Isn't an RF Modulator just used to convert AV to Coax and vice versa?
I'm not sure how this relates to being able change the channel on the TV and have it view a different camera?
Seeing as the TV is not within line of sight to the DVR, so cannot change the channel directly on the DVR.
Basically i want to be able to press "channel 1" on the TV, and view "camera 1", press "channel 2" and view "camera 2" etc...
And also have it split to multiple TV's if possible, so you could be viewing camera 1 on a TV in 1 room and camera 2 on a TV in another room. etc...
Is it not possible to have each camera broadcast on a different frequency down the same coax cable?
