RCA vidéo isolateur surveillant l'anti-interférence vidéo

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

Product Overview:

Isolateur vidéo en boucle de masse, also known as ground loop audio video isolator, est principalement utilisé pour éliminer les interférences avec la vidéo CCTV (ou audio) signaux provoqués par la tension de la boucle de masse. 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.

Normalement, la tension de la couche de blindage est de 0 V. When the local circuit/ground loop phenomenon exists, le niveau fluctuera autour 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. Lorsque la distance de transmission du signal vidéo dépasse 100 mètres, it is easy to generate high ground loop voltage. Si la tension de la boucle de terre est trop élevée, 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. En même temps, 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.

Il est souvent utilisé dans les vidéos de surveillance, home audio, salles informatiques, recording rooms, Images : voiture en marche arrière, KTVs, barres, car audio, and other image interference caused by common interference, comme les rayures, bruit de flocon de neige, horizontal lines, gigue d'image, engrener, image tearing, and a series of common ground interference.
