You need to protect the equipment in your data center, computer room, or equipment room from the damaging effects of high temperature and high humidity.
The best way to protect sensitive electronics is to constantly monitor the temperature and/or humidity in your data center, computer room, or server room and be notified immediately about an air conditioning system or power failure.

The Computer Room Guard will give you immediate notification with a telephone alert call or with our Data Capture software running on a PC you will also receive alarm emails and text messages. The early warning you receive will allow you to take corrective action before the servers melt down, bringing the enterprise to a halt.

The Computer Room Guard will call up to eight phone numbers or pagers to notify key personnel of a problem with any computer room, server room, or equipment room. Call anytime and hear the temperature and humidity and power status in a data center, computer room, server room, or equipment room.

Computer/software independent telephone alert calls, made by devices like the Computer Room Guard, are a must-have for any mission critical monitoring application.

To receive email and text messages our free Data Capture software must be running on a PC or server. Data Capture sends out the emails.

For additional protection, water sensors, door sensors, or any sensor with a dry contact output can be connected to the Computer Room Guard. Get notified if there is a water leak or a door is left open.

The Computer Room Guard can be used as a simple single room temperature alarm, a multiple room temperature alarm, a simple humidity alarm, a multiple room humidity alarm, or any combination of sensors to fulfill your requirements for an environmental alarm.
