As reliable as these systems are when it comes to protecting people’s homes, possessions, and families, they also can malfunction from time to time. False alarms are common in the home security system market. Many companies expect and train their employees to anticipate false alarm calls each day. While a false alarm may be embarrassing for the homeowner, you should still take comfort in knowing that home security companies will respond quickly each time the system’s alarms are triggered. Many companies also do not penalize customers for false alarms.
