LST-4F is a ground loop Video separator designed to small CCTV installations, protect cameras, DVR’s and monitors from lightnings and electrostatic overvoltage.
Metal structures (poles, metal buildings) and multiple camera power supplies are causing distortions, which are eliminated by ground loop Video separator. Interferences of power line and potential discontinuity are eliminated by filter boosting high-frequencies.
The Ground loop Video separator protects cameras and DVR’s from potential differences, lightnings and power downs. Damage caused by potential differences and lightnings are different but results are the same (loss the warranty on cameras and DVR’s).

Main features:
- UTP converter for coaxial cable: It changes Video signal from twisted pair to coaxial cable.
- 3-stage surge protection: It protect cameras, DVR’s and other CCTV devices from lightnings, electrostatic overvoltages.
- High-frequency filter: A better quality of pictures on long cables, by compensation of attenuation high-frequency in UTP cable;
- BNC connector: Signal is transmitted by BNC connector.
- Bidirectional action: The signal is transmitted at any directions, therefore it can be installed on sending and receiving sides.
- Full compatibility: Panels of LST series are fully compatible with surge protections of LKT and SUG version, produced by Ewimar company.
To obtain full protection from surges is required connection ground.
