Video amplifiers are designed to help you extend the normal transmission distance of CCTV video over coaxial lines. This can be useful when you are settng up a security video system in a large room, or need to run lines down hallways, stairwells, or elevator and air vent shafts. Video converters change composite video to PC-compatible VGA signals for display on a VGA monitor. |
Video baluns balance impedance across unequal transmission cables. This situation occurs when you connect coaxial (coax) cable to CAT5 cable (UTP or STP). The impedance characteristics of CAT5 and coax wire differ, so a balun provides the necessary conversion and filtering. They can also help you extend your video cables further than if you were using coax straight from the CCTV security camera itself.

Sometimes you want to view security camera output on a regular television (not a composite monitor). Standard signal output from a CCTV security camera is composite video and is NOT viewable on a television screen (television requires an NTSC signal). A modulator corrects this situation and allows you to connect a CCTV camera to a regular television set (non-digital, non-hi-def).
