A haunting 9-1-1 call demonstrates how imperative home security systems are to protecting your family from danger. Two young sisters hid under a bathroom sink and called police after hearing two men attempting to break into their home while the sisters were home alone. The police dispatcher warned the girls to remain quiet and stay on the line while police were on their way. Had these girls not had a cell phone nearby, this story could have ended tragically. Home security systems can call police at the first sign of danger.
