Network and Power Connection
2.7 Network and Power Connection
• Power is supplied to the camera via the camera Ethernet connection (patch or installation
cable). We recommend using a MOBOTIX PoE adapter or another similar high-quality
PoE product to loop-in the power supply:
– One camera: with the PoE adapter (MX-NPA-PoE or MX-NPA-Box)
– Multiple cameras: with PoE products conforming to IEEE 802.3af (PoE switch)
• The maximum length of the network cable for power supply over an Ethernet cable
is
100 m.
• Make sure that you only use switches or routers that support the 10/100Mbpsnetwork
interface of the camera.
• We highly recommend using uninterruptible power supplies (UPS) to provide backup
power.
• If you are using IEEE 802.3af or IEEE 802.3at (PoE+) Power-over-Ethernet network
components to supply power to MOBOTIX cameras, make sure, if possible, that these
components do not have a fan. Since the power consumption of MOBOTIX cameras is
very low compared to other products, the reliability of the entire system is increased,
thus extending the life of these components.
Caution
Max.powerconsumptionofattachedextensionmodules: The power consumption
of all attached
MxBus modules must not exceed 3 W . When attaching modules to
the MxBus connector
and the USB socket, the power consumption of all attached
modules must not exceed 4 W , if the camera is powered by PoE class 3 . If PoE class 2
is used, the camera cannot power any peripheral devices!
For information on changing the PoE class, see Section 2.7.5, «Variable PoE».
