4G Alarm Caller is a series of devices designed to notify users of alarms or any other events using the most convenient media ─ 4G mobile telephone service. Taking advantage of wireless 4G message service, alarm messages will be directly sent to users’ mobile phone. Since SMS has the “store and forward” feature, messages can still reach the users at a later time even when their phones are turned off or out of the service range of the 4G network. This significantly increases the reliability of alarming compared to traditional voice notification.
Besides text short message, voice messages notification are also available in certain models. Voice message can be sent to either a mobile phone or a regular telephone.
