Video balun makers improve surge, multiple signal handling

R&D also covers cable compensation and adaptable solutions.


  • Improved surge protection: Surge-resistant configurations are entering the mainstream. These boast protection from EMI, static electricity and lightning-induced transient current. Basic models can control current surges of up to 1,200V, and advanced versions 2,000 or 6,000V.
  • Multiple signal transmission: Products support signals aside from video for simplified wiring and installation. Many suppliers have added 12 or 24VDC power transmission or audio handling. Upscale variants can even carry control data for PTZ and speed dome cameras.
  • Cable compensation: The latest active types feature a cable compensation circuit, which can balance signal attenuation depending on the UTP cable material and transmission distance. These have multigroup preset solutions.
  • Flexible solutions: Manufacturers are introducing more such versions to enable interoperability between passive and active balun kinds. These also meet the performance and cost requirements of different surveillance setups.
  • Price projection: Quotes will decrease by about 5 percent in coming months.
