The SAT4D satellite-based monitoring system from Sensaphone delivers immediate alerts of changes in conditions at pumps, wells and storage facilities located in areas without a phone line, Ethernet connection or cellular service. It can monitor virtually any critical condition 24/7, including security and power status. When an alarm occurs, the system sends notification to up to eight telephone numbers and six email or text messages. It is self-powered and can operate for over three years on its replaceable battery. GPS technology pinpoints the location and status of equipment being monitored. Each unit is sealed in an enclosure to protect it from harsh conditions. 888/369-4781; www.sensaphone.com.
