SCS Security Stories

John & Faralee Cook, Homeowners

Mike Schuh at S.C.S. Security Systems Ltd. installed our alarm system in 1985 and we have been happy customers since that time. Over the years S.C.S. has updated our system to keep it current with todays technology as well as made timely necessary repairs as components have worn out. Many years ago the system detected a fire on the kitchen stove before our housekeeper was even aware of the problem. An immediate call from the monitoring company to the fire department kept damage and expenses to a minimum. We cannot say enough good things about S.C.S. Security Systems Ltd. and have relied on them for almost 30 years to keep our family home safe and sound.
