Expert Security Systems Integration for New England We were founded almost 30 years ago by the same two owners who lead us today. Our local office will know you and learn your needs. Your security issues will not be handled by a call center rep. One Source will help assess your risks, needs and possible security weaknesses before we design your system. We are an advisor and will offer preventative advice, so you can avoid many potential problems altogether. We customize each system to suit the end-user’s specific needs. We care too much to send sub-contractors to your home or business. Our highly-skilled technicians and salespeople are our own and are trained and screened by us.
