We hired The Monitoring Center to install our alarm system after we heard an ad on the 1130 am radio. The technician (Adam) arrived on time and provided a professional installation. He installed the specified order items, plus a few items we ordered extra. He was knowledgeable and answered all my questions. He placed the sensors so the pet movement will not affect it. After few days I got also a quality assurance phone call from TMC, and I appreciate they follow-up on the work done. So far the system work great and we look forward for a long collaboration.
