  • Perimeter Security were recommended to me by a close friend after a burglary at my home last month. As I didn’t know too much about home alarm’s, the technical manager advised me on the range of options available to me. Installation was within 2 weeks of my original phone-call, and am now comforted in knowing that my home is alarmed.

  • With construction theft on the increase, it is essential that we hire security systems for all of our sites at reasonable prices. We have been using Perimeter Security for the past 4 years and have found them to be invaluable to the operation of our business. I can highly recommend the team at Perimeter Security, they are very knowledgeable and are more than willing to adapt systems for our individual neds.
