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.
An external hard drive with a USB-compatible 
interface (USB 2.0 recommended) can be 
connected to the front USB port of the DVR.
The front USB port also supports USB solid-
state storage, such as ash drives.
The PTZ port (RS485) 
can be used to connect 
compatible PTZ devices, 
such as this Swann PTZ 
dome.
