3~12 Watts
PoE Splitter
PoE Splitter split the PoE 52V DC over the Ethernet cable into 5/12V DC
power output. It frees the device deployment from restrictions due to power
outlet locations, which eliminate the costs for additional AC wiring and
reduces the installation time.
3~25 Watts
High Power PoE Splitter
High PoE Splitter split the PoE 56V DC over the Ethernet cable into 24/12V
DC power output. It frees the device deployment from restrictions due to
power outlet locations, which eliminate the costs for additional AC wiring
and reduces the installation time.
30 Watts
High Power Speed Dome
This state-of-the-art design is considerable to fit in various network
environments like traffic centers, shopping malls, railway stations,
warehouses, airports, and production facilities for the most demanding
outdoor surveillance applications- no need electrician to install AC sockets.
Since the NS3702 series per PoE port supports 56V DC PoE power output, please check and assure
the Powered Device’s (PD) acceptable DC power range is from 56V DC; otherwise, it will damage the
Powered Device (PD).
4.16.2 System Configuration
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN
infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power required
by PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a PSU capable of
supplying less power than the total potential power consumption of all the PoE ports in the system. In order to maintain the
majority of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal to the
system’s aggregated power consumption .The power management concept allows all ports to be active and activates additional
ports, as long as the aggregated power of the system is lower than the power level at which additional PDs cannot be
connected .When this value is exceeded, ports will be deactivated, according to user-defined priorities. The power budget is
managed according to the following user-definable parameters: maximum available power, ports priority, maximum allowable
power per port.
Reserved Power determined by
There are five modes for configuring how the ports/PDs may reserve power and when to shut down ports.
