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
PoE adapter or similar high-quality PoE product is recommended to provide the
power supply via the network cable (see Section 2.3 Available M24M Accessories ):
• one camera: with the PoE adapter (MX-NPA-PoE)
• 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
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 backup
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.
2.9.2 PoE Variables
The power consumption of the camera depends on the functions in use as well as any
connected expansion modules (see table). PoE classes 1, 2 or 3 may be selected in the
browser-based user interface in order to optimally adjust the camera to your system
design (PoE switch in use, emergency power concept, etc.).
PoE power level classes (IEEE 802.3af standard):
Class Max. Power Consumption Possible Operating Modes
1 0.44W – 3.84W
Normal operation without audio output and without
USB devices
2
3.84W – 6.49W (factory
default)
Normal operation with audio output and with
USB devices
3 6.49W – 12.95W Like class 2 and also with MxBus devices
MOBOTIX
factory default
is class 2
