The TempDefender G2 is a small RTU designed to keep an eye on all the environmental levels that affect your server rooms, phone closets, data centers, and any other equipment sites.

You can use the 8 discrete alarms on the back panel to monitor dry contacts, such as motion sensors, UPS, smoke detectors, flood sensors, AC and room entry. You'll also have dense analog coverage with support for up to 32 D-Wire sensors and 8 analog channels.

With the built-in web interface, you can log on to your TempDefender RTU from anywhere on the network to edit your threshold settings and view the current status of the room. Do you want to know the current room temperature? Do want to know the last time someone entered the facility? With the TempDefender you can get all this information right from your network PC.

Don't wait until the day your AC unit fails and your facility overheats - start protecting your gear today. This 1RU device is able to alert you of changing conditions 24 hours a day, 7 days a week, either via text messages and email or through your SNMP manager.

The TempDefender G2 is the best cost-effective way to proactively monitor your mission-critical networking equipment.
