Sensaphone telephone alarm dialers monitor for power failures, low temperature and freezing, dry contact closures or any number of environmental sensors. When a problem occurs, the voice dialer will call one or more key staff members, owners or property managers. Sensaphone telephone monitoring systems are used for greenhouse operations, barn monitoring, livestock monitoring, residential and commercial monitoring systems. They can be used on their own or used with automation systems like Priva to provide an extension to the system.
