Isolador de vídeo RCA que monitora anti-interferência de vídeo

RCA Video Isolator Monitoring Video Anti interference AV Video Filter Eliminating Strong Electric Horizontal Snowflake Noise Suppressor

Product Overview:

Isolador de vídeo de loop de terra, also known as ground loop audio video isolator, é usado principalmente para eliminar interferência em vídeo CCTV (ou áudio) sinais causados ​​pela tensão do loop de terra. Ground loop/ground loop interference is an electronic interference phenomenon mainly caused by the different potential between the two terminals of a video cable. Due to the selection of different video signal reference ground potentials for video cables, the interference caused by AC current circuit mainly occurs in the shielding layer of video cables and the shell of video equipment.

Normalmente, a tensão da camada de blindagem é 0V. When the local circuit/ground loop phenomenon exists, o nível irá flutuar em torno de 0V, and more seriously, it will cause serious distortion and tearing of the video signal, accompanied by interference phenomena such as horizontal lines, mesh lines, and snowflakes. Quando a distância de transmissão do sinal de vídeo excede 100 metros, it is easy to generate high ground loop voltage. Se a tensão do circuito de terra estiver muito alta, it may even cause the equipment to be burned.

Single channel video ground circuit isolation anti-interference device, which can handle balanced audio or balanced video signals that need to be isolated from the input and output calmly. Ao mesmo tempo, it also integrates a common mode interference filter internally to eliminate interference signals from the transmission cable. The converted non balanced signals can be directly connected to the unbalanced input end of audio and video.

É frequentemente usado em vídeos de vigilância, home audio, salas de informática, recording rooms, imagens de carro invertendo, KTVs, bares, car audio, and other image interference caused by common interference, como listras, barulho de floco de neve, horizontal lines, tremulação de imagem, malha, image tearing, and a series of common ground interference.
