EnviroWatchThe EnviroWatch is a great device for watching over your home when you can't.

Built-in low temperature and power failure sensors constantly monitor conditions in your home, and when needed, call into our 24 hour (link) SRS monitoring center to alert you or your neighbors.

Auxiliary inputs allow for additional sensors for high temperature, water or just about anything you can think of.

This simple and rugged device is made by Electro Industries in Monticello, Minnesota.
