The HumBloc® ground loop Isolator cures interference on CCTV images at a great price!
Earth or ground loop problems are a common problem faced at some time or another by CCTV installers with classic symptoms of the rolling humbar or the tearing picture and it can be time consuming to get to the root problem, let alone find a solution to cure it. A ground loop occurs when there is more than one "ground" or "earth" between two pieces of equipment. Because the two pieces of equipment have multiple ground paths, loops (circuits) are formed in which current can flow. Want to learn more about ground loop? Check out Tip 159 from our online Tech Tips.
Whilst using a good quality power supply should help prevent ground loop from happening, in complicated systems where a range of equipment is used it is not always easy to eradicate. A HumBloc® simply terminates any ground loop currents and blocks the interference. Simply fit the HumBloc® at the DVR or monitor end for a clear image.
