RM70
The RM70 Coax-Powered Single Channel Modulator converts composite video and stereo audio to a monaural
television signal. It is powered over the same coax cable that returns the video broadcast signal. It can even supply
remote power to 12VDC cameras for One Wire Video™ Installation.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 conve-
nient viewing access to security cameras, DVR's, or other audio/video (A/V) sources such as DVD's and VCR's.
