Cameras
Conventional CCD or CMOS cameras are
connected to the DVR through the Audio/
Video/Network port (Item number 4 in
Picture 2-2) via the dongle included with
the system. The dongle shown in Picture
2-4 has eight Video In plugs (yellow) for
cameras and four audio input plugs (black).
The extra yellow and black plugs are Video
Out and Audio Out respectively.
The dongle also includes an female port
for an RJ45 connection. Also known as
an Ethernet cable, this is used to connect
your DVR to the Internet through a router or
modem.
PICTURE 2-4
The cameras and the dongle use BNC connectors.
Each lead is identified with its channel number.
The cameras will also need to be connected to a power supply – whether the power supply
included with the cameras or a power distribution panel. For best results, both the DVR and
the camera power supply(ies) should share the same electrical grounding.
For cable runs longer than 200 feet, cable runs within walls, or in areas where there is
electromagnetic interference, you should use high-quality shielded RG59 cable. RG6 cable
should be used for runs exceeding 800 feet and fiber optic cable should be used when
distances exceed 1,800 feet. In circumstances requiring cameras to be positioned over 200
feet from the DVR, the camera’s power supply should be located closer to the camera.
Video Output
This DVR supports video output to a TV or a monitor using the Video Out connector on the
dongle. The BNC Video Out lead on the dongle is labeled as such. For output through the
dongle, you will need to use a BNC to RCA adapter to connect to a TV with RCA inputs and a
signal converter box to connect to a VGA monitor or a television with VGA inputs.
Audio Input and Output
Audio input and output is also handled through the BNC dongle. Each channel, including the
output channel, is labeled on the lead itself. To receive audio signals, you must have a camera
with built-in microphone or a separate microphone located near the camera.
Normal output through the BNC audio out channel is usually over 200mv 1KΩ. It can directly
connect to an active sound box or amplified speaker.
