SMEA-1P  Single channel Professional
microphone interface for power over
Ethernet IP cameras

 

The SMEA-1P permits the connection
of any ETS PM1 professional series
microphone (or any other balanced
12/48v phantom powered or dynamic
professional microphone) to the
‘microphone input or ‘audio input of a
PoE IP camera without the need for an
additional power supply. The SMEA-1P
is placed in line with the camera’s
CAT5/6 cable run and borrows a small
amount of power from the PoE line to
power up the interface and microphone.

Supports
both modes A and B of IEEE802.3af.
