GENERAL INFORMATION
 Coaxial cable
The most common way of wiring CCTV system is using coaxial cable as shown here on the left.
The most common type 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.
Twisted pair cables gives 2 important advantages: longer wiring range 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 positioned near
the camera (transmitter) and one at the other end of the cable (receiver).
Since these converter will balance-unbalance the signal they are commonly called BALUN.
What cable to use with DSE converters
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 mean less efficient
performance levels.
For more details on twisted pair cabling see the
Tutorial.
Passive and active
converters
DSE range includes passive and active baluns. Active baluns gives longer transmission range but need DC power supply.
PASSIVE BALUNS
RE-BNCRJ1
Passive converter - Video only
400/600 m. range
The passive converter RE-BNCRJ1 is the most practical to use with twisted
pair cable as it does not require an external power supply. At one end it
has a BNC connector to connect to the CCTV device (camera and monitor). 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 located near the camera and as a receiver when placed to
the monitor.
The maximum length of cable
is 600 meters for transmitting a B/W signal and 400 meters for a color
signal.
RE-BNCRJ1E
Passive converter - Video only
400/600 m. range
Same as previous model but including surge suppressor. This version is
recommend for cabling running outdoor.
In addition this balun comes with
BNC connector crimped on a short cable that is convenient in several
installation scenarios.
As for the previous model 2 pcs. each camera are
requested.
RE-BNCRJ1A
Passive converter - Video+Audio+12VDC
100 m. range
The passive converter RE-BNCRJ1A is similar to the previous model RE-BNCRJ1 but besides video signal, can manage audio and 12VDC power as well.
This converter requires one CAT5 UTP cable per camera.
Unlike the previous models, the RE-BNCRJ1A is sold in pairs because transmitter and receivers are not the same.
The transmitter (camera side) has 1 BNC video input, 1 RCA audio input and 1 DC plug for the camera.
The receiver (monitor side) has 1 BNC video output, 1 RCA audio output and 1 DC jack to connect the camera power adaptor. UTP cable connects the 2 modules using the classic
RJ45 LAN plug .
Cable lenght cannot exceed 100 m. when 12VDC power transmission is used.
ACTIVE BALUNS
RE-BNCRJ2L
Active converter – Video only
2400/3000 m range
Unlike all passive converters above, the RE-BNCRJ2L, is an active converter, which means that is able to amplify the signal and extend the transmission range.
The max. distance between the camera and the monitor is up to 2400 m for color signals and up to 3000 m for B/W.
The product includes one transmitter and one receiver. Both need 12VDC power supply (RE-AL4S adaptor to be ordered separately).
Each module include a switch for setting the boost level according to the real cable
length.
RE-BNCRJ2
Active converter – Video+Audio+RS485 BUS
1500/2400 m range
The active converter RE-BNCRJ2 is similar to the previous model RE-BNCRJ2L but besides video signal, can manage audio and one RS485 BUS for controlling speed dome cameras.
This converter requires one CAT5 UTP cable per camera.
Both transmitter and
receiver require a 12VDC power supply. (2 pcs. 220VAC adaptor included)
The maximum lenght of cabling is 1500 m for color cameras and 2400 m for B/W.
