3.3 Connecting the Camera to the Network and to the Power
Supply
3.3.1 Notes on Cable Lengths and Power Supply
• The power supply of the camera can only be established using the 10Ba-
seT/NET connector of the camera with the (pre-installed) network cable. In or-
der to supply power via the network cabling we recommend the MOBOTIX
PoE products (MxPoE, see also section 2.11,
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 Man-
ual
, 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 reliable without fans.
- Higher reliability of the system as a whole, since standard routers/swit-
ches without PoE can be used (lower risk of failure).
- Easy installation in 19" racks (
MX-NPR-8/20 ) or on DIN rails ( MX-NPR-4 ).
• If you are using IEEE 802.3af Power over Ethernet network components for
supplying power to MOBOTIX cameras, make sure 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 in-
creased and the life cycle of these components is expanded.
