Garage Door Opener Interference... from 5GHz device?

[Gumbeaux]

I know people hate when threads are brought back to life, but I am in a jam...I have been told by Liftmaster Garage Door openers that my only solution is to chose which item is more important for me to use....My security cameras or my garage doors. We have had a 4 unit security CCTV system for 5 years, which is also the age of our garage door openers, and just recently added four more cameras (two that are near the garage doors). If the two new cameras, that are next to the two garage doors are plugged in and active, the garage doors open from the wall button, the remote control, and the Homelink car button IF you are directly underneath the motor(i.e. in the garage)...However, the remote control and the Homelink car system will NOT work if you are 15 feet away in the driveway. The company that sold us the Liftmaster unit has stated he saw this same issue with a fire station in town, but they are still looking for a solution. Once you unplug the two cameras that are next to the garage doors, everything works normally again.
The camera installer (15+ years with a major company in town) moved the security camera wires from the two new cameras away from the garage door opener wires and behind our spray foam insulation and attached 19 magnetic ferrite cores/chokes, but the problem is still occurring. However, he did not install a ferrite core to the garage door wall button wires. Our installer was told by others in his industry that this situation between the camera and garage door openers interference was not possible and they have never heard of it. I would appreciate any information.

I Saw no where on this thread that the problem is sometimes as simple as using LED and flourescent curly light bulbs in the garage door opener. It is a known interference and garage door companies are very slow to fix it. Soon there will no longer be any old incandescent bulbs to purchase.
