3.3 Connecting the Camera, Power Supply
3.3.1 Notes on Cable Lengths and Power Supply
• The
power supply of the MOBOTIX 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 2.11,
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/
switches 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 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 and the life cycle of these components is expanded.
