My Grandmother had a camera as channel 69 on her Comcast service. After the direct TV guys left, she no longer can see the camera. I know the technology to "modulate" the camera signal is different with Direct TV than Comcast. Please note due to her age, asking her to go to different input on the TV is not an option. I called around and was told that there is no such thing as modulate the camera into Direct TV. Is this true? If yes, what would be another option? Also, the dog chewed up her Direct TV RF remote. Any place to obtain one without having Direct TV coming back? I am pretty technical regarding running wire.... Thanks you guys for all the help.
