Ground loop video isolator, also known as ground loop audio-video isolator, is designed to eliminate interference in CCTV video or audio signals caused by ground loop voltage. Ground loop interference (GEI) occurs due to potential differences between the two ends of a video cable. This interference, caused by differing reference ground potentials in video signals, typically affects the shielding layer of the video cable and the equipment housing. Normally, the shielding layer voltage is 0V; however, when a ground loop exists, this level fluctuates around 0V, potentially causing severe video distortion, tearing, and interference such as horizontal bars, reticule patterns, or snowflake noise. Ground loop voltage is more likely to occur when video signal transmission exceeds 100 meters, and excessively high voltages may damage connected equipment.This single-channel video isolation device effectively isolates balanced input and output signals for audio or video applications. It includes an integrated common-mode interference filter that reduces noise from transmission cables. The converted signal can be directly connected to unbalanced audio or video input terminals. It is commonly used in surveillance systems, home video setups, computer rooms, recording studios, car reverse cameras, KTVs, bars, and automotive audio/video systems to reduce common interferences such as stripes, snowflake noise, horizontal grain, shaking, net-like patterns, tearing, and similar issues.Features: - Insertion loss less than 0.01dB - Interface: Male to female RCA with wire - Impedance: 75 ohms (input and output) - Compatible with NTSC, PAL, SECAM - Input level: 1V P-P, mixed: CCIR601 4:2:2 - Standard rate: 13.5MHz - Chromatic aberration: less than 1% across all patterns - Multi-element horizontal and vertical limited pulse response simulation - Bandwidth: 10 MHz to 20 MHz - Phase difference: less than 2 degrees - Gain difference: less than 2% - Mounting hole spacing: 73mm - Installation diameter: 3mm - Operating temperature: -25C to +70C - Relative humidity: 90% (non-condensing) - Structure: PVC shell - Size: 63mm x 36mm x 21mm - Color: As shown in image - Material: Plastic Package Contents: 1 x RCA Video Isolator Note: Lighting and display settings may cause slight color variations between the product image and the actual item.
