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 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 D25M 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):
