Plug-and-play sensor integration

The AlertWerks ServSensor V4EL with 20 Dry-Contact Inputs enables you to integrate multiple types of environmental sensors into one seamless remote monitoring system that watches over your premises. Each ServSensor supports up to eight AlertWerks Intelligent Sensors. Sensors automatically configure and go on-line, ready to report any status change. Choose from a wide variety of sensors, including water, airflow, motion, and voltage. Additionally, the V4EL has 20 integral dry-contact inputs so you can also use third-party sensors.

Easy-to-use Web interface.

The ServSersor hub gathers and displays sensor data in an easy-to-use, Web-based user interface, automatically generating day, week, month, and year graphs for each sensor. The data can be downloaded for external processing or remotely polled and saved automatically to a PC.

Notification Wizard.

The Notification Wizard enables the hub to notify you of changes in sensor status in real-time. Configure each notification by choosing a sensor, selecting the alarm condition, and defining what to do when the alarm is triggered. You can choose to be notified in a variety of ways: audible alarm, SNMP trap, e-mail, text message to your phone, or fax.

For instance, you can have the system e-mail you if the temperature in your data center goes over 75° F and send you a text message if the temperature continues to climb and goes over 80° F.

You control the number of events.

To prevent false alarms, AlertWerks allows extensive filtering of events. You can limit events based on the time of day or the day of the week. You can also limit the number of alerts per hour so that you are not swamped with messages. This is especially important with a sensor like the motion detector where you may want to process an event only after hours.


You can have Linux® devices automatically send a shutdown message to your Linux or Windows® based servers - so if there is a power outage, for example, you can rest assured that your servers will be safely and automatically shut down before your UPS runs out.
