Connecting the DVR
Connecting Additional Devices
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
a USB-compatible interface
(USB 2.0 recommended)
can be connected to the
USB port of the DVR.
The 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.
