● ARI (Alarm Reset In)
An external signal to the Alarm Reset In can be used to
reset both the Alarm Out signal and the NVR’s internal
buzzer. Mechanical or electrical switches can be wired to
the ARI (Alarm Reset In) and GND (Ground) connectors.
The threshold voltage is below 0.3V and should be
stable at least 0.5 seconds to be detected. Connect the
wires to the ARI and GND connectors.

Audio Connection
Connect the audio device to the AUDIO IN port and
speakers with a built-in amplifier to the
AUDIO OUT
port. Use the
AUDIO OUT
port to listen to audio from
network cameras.
Use the AUDIO IN port to establish two-way
communication with cameras.
• This NVR does not feature a built-in audio amplifier
unit and therefore requires the user to purchase a
speaker system with a built-in amplifier separately.
It's possible to connect an amplified audio source to
the NVR, but microphones that do not have a built-
in amplifier will not function properly if connected
to the NVR directly. If this is the case, connect the
microphone to the NVR via a pre-amp.
• Check your local laws and regulations on making
audio recordings.
Power Cable Connection
Connect the power cable to this port. This NVR does not
feature a separate power on/off button and will turn on
the moment power is supplied.
• Organize the power cable so that it will not cause
people to trip over or become damaged from chairs,
cabinets, desks, and other objects in the vicinity. Do
not run the power cable underneath a rug or carpet.
• The power cable is grounded. Do not modify the
power plug even if your power outlet does not have
a ground contact.
• Do not connect multiple devices to a single power
outlet.
