LKTO-4 is system designed to protect CCTV instalations from lightnings, electrostatic overvoltages and vandalism. Device in form of standalone housing.

LKTO series have included models LKO and LKT models in one unit, so it’s possible to use twisted pair or coaxial cable in each channel. You can choose which one will be connected by switching jumpers on PCB (Coaxial / UTP). It’s a perfect solution for installations with different
.
 
Built in power distribution cameras provides 16 independent power outputs for cameras with protecting against short cicuits and lightning. Device is equiooed with optical signaling power of each channel and audible indication of fault on any of them
 
 

 

Features:

  • Simple connection of coaxial and UTP cables: Device has low-loss screw terminals that doesn’t require the BNC connectors for coaxial cables.
  • Universal conection: Panel is designed to connect both coaxial and UTP cable by using appropriate terminals and put on jumpers in correct position. Video signal from coaxial cable is transmited direct to BNC connector, but signal from UTP cable is changed from 110Ohm to 75 Ohm standard by build in Video balun;
  • High-frequency filter: A better quality of pictures on long UTP cables, by compensation of attenuation high-frequency;
  • 3-stage surge protection: It protect cameras, DVR’s and other CCTV devices from lightnings, electrostatic overvoltages.
  • Two-way operation: Each Video channel can work as transmitter or receiver.
  • Work without power: It’s a passive decive that can work without power
  • Cable Organizer: Properly constructed casing and high quality BNC connectors creates Professional CCTV cable organizer, providing aesthetics of installation;
