Product overview：
Ground loop video isolator, also known as ground loop audio-Video isolator，It is mainly used to eliminate the short circuit caused by ground circuit voltageCCTVvideo（Or audio）Signal interference。Ground circuit/Ground loop interference is an electronic interference phenomenon，It is mainly caused by the different potential between the two ends of the video cable。Since the video cable selects different video signal reference ground potential，Thus causing AC current loop interference，It mainly appears on the shielding layer of video cable and the shell of video equipment。
under normal conditions，The voltage of the shielding layer is0V，Local loop/When the earth ring phenomenon exists，The level will be at0VFluctuation from left to right，More serious will lead to serious distortion and tear of the video signal with horizontal lines－Anilox－Snowflakes and other interference phenomena。When the video signal transmission distance exceeds100Meter case，It is easy to produce high grounding loop voltage，If the ground ring voltage is too high，It may even cause the equipment to burn down。
Single channel video ground loop isolation anti-jamming device,The device can calmly process input and output balanced audio or balanced video signals that need to be isolated，At the same time, a common mode interference filter is also integrated，Used to eliminate interference signals from transmission cables，The converted unbalanced signal can be directly connected with the unbalanced input of audio and video。
It is often used in surveillance video，Home video，computer room，Recording and broadcasting room，Vehicle reversing image，KTV，bar、Vehicle audio and video, etc. some image interference caused by common interference，Like stripes，Snowflake noise，Horizontal grain，Image dithering，Anilox，A series of common ground interference such as image tearing。
