We have recently installed Telsco as our home security system and it was a great experience right from the start. The Telsco technician was very friendly, thorough, and obviously great at his job. He was also super helpful in showing us how to use the app and he updated our doorbell system, which had not been working. I accidentally tripped the alarm one day and Telsco was very prompt in contacting me to ensure everything was alright. They were fast to contact and went through verification checks. Overall, I am extremely impressed; the technician was great and Telsco has been a very great and reliable security company.
