"We've had Bay Alarm since we opened our store in 2012. They have consistently given excellent customer service. Their personnel are responsive, knowledgeable and unfailingly courteous. It's been a pleasure doing business with them and when it came time to move the store's location, they made transferring service a breeze. I can't recommend Bay Alarm highly enough."
