The NetMedia MM73S TriplePlay Stereo Modulator converts three composite video and stereo audio signals to three MTS Stereo television channels. The selectable channels are viewed with a standard television (SDTV) tuner. Once modulated, the signals are no longer bound to a single monitor or TV;they can be combined with antenna, cable, or satellite signals for distribution to multiple TV's throughout the location. This provides convenient viewing access to security cameras, DVR's, or other audio/video (A/V) sources such as DVD's and VCR's.
