    I am a huge fan of the ring security system. The monthly cost is low and the customer service is outstanding! You set how many alarms you have in your home. No getting charged a arm and a leg for adding more equipment. Continue to add more and the monthly charge remains the same. This unit allows to have multiple key pads in the house.
