I was all set to choose a competitor when I moved into my new house, but got a recommendation to call Hawkeye. When I met with the no-pressure sales rep Chris, he explained my options and the costs. My home was already equipped with a number of sensors that he thought would work with my upgraded unit. He was right. My installer was prompt, courteous and professional. The touch-screen keypad and free downloadable security app are super cool and work great. No problems! I HIGHLY recommend Hawkeye!
