the entire system is increased and the life cycle of the PoE com-

ponents is expanded.
