GENERAL INFORMATION
Coaxial cable
The most common wiring for CCTV system is coaxial cable as shown here on the
left. The most popular coaxial is called RG59 and it carries video signals up to a few hundred meters.
Twisted pair cable
Twisted pair cables can be used in CCTV wiring instead of coaxial cables.
They are now very popular because of 2 important advantages: longer wiring range
(using
active transmitters) and
possibility to carry more than one camera over a single cable.
In order to use twisted pair cable for
CCTV applications two converters are required: one near
the camera (transmitter) and one at the other end of the cable (receiver).
Since these converter will balance-unbalance the signal they are also called BALUN.
Suitable twisted cable for DSE balun
The cable recommended
for use with DSE converters is the classic CAT-5 UTP non shielded network cable with contains 4 twisted pairs.
Up to 4 cameras can be run off a single cable.
It is also possible to use different cables, shielded or unshielded, and in
different materials, the only condition being that the conductors are
twisted into pairs. The use of alternative cables may cause a significant
reduction of the transmission range.
For more details on twisted pair cabling see the
Tutorial.
CVBS and
AHD video signal
DSE balun are suitable
for all analog video signals. They can be use for traditional composite
CVBS video as well as for latest generation AHD/CVI/TVI high resolution video
up to 5MP.
PASSIVE BALUNS
RE-BNCRJ1C
Passive converter
- Video only -
200 m. range
This passive converter is a video balun, ideal to send
video signal over twisted pair.. It's size is
just slightly bigger than a standard BNC connector and it does not require an external power supply.
At one end, this balun
has a BNC connector to connect to the CCTV device (camera or DVR). On the other side it has 2 screw terminals to connect one of the four
twisted pairs in the CAT5 cable.
Two converters are needed for each camera at each end of
the twisted pair cable. The device is reversible and is able to work as a
transmitter, when placed near the camera and as a receiver when closed to
the DVR.
The maximum length of cable
is 200 meters for transmitting standard analog CVBS or AHD/CVI/TVI
2MP
video signal.
Unlike cheaper similar balun on the market, this comes
with the BNC at the end of a short video cable that is convenient in several
installation scenarios. In addition, this model come with a clip mounting
system that allows you to link several baluns in a raw.
2 pcs. each camera are required.
