This single-channel video isolator eliminates ground loop interference by electrically isolating input and output signal paths while integrating a common-mode interference filter. It suppresses AC-induced noise entering via cable shielding or equipment chassis — the root cause of horizontal stripes, snowflake noise, tearing, rolling distortion and image shaking in analog CCTV and AV systems. Designed for unbalanced RCA signal paths, it requires no external power and delivers transparent signal pass-through with minimal degradation. Ideal for long-distance CCTV video transmission (beyond 100 m), where ground potential differences between cameras and DVRs/NVRs commonly exceed safe thresholds. Also used in car reversing systems, home AV setups, computer rooms, recording studios, KTVs, bars and other environments prone to electromagnetic interference from lighting, HVAC, motors or shared power circuits.
