Room Alert 3E Wi-Fi is one of AVTECH's advanced hardware solution!

Room Alert 3E Wi-Fi is one of AVTECH's hardware solutions for "IT & Facilities Environment Monitoring, Alerting & More". It is designed specifically to assist with computer room temperature and environment monitoring in multiple locations simultaneously. Room Alert 3E Wi-Fi allows alert notifications via email, email-to-SMS, SNMP and more to devices like computers, mobile phones and mobile devices. Room Alert 3E Wi-Fi offers an easy to use web browser interface for settings changes and viewing real-time temperature and sensor status from anywhere. Mount the Room Alert 3E Wi-Fi in a server rack with the 1U 19" rack mount kit (assembled) or use without the rack mount in other environments where monitoring physical conditions is desired.

By attaching external sensors or a Light Tower Adapter & Relay, the Room Alert 3E Wi-Fi is the perfect host for specific and targeted monitoring with a focus on keeping costs contained. Room Alert 3E Wi-Fi allows alert notifications via email, email-to-SMS, SNMP and more to devices like computers, mobile phones and mobile devices. Room Alert 3E Wi-Fi offers an easy to use web browser interface for settings changes and viewing real-time temperature and other environment sensor status from anywhere you can always use a Room Alert 3E Wi-Fi!

It Includes ALL of the following:

  • The Room Alert 3E Wi-Fi package allows real-time temperature and environment monitoring, logging, one click data export, advanced alerting, Fahrenheit/Celsius, high/low watermarks, temperature values in alerts, custom alert text and more.
  • Easy Ethernet ‘Plug and Play' setup for remote temperature and environment monitoring from anywhere.
  • Includes built-in Digital Temperature Sensor.

Easy Monitoring

Room Alert 3E 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 3E Wi-Fi 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 3E Wi-Fi 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.
