This is AVTECH Software's most advanced hardware solution for "Computer Room Environment Monitoring, Alerting & Automatic Corrective Action." It is specially created to aid with observing power, flood, computer room temperature, humidity and more in multiple locations. This can be done while using wireless technology to prevent running cables. Room Alert 26W's Wireless Sensor Hubs (WiSH) convey information through a protected, restricted protocol that is ZigBee compatible. This gives users the ability to monitor large numbers of sensors both indoors and out, up to 250' away.
