More info

Video ground loop isolator that reduces feedback interferences in CCTV video signals. Easily applicable in existing installations, where video signals are transmitted between different points with different potentials. Differences in potentials are typical in environments with unbalanced power lines.

Impedance
The impedance (Z) is a measure of opposition that a circuit to a current when a voltage is applied. The impedance extends the concept of resistance circuits alternating current (AC), and has both magnitude and phase, unlike resistance, which has only magnitude. When a circuit is powered with direct current (DC), there is no distinction between the impedance and resistance; the latter can be thought csa impedance with zero phase angle.
