Rca Video Isolator Monitoring Video Interference Av Video Filter Eliminates Strong Current Horizont f74 Ground loop video isolator, also known as ground loop audio-video isolator, is mainly used to eliminate interference to CCTV video (or audio) signals caused by ground loop voltage. Ground loop/ground loop interference (GEI) is an electronic interference phenomenon caused by the different potential between the two ends of a video cable.The interference of ac current loop caused by different video signal reference ground potential is mainly found in the shielding layer of the video cable and the shell of the video equipment.Under normal circumstances, the voltage of the shielding layer is 0V, and when the local loop/ground loop phenomenon exists, the level will fluctuate around 0V, and more seriously, the video signal will be seriously distorted and torn, accompanied by interference phenomena such as horizontal stria-reticule-snowflake.When the transmission distance of video signal is more than 100 , it is easy to generate high ground loop voltage. If the ground loop voltage is too high, the equipment may even be burned down.Single-channel video isolated circuit anti-interference device, the device can calmly deal with the balance of input and output need isolation balance audio or video signals, and internal also integrated common-mode interference filter, filter is used to eliminate the interference signals from transmission cables, non equilibrium after conversion signal can be directly connected to the unbalanced input terminal of the audio and video.It is often used in surveillance video, home video, computer room, video recording room, car reversing , KTV, bar, car video and audio and other interference caused by common interference, such as stripe, snowflake noise, horizontal grain, shake, net grain, tear and a series of common interference.Features: Device insertion loss Less than 0.01dB is minimalInterface: Male and female head with wire type RCAImpedance: 75 ohms (input-output)Styles: , NTSC, SECAMInput level: 1VP-P, mixed: CCIR601 4:2:2Standard rate: 13.5MHzChromatic aberration: less than 1% of all patternsResize: Multi-element horizontal and vertical limited pulse responsesSimulation processBandwidth: 10 MHZ to 20 MHZPhase difference: less than 2 degreesGain difference: less than 2%Spacing of mounting holes: 73mmInstallation diameter: 3mmWorking temperature: -25 to +70CelsiusRelative humidity :90%(non-condensation)Structure: VNB-GliB00MF /, VNB-Gli00MF / PVC shellSize: 63 mm x 36 mm x 21 mmcolor:As shownMaterial:plasticPackage Contents:1 x RCA Video Isolator MonitoringOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
