Annually, more property damage and loss is caused by environmental conditions such as water leakage, temperature extremes, humidity and power failure than by theft or fire. Which is why the EnviroAlert Wireless Environmental Monitor and Alert System is an investment in your greatest asset, your home. This base unit can monitor up to eight external sensors (4 wireless, 4 hardwired), sold separately, that measure the environment, power and electrical as well as water and leak detection.. Because you can use multiple wireless sensors, you can not only monitor remote areas of your home, but you can cut down on the cost and difficulty of running cables everywhere. Each sensor has a designated relay output which can be connected to other devices such as an alarm or dialer, each sold separately, so that you can be notified when a program limit has been surpassed. By linking this with any alarm system with remote notification, you can be informed in the event of an emergency, whether you are at home, at work or out of town.
