I currently have Comcast basic analog service coming into my home. I send this to my distribution amplifier via a low pass in-line transformer that basically only allows the channels below channel 103 or so to pass through. This is so I can "clean up" the bandwidth above channel 103 to modulate my CCTV security cameras onto and view security cameras just by going to those modulated channels, just like switching TV channels. I only use the tuners in the TV's because we dont have premium channels.
Now I am thinking of switching to Comcast digital service and getting some premium channels. I realize that I will need converter boxes for whatever sets I want premium channels. But I'd still like to be able to keep an analog signal alive throughout the house with my filter xformer and CCTV camera modulators. For the TV's where I just want to use the built in tuner.
Will I have any issues with modulating my 4 CCTV cameras to their current channels 124, 121, 118, and 115? Or must I rethink how I can use my modulated CCTV cameras in a digital Comcastic world? I do have2 runs of RG6 to every room only one of which is currently being used.
