The NetMedia MM70 Micro-Modulator converts composite video and stereo audio to a monaural television signal.The selectable channel is viewed with a standard television (SDTV) tuner. Once modulated,the signal is no longer bound to a single monitor or TV; it 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.
