2.9 Network And Power Connection
2.9.1 Notes On Cable Lengths And Power Supply
• Power may only be supplied to the camera via its Ethernet connector. A MOBOTIX
Power Adapter or similar high-quality PoE product is recommended to provide the
power supply via the network cable:
–
one camera:
with the Network Power Adapter (MX-NPA-PoE)
–
multiple cameras:
with quality PoE products conforming to IEEE 802.3af
• 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
Ethernet interface
of the camera. Check for LED activity on the corresponding port of
the switch or router. When deploying several cameras, read the notes in
Section 4.11,
«Operating Multiple Cameras» in the Software Manual.
• It is highly recommend to use uninterruptible power supplies (UPS) to provide back
up power.
• If you are using IEEE 802.3af 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 2.9.8, «Variable PoE».
2.9.2 Connecting the D25M to the Network Using a Patch Cable
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 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):
Max. ambient tempera-
ture +50°C /+122°F
