I frequently see camera and VMS favorites here and a few access control favorite topics here and there. Why not have a structured cabling manufacturer favorite?
For us for a long time it was 3M until they were sold to Corning and then we switched to CommScope.
No complaints from either brands other than I wish their product lines were as complete as Belden's or Panduit. Why don't we use these two? Price, lots of competition, and the CommScope reps are good friends of ours.
