APPENDIX C: POWER OVER ETHERNET
APPENDIX C
Power over Ethernet
Some SCBlack cameras and encoders support Power over Ethernet (PoE) in conformance with the IEEE
802.3af standard. IEEE 802.3af allows for two power options for Category 5 (Cat5) cables.
• The PoE module signature and control circuit provides the PoE compatibility signature and power
classication required by the Power Sourcing Equipment (PSE) before applying up to 15 W power to
the port.
• The high efciency AC/DC converter operates over a wide input voltage range and provides a
regulated low ripple and low noise output. The AC/DC converter also has built-in overload and
short-circuit output protection.
C.1 PoE compatibility
With non Power Sourcing Equipment (PSE)
When it is connected with non PSE, use the power adaptor to provide power to the camera.
With power adaptor
Connecting both a PSE and a power adaptor does not do any harm to the products. Disconnecting the
power adaptor while it is operating does not stop operation. The product continues to work without
rebooting.
C.2 Power classication
The PoE Power Class supported by the IP device is Class 0.
Class Usage Minimum Power Levels Output at the PSE Maximum Power Levels at the Powered Device
0 Default 15.4 W 0.44 to 12.95 W
