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 Manual

, for

additional hints.

• It is highly recommended to use uninterruptible power supplies (UPS),

which also protect the cameras and the network components against electrical

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.
