VIDEO INPUTS/OUTPUTS INSTALLATION
Cameras and CCTV monitors must use copper-core or copper-braid 75 Ohm video cable (e.g. RG-59, RG-6, RG-11) with
BNC connectors.
To avoid impedance mismatching and undesired loss/reflections, 50 Ohm coax cable (e.g. RG-58), or 75 ohm foil shield
antenna cable and other types of coaxial cable should not be used.
All connected video sources must provide a 1 Vpp NTSC or PAL standard video signal.
When converting other transmission types (twisted pair, fiber optics, radio) for the video inputs, be sure to verify accurate
receiver calibration and signal levels.
ATTENTION:
In order for the system to auto-detect the appropriate video format (NTSC or PAL), make sure that there is a
video signal on video input 1 (Channel 1) upon power-up.

AUDIO INSTALLATION
This DVR provides 4 line level audio inputs and 1 line level audio output.
ATTENTION:
The direct connection of a non-amplified microphone is not supported (a microphone amplifier is required).
The audio output requires an amplifier to drive a speaker or headphones.
The audio installation must be done with audio coax cable and RCA plugs.
AUDIO RECORDING FUNCTIONALITY:
Audio recording is activated / deactivated in the Camera Menu for each camera respectively. Please check and always
comply with local laws and regulations when using audio recording.
The audio channel is recorded with the video channel and is independent of the image recording rate. Audio recording is
standard and do not require any further setup.

ALARM CONTACTS INSTALLATION
The alarm inputs can be configured to trigger recording or to adjust recording rates.
Alarm inputs can also trigger the related
camera’s feed to be displayed on the monitor, or trigger a buzzer, an e-mail or a network alarm. The alarm output relay can
be enabled if required. Alarm-input reactions can be controlled according to a flexible schedule.
