If the thought of a break in causes you to lose sleep and you can't afford an expensive home security system you can get this affordable wireless home security system for a fraction of the cost of a monitored system. The MACE wireless home security system is easy to set up and operate. It has a home security alarm that is triggered by either the door/window sensor of the motion detector. While the home security alarm is sounding, a signal travels to the base unit which calls the first of 5 preprogrammed phone numbers. The person answering the call will hear a prerecorded alert message and given the choice of listening, broadcasting their own voice through the base unit or disarming the system. If no one answers or the system is not disarmed, it will call the second person and the list, and so on. Included with the MACE Wireless Home Security System is a base unit with AC adaptor, 1 Window/door sensor, 1 motion detector and a remote control with a panic feature for arming and disarming the system
