4-channel video separator, surge protection, LSO-4F

4-channel galvanic ground loop separator for CCTV solutions, 3-stage surge protector, lightning protection for video recorders, LSO-4F, LSO4F, LSO4-F, LSO-4
LSO-4F is device designed to small CCTV installations, protecting cameras, DVR’s and monitors from lightnings, electrostatic overvoltages.

Ground loop separator effectively eliminates distortions in Video, which are resulting from potential differences. They occur in situations, where cameras are installed on metal structures (poles, metal buildings) and too in case of  power supply of individual cameras from random sources. Additional filter eliminates interference arising from page of power supply and spikes of potential.

Ground loop separator protects cameras and DVRs from damages which are a results of sudden spikes of potential difference, which are a result of lightning and sudden exclusions of power supply. Symptoms of damage in this case are different than during the surges or lightnings but the results are the same, loss of guarantee on installed cameras or DVRs.


3-stage surge protection -  It protect cameras, DVR’s and other CCTV devices  from  lightnings, electrostatic overvoltages and use a stun guns. 3-stage of surge suppression to level of 4 kV and pulse power supply to 10000A , efficiently boil down it to safety level for CCTV devices.

Precision BNC connectors – Signal transmission is done by using precision BNC connectors, which are performed by CNC method.

Bidirectional action – The signal is transmitted at any directions, allowing to expand the installation options on the transmission or reception.

Full compatibility – Panels of LKO series are fully compatible with surge protections of LSO and SUG version, produced by Ewimar company.


To obtain full protection form surges is required connection ground.
