BNC CCTV Ground Loop Isolator Filter Keep video feeds clear by stopping ground loop interference in BNC CCTV systems. This inline ground loop isolator filter is designed for straightforward installation and reliable noise reduction in analog video setups. Key benefits Removes video hum and interference: Reduces common ground loop symptoms such as rolling bars, horizontal banding, and intermittent noise on video feeds. Easy to install: Inline BNC connections allow quick insertion into existing coax runs without system reconfiguration or power. Passive and maintenance : No power required and no adjustments needed after installation. Preserves signal integrity: Designed to maintain stable video transmission while isolating unwanted electrical noise. Compact and unobtrusive: Small footprint fits into camera runs and equipment racks without occupying significant space. How it solves problems Stops ground potential differences between cameras and recording equipment that create visible video artifacts. Isolates noisy or separately grounded devices so one noisy component does not degrade the entire surveillance feed. Works without changing camera placement, conduit, or power wiring, making it a fast corrective tool for image quality issues. Compatibility and function Intended for use with BNCterminated CCTV coax video connections commonly found in analog surveillance systems. Serves as an inline ground loop isolator and filter between camera and recorder, monitor, or video balun. Passive isolation prevents direct electrical continuity that creates ground loop currents while allowing the video signal to pass. Typical applications Between an analog CCTV camera and a DVR to remove horizontal banding or shimmer caused by grounding differences. In multicamera installations where cameras and recorders are powered from different distribution points and show intermittent noise. When extending video runs between buildings or across separate electrical systems to prevent groundinduced interference. Practical notes Install inline at the first convenient point between the camera and the receiving device. Compatible with standard BNC coax cable connections used in CCTV and analog video equipment. Ideal for technicians and installers needing a compact, nopower solution to electromagnetic and grounding noise issues. This ground loop isolator filter is a practical tool to restore clear video in BNC CCTV systems quickly and with minimal disruption to existing wiring.
