SYSTEM POWER REQUIREMENTS AND SOURCES
UFODAP cameras and the Multi-Sensor Data Acquisition Unit (MSDAU) both use
Power over Ethernet (PoE) as a power source as a path for the data to a computer or
router. All six of the recommended cameras are PoE compatible meaning that a single
Ethernet cable provides the communication signals as well as power over otherwise
unused wire pairs. The single-port and 4-
port power “injectors” derive approximately
56VDC from the AC line and provide it to each port. The camera then converts this
voltage to lower voltages used internally.
The hardware required for that function is known as a PoE Injector or Injector/Switch.
This is a small device that is powered from a 115/230VAC, 50/60Hz source. An
Ethernet cable connects a computer or router to the Injector
’s uplink or LAN port and
another connects the Injector
’s PoE port to the camera or a MSDAU.
An injector may have more than one PoE port. Each port may be used to connect a
camera or MSDAU up to the limit of the injector’s total output power capacity. UFODAP
injectors have the following capabilities:
