DELTA D-SEP/HD aislador de bucle de masa de vídeo para AHD/HD-CVI/HD-TVI/CVBS, BNC, 75 ohmios, 4K

Unlike active video baluns or powered extenders, the DELTA D-SEP/HD is a passive inline ground loop isolator that requires no external power, making it an instant fix for interference in existing CCTV installations. It supports all major HD-over-Coax formats—AHD, HD-CVI, HD-TVI—as well as legacy CVBS, ensuring compatibility with both modern and older surveillance equipment. With a high isolation rating of over 60 dB and an insertion loss below 0.5 dB, it removes hum, rolling bars, and image distortion without degrading the video signal, even at resolutions up to 8MP (4K).

Highlights

• Supports AHD, HD-CVI, HD-TVI, and CVBS video standards
• Passive design—no external power required
• High ground loop isolation: >60 dB
• Low insertion loss: <0.5 dB
• Wide frequency response: 0–60 MHz
• BNC male to BNC female connectors, 75 Ohm impedance
• Compact ABS plastic housing for inline installation

In daily use

Install the D-SEP/HD directly in the video line between camera and DVR. Its BNC male-to-female design allows quick insertion without additional cables. The isolator effectively breaks ground loops caused by potential differences between equipment, removing horizontal rolling bars, flickering, or image distortion. Because it is passive, there is no need for a power outlet, making it ideal for retrofitting existing systems or for installations where power access is limited.
