What have you bought -
I for twisted cable converters allow to connect the analog
cameras through the twisted pair cable instead of the traditional coaxial cable.

Video signal supported -
The cable twisted DSE converters support all types of
analog video signal CVBS is traditional in AHD high resolution.
What is the twisted cable -
The twisted pair cable consists of two cables
What is the twisted cable -
The twisted pair cable consists of two cables
finely braided copper
Between them.
It can be, depending on the type of cable, protected by a metal sheath (shielded cable) or not
(unshielded). Both types can be used for video signal transport.
The video signal travels on this kind of cables better than it does on coaxial cables but the
signal converters are required, also called BALUN, at the beginning and at the end of the line
that permit the transmission of the signal in a balanced way, ie on two paired cables.
The cable to be used -
The reference cable to be used is the computer cables type
The cable to be used -
The reference cable to be used is the computer cables type
CAT-5 or CAT-6 UTP NOT SHIELDED,
largely
used
in
realization of LAN networks.
Each cable of this type contains 4 twisted pairs as in FIG.
Remember that the two wires that you will use for the video transport must belong to the same
pair of wires so
that
are
twisted
between
their.
You can not use straps or pairs of paired cables and not intertwined with each other, because
the transmission does not work.
E 'can use other twisted cables, other than CAT5 but the flow performance may be degraded.
The advantages of the twisted cable -
The twisted pair cable is more subtle kind of
The advantages of the twisted cable -
The twisted pair cable is more subtle kind of
coaxial cable and therefore easier installation. E 'can use existing cables such as computer LAN
networks, or telephone lines as
the only prerogative that is sought to cable is that the conductors are wrapped with each other
and not parallel. A single CAT5 cable can carry alone up to 4 video signals, performing the
function of well-4 coaxial cables. The use of active converters can reach even 2 km
transmission distance, while the coaxial cable does not allow more than a few hundred meters.
RE-BNCRJ1
Passive video converter
RE-BNCRJ1
Passive video converter
The RE-BNCRJ1 Converter is the easiest product family. It is a passive model that does not
perform signal amplification.
Do you need 2 RE-BNCRJ1 modules one from each end of the twisted pair cable.
The same module is reversible and acts both as a receiver and a transmitter. To connect the
module is sufficient to connect the
BNC connector to the video device
(Camera, monitor, VCR, etc.) and the twisted pair to the two ter/-. Power supply is not
required. Be careful not to reverse the order of the cables on the two converters: + to + and - to

RE-BNCRJ1E
Passive video converter
RE-BNCRJ1E
Passive video converter
The RE-BNCRJ1E converter is the same as the previous model but with the addition of a video
surge protection.
Furthermore, this model presents some installation advantages as the BNC connector is
mounted on a cable and the terminal block is with quick coupling. The
operation and installation are similar to the previous model, it is also possible to also use
in coupling a RE-BNCRJ1 with a RE-BNCRJ1E to the two ends of the cable.
RE-BNCRJ1A
Passive audio video converter 12VDC
RE-BNCRJ1A
Passive audio video converter 12VDC
The RE-BNCRJ1A converter is a passive balun as RE BNCRJ1 but allows in addition to the
video transmission also to conduct the audio signal and 12VDC power supply for the camera.
The RE-BNCRJ1A converter is sold in pairs. The transmitter module must be connected to
video connector / audio / 12VDC
camera, the receiver module connects to the audio video inputs of the display device (monitor,
etc. DVR) and 12VDC power supply.
Between the two modules you connect a CAT5 cable to complete LAN networks RJ45
connectors. The crimping of the 4 pairs within the RJ-45 connector cables must be carried out
as for the rights of a LAN network (see figure).
