You can now know when someone "crosses the line."  This high-tech device creates an invisible infrared beam up to 60 feet long.  When the beam is crossed, a loud alarm or a pleasant chime will be emitted.  Can be used as an invisible playpen to alert you to your child or pet leaving a safe play area.  The alarm can also be used at night to scare off would-be intruders.  In the chime mode, retail stores and businesses can use it to announce customers or alert them when someone enters an area that is "off limits."  You can choose to have the chime sound only one time (when a customer enters a store for example) or the chime can sound continuously until you turn it off (when a customer enters an area that is "off limits" or at home when a child leaves a safe area for example.)  Distance can be set to high or low (maximum distance 60 feet).  In the chime mode, volume can be set to low, medium or high.  Two AC adapters are included.  Three "AAA" back-up batteries are not included.
