LST-8R is 8-channel passive UTP converter, integrated with ground loop separator as an RACK 19" patch panel. It is designed to change Video signal from UTP twisted pair to coaxial cable and protect CCTV devices from effects of surges and potential differences.
It includes inside several functional blocks, to help to do installations of cables to DVRs or matrix switchers. Are also available mixed version with LST series and power supply distributor.


UTP converter for coaxial cable – changes symmetric Video signal from impedance of twisted pair (100 Ohm) to signal of coaxial cable (75 Ohm).

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.

High-frequency filter - corrects the high-frequency, compensates attenuation in cables. As a result the Video quality as higher in areas of sharp edges and color quality as higher.

Ground loop separation – eliminates distorted of Video, which are resulting of alignment potential difference on Video cables. Protect device such as cameras and DVRs from damage as a result of ground loop surges. Amorphous core introduces negligible signal losses and harmonic distortion, which always appear in optical separators.

System of permanent mounting a cables – Specially constructed bracket with holes is used to permanent mounting the cables by clamp and protect from pulling, even by using large force.

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.

Easier installation in Rack cabinet - Suitably shaped holes simplifies installation for front of RACK cabinet. After applying LKT-MOUNT set the panel can be mounting on back of cabinet at 45 degrees, allowing to very comfortable laying cables in back of cabinet, where they are always available for installer and patch cord cables can be directly connected to CCTV devices.

Full compatibility – Panels of LST series are fully compatibility with surge protectors of LKT and SUG series, produced by Ewimar company.


To obtain full protection form surges is required connection ground.
