2.4.6 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 po-

wer 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 MOBO-

TIX 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.
