The Room Alert 4E package includes a license for AVTECH's powerful Device ManageR application software, an advanced solution for the discovery, management, logging, graphing, advanced alerting and more of AVTECH's IT & Facilities Environment Monitoring hardware. It runs as a Windows Service and automatically discovers AVTECH's hardware units or Axis IP cameras across the network, allowing users to immediately be informed when environmental thresholds are passed. Device ManageR's web browser interface allows users to view and manage any or all units on their network, graph and log sensor data in real-time or over a specified date range, send out alerts if an issue or event arises, and much more. Plugins are optionally available for Windows/Linux shutdown, reboot and/or log off; dial out via GSM, text or voice modems; advanced reporting, and more. New "dashboard" capabilities allow users to create the interface they desire, for their unique needs.

A Super Bundle of plugins is also available and includes all bundles at a low price so all functionality is available. As new plugins are added to these bundles, they are included at no charge for immediate download. There is no annual service fee for AVTECH's software, download access, new versions and technical support if support is maintained on AVTECH's hardware monitors.

GoToMyDevices is AVTECH's new, state-of-the-art cloud monitoring service designed for new and existing Room Alert users. It provides the ability to easily monitor temperature and environmental conditions from anywhere, at anytime, via the web. Regardless of your web interface of choice, the look, function, and entire user experience is always the same.

Users can monitor, alert, log, graph, view, report, map, manage and protect their facilities with both ease and confidence.

Room Alert 4E can easily monitor environments such as phone or wiring closets, critical rack cabinets and larger computer rooms or data centers and more. Since Room Alert 4E is connected via Ethernet and does not require a host PC for operation, it can be located anywhere an Ethernet connection is available. Power over Ethernet (PoE) is possible with AVTECH's PoE Splitter (5V). Sensors can be run inside a rack cabinet, air vent, sub floor or other location. Room Alert 4E will help to protect valuable IT equipment 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 4E can also be easily used in non-technology environments like residential and commercial buildings, restaurants, warehouses, green houses and more. The possibilities for use are endless.
