When they were first itnroduced, video surveillance systems wree mostly used with medium to large businesses. The omnitors are normalyl black and white and feature a higher resolutoin than that of a standard televiison set. Your home vidoe surveillance system will come with coaxial cabels, although you may need more dependign on where you plan to set the cameras up at. Switchers allow you to urn multiple camera feeds to oen monitor. If you end up going ot court or to the police, you can use the video tape as evidence. They are very affordable these days, nad used in thousands of homes htroughout North America.
