Home security is going wireless. Alertme.com has unveiled a ZigBee-based system that lets consumers install home security systems without figuring out where to run wires.
The direct alert system notifies people via text message or e-mail about problems at home. Beyond traditional burglar and fire alarms, AlertMe can send messages when smoke or carbon monoxide alarms go off.
A range of sensors include door and window sensors, motion sensors and alarm detectors that listen for existing smoke or carbon monoxide alarms. These sensors are linked by Ember Corp.’s ZigBee network chips and wireless mesh networking software.
