Problem with garage door openers

I have been having problems with my garage door openers since I installed my security system.  I read online that radio waves can affect the working of garage door openers.  The openers will work one time and then two hours later they will not work.  I would think it would be just the one opener but I have two openers from different manufacturers and the problem is intermittent. So my thoughts are that it is some kind of waves that is causing the problem.  Garage door repair person could not find any problems.  Has anyone else had problems and if so how did you solve it.  Security system is the only that I have added recently that sends out signals and I had no problems before installing.  Any help would be appreciated.
