With S-Video

The CTARM-2SV modulator allows consumers to watch what they want from any home TV without having to pay for extra VCRs, DVD players, cable boxes, satellite receivers, or surveillance monitors. The modulators also allow a consumer to introduce a new “video service” such as home security cameras to their existing cable system without additional wiring. In this example, a consumer could now monitor the security camera from a designated channel on any TV in the house at any time.

The CTARM-2SV residential digital frequency agile modulator allows for the insertion of multiple video and left and right audio signals from a variety of devices including satellite receivers, VCRs, DVD players, and security cameras on user selected TV channels. This modulator creates a separate TV channel for each video device, combines the new channels with cable or broadcast TV channels, and routes the output to all TVs in the home via existing cable outlets.

The CTARM-2SV features S-Video inputs to allow for a better quality video input from the audio video source.

The CTARM-2SV is housed in a low profile case with channel output selection buttons and LED channel display. Non-volatile memory is included to remember channel assignments in event of power failure.
