Monitoreo de aislador de video RCA Video Anti interferencia

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

Product Overview:

Aislador de vídeo de bucle de tierra, also known as ground loop audio video isolator, Se utiliza principalmente para eliminar interferencias en el vídeo CCTV. (o audio) señales causadas por el voltaje del circuito de tierra. 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, el voltaje de la capa protectora es 0V. When the local circuit/ground loop phenomenon exists, el nivel fluctuará alrededor 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. Cuando la distancia de transmisión de la señal de vídeo excede 100 metros, it is easy to generate high ground loop voltage. Si el voltaje del circuito de tierra es demasiado alto, 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. Al mismo tiempo, 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.

Se utiliza a menudo en vídeos de vigilancia., home audio, salas de ordenadores, recording rooms, Imágenes de auto marcha atrás, KTVs, verja, car audio, and other image interference caused by common interference, como rayas, ruido de copo de nieve, horizontal lines, fluctuación de la imagen, malla, image tearing, and a series of common ground interference.
