3.2 Connecting the Camera to the Network and to the Power Sup-
ply
3.2.1 Notes on Cable Lengths and Power Supply
• The power supply of the camera can only be established using the
10BaseT/NET connector of the camera with the (pre-installed) network cable.
In order to supply power via the network cabling we recommend the
MOBOTIX PoE products (MxPoE, see also section 2.12,
Camera Accessories ):
• for one camera using the Network Power Adapter (MX-NPA-3-RJ)
• for up to four cameras using the Network Power Box (MX-NPR-4)
• for up to 8 or 20 cameras using the Network Power Rack (MX-NPR-8/20)
• The maximum length of the network cable for remotely supplying power is
100m (300ft).
• Make sure that you only use switches or routers that support the 10/100
Mbps Ethernet interface of the camera. Check the LED activity of the corre-
sponding port at the switch or router. When operating many cameras, please
also see section 4.11,
Operating Many Cameras , in the Software Manual , for
additional hints.
• It is highly recommended to use uninterruptible power supplies (UPS),
which also protect the cameras and the network components against electri-
cal surges.
• Advantages of MOBOTIX PoE Products:
• Zero maintenance and durable without fans.
• Higher reliability of the system as a whole, since standard routers/
switches without PoE can be used (lower risk of failure).
• Easy installation on DIN rails (
MX-NPR-4 ) or in 19" racks ( MX-NPR-8/20 ).
• If you are using IEEE 802.3af Power-over-Ethernet network components
for supplying power to MOBOTIX cameras, make sure that these compo-
nents 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.
