I recently moved into a new townhouse that had an older existing alarm system. I Called Knightwatch Alarms and they sent their sales representative, Adam, same day. Adam was very courteous and friendly. Suggested a couple of upgrades and monitoring options. They had my system up and running within a couple of days. The technician, Merrick, was very knowledgeable, efficient and professional. He made sure I understood the operation of my alarm system before he left. Highly recommend this company.
