I have 2 systems I use for security cams. They will interfer with 2 gig phones and wireless routers but you can change channels to avoid the
conflicts. I also went to 5 gig phones. Both of my receivers were overheating and the chroma signal would drop out, opening the case
stopped this. The range is not much, affected greatly by how many walls
you have to go through, 50' is a reliable range.
