The Audio Out port
can be used to connect
a stereo, speakers,
headphones or other
external sound device.
The Audio In ports can be used
to connect audio devices to the
DVR. Obviously, your microphone
probably won’t look like that one
- they’re often built into cameras.
An external hard drive
with an eSATA port can
be connected to the
eSATA port on the DVR.
The front USB port also supports USB solid-
state storage, such as flash drives.
The PTZ port (RS485)
can be used to connect
compatible PTZ devices,
such as this Swann PTZ
dome.
