High Performance Ground Loop Isolator – Video BNC
Model: VFGBNC
 
The video ground loop isolator reduces ground loop interference with CCTV signals. It can be installed easily to a new system or as an additional isolator in an existing system. The isolator is useful where a video signal is transmitted via cable between points with different ground potentials. Differences in ground potentials are typically caused by unbalanced power line loads.
 
Features:
  • BNC male to BNC female with mini cable – 9.45" / 240mm on both sides.
  • Built-in TVS (Transient Voltage Suppressors) for surge protection.
  • High Performance to eliminate ground loop problem.
  • Low video loss, Bandwidth: 20hz-11Mhz, +0/-3dB.
  • Passive; No power required.
  • Prevents video-signal distortion caused by video ground loops.
  • Eliminates picture tearing, cross talk, and rolling.
  • Prevents power cables laid by others interfering with the CCTV system.
  • It is useful where a video signal is transmitted via cable between points with different ground potentials.

OKINA USA Cabling Systems and Solutions provides an answer for all your cabling needs. Our complete line of baluns allows you to easily extend your current audio/video/data system up to 1200ft and even up to 8000 ft, with an active balun.

OKINA USA Baluns are perfectly suited for applications such as these:
CCTV Security Systems
CCTV Surveillance Systems
CCTV Cameras
Home Theatre
LCD/CRT Monitors
Televisions
VGA Monitors
DVD Players
PCs (Personal Computers)
Laptops/Notebooks
USB and PS/2 Devices
UTP (Unshielded Twisted Pair Cable)
BNC (Coaxial Cable)

How does a balun work?
Baluns are used to convert between "Balanced and Unbalanced" electrical signals.
Baluns work by transforming the original unbalanced (video/power/data/etc) signal to a balanced frequency used by a different cable, like CAT5 UTP. Not only does this reduce interference, but it also allows you to transmit a signal much longer than the original application would allow. Baluns are always utilized in pairs. One balun is needed to convert the original signal to a new frequency, and another balun is used at the other end to revert to the original frequency.

"Passive" Video Baluns do not require power, and can extend a signal up to 2000ft (B/W)
"Active" Video Baluns require power, but can extend a signal up to 8000ft (B/W)
