RF transmission demodulator DM-100S that enables the transmission of multiple (up to 60 channels) composite video and audio signals over a single coaxial cable!
The video and audio are converted to RF and transmitted via coaxial cable. The DM-100S is an RF transmission demodulator that restores the video and audio (mono) transmitted after modulation to composite video signals and audio signals (line level). By changing the frequency channel used for RF conversion for each video, multiple videos can be transmitted over a single coaxial cable in combination with the MD-500 (RF transmission modulator). The mechanism is the same as that of cable television. Using this method, it is possible to transmit video and audio equivalent to approximately 60 channels over a single coaxial cable for distances of up to 250 to 800 meters (when using 5C-2V). (This varies depending on the frequency.)

basic information
- The DM-100S demodulates signals sent via RF from the MD-500 (RF transmission modulator) into video and audio signals (mono). - By setting channels for each video, multiple videos can be transmitted over a single coaxial cable. - If multiple DM-100S units are set to the same channel, the same video can be extracted individually from each unit. - Power adapter sold separately (LTE12WS-S2 DC plug type). - Optional 19-inch rack mount panels are available for 3, 6, 9, or 12 units, making it convenient for storage in a 19-inch rack. * This product does not support AHD / HD-TVI / HDCVI video signals, etc.

Applications/Examples of results
●If you want to display composite images from surveillance cameras in multiple locations, you can split the video at a central location where all the camera feeds converge, convert it to RF, and transmit the signal over a single coaxial cable to another location. Even with a large number of feeds, such as 32 images, you can view all the footage in another location by simply running one coaxial cable. ●If there is cable television wiring in the building, you can use unused frequency channels to transmit camera footage and your own video and audio broadcasts. In addition to sending camera footage to the control room, you can distribute produced videos to each room. The video converted to RF can be displayed on CATV-compatible televisions and VCRs. ●This is effective in places like schools and shopping centers where the same footage needs to be displayed in multiple locations. The RF signal is wired through a single coaxial cable, split at each display location, and input into tuners to show the video. By setting all the tuners to the same channel, you can display the same footage on all monitors.
