 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.
Passive and active
converters
DSE range includes passive and active baluns. Active baluns gives longer transmission range but need DC power supply.
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-BNCRJ1
Passive converter - Video only
200 m. range

The passive converter RE-BNCRJ1 is the cheapest video balun. It's size is just little bigger than a standard BNC connector and  it does not require an external power supply.
At one end, RE-BNCRJ1 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 located near the camera and as a receiver when placed to the monitor.
The maximum length of cable is 200 meters for transmitting both standard analog or AHD video signal.

RE-BNCRJ1C
Passive converter - Video only - 200 m. range

This passive converter is the cheapest video balun. 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 located near the camera and as a receiver when closed to the monitor.
The maximum length of cable is 200 meters for transmitting both standard analog or AHD/CVI/TVI video signal.
Same as previous model but with the BNC connector crimped on a short 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.
As for the previous model 2 pcs. each camera are required.

RE-BNCRJ1E
Passive converter - Video only + Protection
200 m. range

Same as previous model but including surge suppressor. In addition, the terminal board has plug-in connectors that do not require screwdriver.
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 m range

Unlike all passive converters above, the RE-BNCRJ2L, is an active balun, 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 both standard analog or AHD video signals.
The product includes one transmitter and one receiver. Both need 12VDC power supply (RE-AL4S adaptor to be ordered separately).
The transmitter unit includes a switch for setting the boost level according to the real cable length. The receiver comes with brightness and contrast adjustment.
