We had moved into our new houses and wanted an alarm. Jim cane for a consultation. He offeredo me two choices, one for if we want to use it when we were at home or just when we were gone. Since I'm home alone often we chose the first one. The instillation was easy and went smoothly. They key pad and app are very easy to use. The company even called to check up to see if we had any questions few days later! I would highly recommend them.
