What is the availability of wireless glass break and wireless shock detectors?

The manufacturer of the WisDom system has developed wireless glassbreak/shock detectors, which are now available:

Acoustic: http://www.diycontrols.com/showproduct.aspx?productid=6213

Shock detectors are often favored over acoustic glass break detectors and we suggest that you look into using them instead.  Acoustic glass break detectors use acoustics (the sound of breaking glass), which can be muffled by blinds, shades, or heavy curtains.  Shock detectors are a more reliable method of letting you know if someone is trying to intrude through a window.  They can even let you know if someone has tried to break the window and failed!
