  • When we decided to have an alarm installed, we looked around for a reliable company to install a reliable alarm.Gavin Anthony of One-Tec Security was recommended by a friend who was pleased with the product and the service. We decided to give One-Tec a call and were delighted with the outcome. The job was done on time, no mess, no fuss with everything explained slowly for us oldies. Nothing was too much trouble, even moving the power point at a later date for me at no charge. I am confident to recommend Gavin Anthony and his company for your alarm installation.
  • After moving into our new home, we engaged OneTec to change over the existing alarm system to upgrade the security. Gavin was able to design a solution to meet our particular needs, including accommodating our pet and being able to alarm the house differently during the day when we are out and at night when we go to bed. Since then, Gavin has always been extremely helpful, prompt and cou rteous in being available on the phone or in person to resolve any technical problems or modifications requested. It is always a pleasure to deal with Gavin and I’m sure the One Tec business has been built on good customer experiences like ours.
  • I have known Gavin for about 6 years and he has been very professional and has been very helpful in all alarm and telecommunications needs that we had needed. Gavin's work is very neat and charge is very reasonable and he well versed with all the new technology available to have the work done. We would highly recommend Gavin for any work
  • We were very happy with your service at the time our alarm was installed in 2015 and are still happy with your continued phone service. Whenever we have issues we leave you a message and you are prompt to return our call and guide us to resolve the alarm issue over the phone. You are very professional in what you do and have a
    great personality.
