Special version of the coaxial transmission: the one-cable technique

For many years now, we have successfully offered compact camera systems in one-cable tech-

nique. For this purpose, only one cable is led to the camera and this is not an expensive sys-

tem cable in which many different individual leads are bundled as it is the case with systems

of our competitors.

The camera system which we offer is connected via one coaxial cable. With this method,

both the video signal and the power supply are simultaneously transmitted via the coaxial

cable. The signals are separated by a special power supply adapter which is supplied

respectively.

Different camera series use this technology, e.g. the TVCCD-160S and the TVCCD-190 series.

As an adapter for retrofitting coaxial cables, we offer the SCU-100 which is able to addi-

tionally transmit an audio signal.

RG-58U 200m

RG-59U 350m

RG-6U 500 m

The number of cables to be laid is reduced due to the one-cable technique. This saves

material and labour costs, too. However, this is not the only advantage. Greater cable lengths

can be achieved by using active modules in the power supply adapters as required by the sys-

tem. Depending on the applied type of cable, the connection cable to the power supply

adapter may have a length of up to 500 m.

Transmission via two-wire cable

The transmission of signals via a two-wire cable offers many advantages.

• Crossing great distances, with active systems up to 1,500 m (colour signal)

• Cable material available at a favourable price, Cat. 5 UTP cable is usually sufficient

• Multiple utilisation of one cable, up to 4 signals via one Cat. 5 cable

• Less interference due to balanced signal transmission

Each signal is transmitted via one twisted pair of wires of the cable. This is one of the advan-

tages, because with the CAT-5100UTP cable, for example, there are 4 pairs of wires avail-

able which means that 4 signals can simultaneously be transmitted. To transmit e.g. 4 camera

signals from a warehouse to an office, it is no longer necessary to lay 4 video cables; one

Cat. 5 cable is sufficient. Even though two additional VB-400V transmission units are required

now, the total effort is less than with individual cables.

An additional advantage is the greater cable length to be used. With passive two-wire trans-

mitters, the max. possible length for colour signals is 400 m and the max. length for B/W sig-

nals is 600 m. With active single distances even a length of 1,500 or 2,400 m is possible.

In addition to the transmission of video signals, with special transmitters it is also possible to

transmit audio signals up to 1,000 m or to transmit VGA signals, mouse signals or keyboard

signals of a PC or digital hard disk recorder up to 100 m.
