Everyone knows the ADT symbol – especially burglars – and that’s why you should choose an ADT monitored home security system for your home or business. For more than 130 years, ADT has been the leader in home security and continues to lead the industry with technologically advanced products and programs. Studies show that a home that is not protected by an electronic security system is three times more likely to be targeted by thieves. And thieves know that ADT is the #1 company in the business for comprehensive home protection. An ADT sign outside your home may help keep you safe inside.
