Your Room Alert Account provides the ability to easily monitor temperature and environmental conditions from anywhere, at anytime, via the web. Regardless of your web browser of choice, the look, function, and entire user experience is always the same. Use your account to view all connected sensor and monitor devices without the need to install software, configure an email server, or worry about network concerns. Users can monitor, alert, log, graph, view, report, map, manage and protect their facilities with both ease and confidence.Room Alert 3E can easily monitor environments such as phone or wiring closets, critical rack cabinets and other facilities of all types. Since Room Alert 3E is connected via Ethernet and does not require a host PC for operation, it can be located anywhere an Ethernet connection is available. This monitor is also Power over Ethernet (PoE) enabled which allows it to be placed anywhere PoE Ethernet is available (i.e. power source not required). Sensors can be run inside a rack cabinet, air vent, sub floor or other location. Room Alert 3E will help to protect valuable IT equipment or other property and minimize downtime if a disaster should occur. It can also be used to manage utility use by monitoring power consumption, allowing possibilities to reduce energy costs.Room Alert 3E can also be easily used in non-technology environments like residential and commercial buildings, restaurants, warehouses, green houses and much more. The possibilities for use are endless. It’s easy installation and use is the reason it is the highest volume selling Room Alert model available.
