I am not sure what is setting off my home security , which has started going off at various times during the night. It always occurs at night, and there are never any indications of a break-in or other questionable behavior. The neighbors are looking out their windows as the loud siren wakes us all up. Has anyone else in the community experienced this? What was the reason for those odd alarm trips during the night? After inspecting the motion sensors and door/window connections, it appears that everything is operating as it should. I would really appreciate any information on what could be triggering my alarm system unnecessarily; I am having trouble sleeping!
