We researched many security companies before we chose Telsco. For the price they offer a great service. We had a problem with one of our old sensors that was installed 25 years ago by a different security company. We had false alarms because of this sensor. Telsco sent out a tech and he diagnosed and fixed the problem in a very short time. There was no additional charge for this. We have been very pleased with their service and really like the fact that they are a local company. They are very responsive and make it easy to deal with them no matter what the issue is.
