I am a local small business owner for the last 14 years. TSI re-wired my original alarm system and have been monitoring my business for over three years.
I had an excellent experience with the work that was done during the rewire. The technician John that did the rewire was patient and thorough and made sure everything was done correctly and to my specifications. He and the sales rep David took the time to make sure I understood how to use the new software for the alarm and the exit entry system.
The monitoring has been going smoothly and I have had no problems with the service. In the past I had to leave Alarmco because of repeated issues with tripped alarm notifications not being relayed to me correctly. I have not had any issues with TSI notifications.
I also really appreciate that TSI includes in the monitoring contract to send an officer in response to tripped alarms a few times per year (I think it's 4 times) at no additional cost. Compared to Alarmco where their was always an additional charge.
