The Strobe Security System is a complete, do it yourself, wireless security system for home or business. It provides the same security and peace of mind found in professionally installed security systems but at a fraction of the cost. The system includes a motion detector, external siren, and two window/ glass break sensors. These window/ glass break sensors also have magnetic contacts that can be used to protect a door or window. In addition to an alarm, the motion sensor has a chime which can be used as a customer announcer for a business or to let a homeowner know when someone enters. The system is turned off and on with two included remotes. A panic alarm with lanyard is included and makes a great safety device for the elderly. The complete system includes 1 motion detector with alarm/ chime and flashing light, 2 remote controls, 2 glass break sensors and/or magnetic contacts, 1 external siren with alarm, 1 panic remote with neck cord, 2 alarm system warning decals, and adjustable mounting brackets and screws for the motion detector and external siren. Total system requires four 9 volt batteries and eight "AA" batteries that are not included.
