Ground Loop ISOLATOR AND Hi Frequency Interference Blocker

Ground loops in the video systems can have following effects:

Hum Barsp - sometimes caused by light dimmers
RF Interference - a ground loop acting as an AM radio antenna
Cross-Talk - Ground loops can cause one signal to interfere with another
       

 

Solution:

  • Video Ground Loop Isolator could reduce "Ground Loop Interference" with CCTV signals and can easily install in a new or added to existing systems. It 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.
 
  • Video SYNC signal not balanced would cause picture bar rolling that happened on weak, strong differential signal into DVR. Or under long range cabling cause Impedance not Matching.. For Coaxial cabling, add CB001VH ( Coaxial BALUN) for extra interference rejection, twisted pair cabling, add TVB001
 
  • CHB001H special design for block the interference from electromagnetic wave, high voltage electricity, wireless station, elevators, heavy power on industry,...etc.
  • CHB001 Special design for block the interference from electromagnetic wave, high voltage electricity, wireless station, with Video Transformer Filter function

Why is there a "rolling" on the video image?

 

The reason to cause "rolling" image is from the power interference during transmission or the video transmission range is too big between 2 or multi channels to have the signal not balanced. For Coaxial cabling, you could add our new Product-CB001VH (Coaxial BALUN) for extra interference rejection. For Twisted Pair cable, you could use our TTP111VH (passive-short range type) or TTA111VH (Active-Long range type) to eliminate the interference.

 

Why is there a "Power Waving" interference on the video image?

 

Coaxial cabling either Twisted pair cabling may have "Power Waving" interferences, that most from High Frequency (such as radio) or Differences in ground potentials are typically caused by unbalanced power line loads. Then you could add our "Video Ground Loop Isolator" to eliminate the interference.

Generally, it is not easy to find out where this kind of interference from, so we would recommend use monitor to check each connecting point (between two wire connection), to find out where is the source of interference.

To block the interference from electromagnetic wave, high voltage electricity, wireless station, with Video Transformer Filter function. That you could use new model: CHB001.
