Product Overview

The Humbug from Tecton is a ground loop isolator. This device is used in-line between a CCTV camera and a monitor or recorder. It eliminates humbars (caused by bad grounding), picture tearing, crosstalk and rolling caused by ground loops or power interference introduced into the coaxial video cable. It can be used to improve video signals at existing or new installations. Humbug requires no power supply and passes video and camera control signals in both directions. It was developed due to the lack of high quality ground loop isolation transformers. Humbug is made up of the latest ferrite materials using high quality magnetic engineering to achieve high bandwidth throughput.
