A VGA connector is provided so that you can use a standard, multi-sync computer
monitor as your main monitor. Use the cable supplied with your monitor to connect
it to the DVR.
NOTE
The VGA and Video Out (BNC) connectors may be connected to individual monitors for simultaneous
operation.
NOTE
Please note the technical specification for the VGA output in Section 3: Technical data.

Audio input/output connectors
Your DVR can record audio from up to four sources. Connect the audio sources to
Audio In 1, Audio In 2, Audio In 3 and Audio In 4 as needed using RCA jacks.
Connect Audio Out to your amplifier.
NOTE
It is the user's responsibility to determine if local laws and regulations permit recording audio.
NOTE
The DVR does not have amplified audio output, so you will need a speaker with an amplifier. The DVR
does not have a pre-amplifier for audio input, so the audio input should be from an amplified source,
not directly from a microphone.

GND (Ground) connectors. When the electrical switch is wired, the
threshold voltage for NC (Normally Closed) is above 2.4V and for NO
(Normally Open) is below 0.3 V and should be stable at least 0.5 seconds
to be detected. For further information please refer to the Configuration &
Operation Manual: Section Alarm-In screen.

Connect the ground side of the alarm input and/or alarm output to the
GND connector.
