2.9 Network And Power Connection
2.9.1 Notes on Cable Lengths and Power Supply
• Power is supplied to the camera via the camera Ethernet connection (patch or instal-
lation 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
Appliances with a maximum total power consumption of 3W may be connected to
the MxBus connector and USB connector if power is supplied to the camera using
PoE class3
. If PoE Class2 is used, the power consumption of all the connected
appliances should not exceed 1W!
For information on changing the PoE class, see Section 2.9.8, «Variable PoE» .
2.9.2 Connecting the Q25M to the Network Using a Patch Cable
Using a patch cable and an MX-Overvoltage-Protection-Box or MX-NPA-Box oers the
following advantages:
• Quick installation/deinstallation
• No shortening of cable even when installing/deinstalling several times
• Hose-proof/dust-proof connection in accordance with IP65
• Additional protection against overvoltages of up to 4 kV when using the
MX-Overvoltage-Protection-Box
Connection of additional
devices with more than
1 W (via MxBus/USB):
