said by gizmojoe :I have a Leviton CATV distribution system that allowed me to inject security camera feeds into my cable signal path to be viewed on all the TVs in my house on channel 78. Using a Leviton Distribution Module with a notch filter, (CATV 75-80 suppressed in the incoming CATV feed) my camera signals were run through a sequencer and modulater, the output of which became an auxilary input to the distribtion module. I was quite happy with this setup until Comcast shut off all the analog channels recently, forcing us to use thier Pace and Motorola DTAs. Now, with DTAs connected inline to each TV, I believe that the DTAs or totally ignoring my analog signal so effectively Comcast's mandatory technology upgrade has c**ped all over my 3K perimeter Security video capability investment. Anyone have any idea of how to get these adapters to 'shift' my channel to channel 3 on the TVs? Is there any 'reserved' channel on the input of these that will allow this sort of injection on analog to be presented in the convertor's output that that channel is selected?
where are you located? If your system does not use channels above 120 or for digital services you could use analog 125 for the camera feeds. You would need a single channel notch filter also what channel do you have on your tv that displays the digital adapter screen in the 60-78 analog range? That would be the channel to use as cable companies have a channel in that range that they have to keep analog modulation on to balance the amps.
