Data networks should be installed right the first time.  Saving hundreds now, could cost you thousands later.  Call CRSA Technologies and we'll provide you a site survey and a plan for your new building. 


We can add to any existing data network.  We pride our selves on neat and labeled cabling installations.

If your network is problematic because of poor installation in the past, call Kingdom. Often, we can fix the "messes" and get you back on track to minimal time.


Lower standard parts are available and can usually win a low bid.  We've chosen to stick with the quality name brands.  While some off brands can save money, they don't have the reputation, reliability or track record of Leviton or Panduit.  

This is a 25 year investment, not something we want to redo in 5-7 years.
