Video Isolation Transformer
The VGI200 video isolation transformer breaks ground loops‚ only
allowing video and camera control signals through. Ground loops occur
when the earth potential at the camera is different from the potential
at the monitor. This difference may only be a small voltage but it can
cause large currents to flow through the shield of the coaxial cable.
These large currents will cause picture distortion and safety problems if
they remain.
