18. Audio Setting
Other models (such as 405-D20X, 601-D25X, 601-D20X and 406-D20X) don’t
have built-in microphone. You need to add an external microphone to the
camera’s RCA interface to enable sound pick-up.The cameras require an
active microphone, meaning the microphone must be powered.Microphones
are not included in the camera package and must be purchased separately.
A. Installation: how to install the microphone by running only one power
cable?
PoE Solution
A special DC male port has been made
on the camera's end tail to power the
microphone. The microphone can
directly apply its DC female port to the
existing male port on the camera. In
this way, the Mic is actually powered
by "borrowing" a few watts supplied to
the camera.
Non-PoE Solution
A Y-shape slippter (not included with
the camera) is necessary in this case to
divide the DC power from the adapter
into two:
1) One power stream goes to the
camera;
2) The other power stream goes to the
microphone.
