While digital video is the way to go today, analog video still has a strong place in the market. The signals high vulnerability along with the limited life span of its storage media, renders it technologically obsolete. Nevertheless a CCTV technician should still be able to cope with analog installation issues and problems. This week we had a chance to play around with various analog video enhancement devices. They can easily be inserted in the video chain line providing a minimum to excessive image manipulation, depending on sources quality and desired result.
