Advanced Environmental Monitoring Systems utilize an array or sensors to monitor critical sever room environmental and security conditions. When an environmental sensor goes out of range of a configurable threshold or a security sensor is triggered, the system will notify you via email, alarm beacon, front panel LED indicators, web page notification, network management (SNMP) software or a SMS message (via a USB 3G modem). These rack mount and wall mount environmental monitoring systems provide Web-based remote surveillance of environmental conditions and security. A wide range of environmental sensors, intrusion detection sensors and alarms can be attached.
