TSV-1000P - VIDEO SEPARATOR
SV-1000P is used as an extra security device in CCTV systems and protects CCTV equipment from the following:
- lightning discharge,
- voltage differences and strokes,
- electric currents in video signal cables.
The device eliminates signal disturbances that take place with transmissions over several hundred meters distances.

The Fig.1 shows the SV-1000P video separator connecting diagram example. It allows to eliminate signal disturbances due to difference in voltage between camera ground and monitor ground. The voltage results from this difference can adds up to useful signal voltage. It makes low frequency disturbances (e.g. slowly vertical moving black fields). To full protect all devices connected to the line against lightning discharges the Fig.2 connecting diagram is recommended:
