2.7 Network and Power Connection
2.7.1 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 four watts may be con-
nected 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 one watt!
For information on changing the PoE class, see
Section 2.7.8, «Variable PoE».
2.7.2 Network Cabling For M25 With Patch Cables
Using a patch cable and an MX-Overvoltage-Protection-Box or MX-NPA-Box offers the
following advantages:
• Quick installation/deinstallation
• No shortening of cable even when installing/deinstalling several times
• Hose-proof/dust-proof connection in accordance with IP66
• 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):
Max. ambient tempera-
ture +50°C/+122°F!
