Description
Video horizontal & vertical SYNC signals not balanced would cause picture 'up-rolling' that happened on weak, strong differential signal into DVR, monitor or video image processing equipments.
Other case like under long range cabling cause 'Impedance not Matching'. The video transformer filter is designed with multi- stage high common mode noise and jamming rejection, video termination and video filtering circuits for most of high noise environment.
For Coaxial cabling transmission CCTV application, using UST140TF or UST180TF ( Coaxial BALUN) for extra interference rejection
