Delilnik tv1000 « Nazaj

TV-1000 is used as an extra security device in CCTV systems and protects CCTV equipment from the following:

• lightening discharge,
• voltage differences ad strokes,
• electric currents in video signal cables.

The device eliminates signal disturbances that take place with transmissions over a few hundred meter distances. It is equipped with gain control ranging + 5 dB to -5 dB.

One of the problems that can be encountered during video signal transmission over distances of a few hundred meters is atmospheric lightening discharge. Even if lightening does not directly strike the installation, the electromagnetic field that has been induced by it may cause a severe damage to an expensive VCR or other equipment connected to the network.

Another problem is the difference in voltage between various devices. This phenomenon may be observed during insertion of the plug into a TV set or plugging a long computer cable. The difference in voltage may be so high that the person who is plugging the TV or computer may get an electric shock. Both of these problems can be solved through installation of the separator.
