Safety Beam
You can know when someone " crosses the line".
This high tech device creates an invisible infrared beam. When the beam is
crossed a loud alarm or a pleasant chime sound will be emitted. Can be used as
an invisible playpen to alert you to your child or pet leaving a safe area.
The alarm can also be used at night to scare off would-be intruders. You can
choose to have the chime sound only one time or the chime can sound
continuously until you turn it off (when a child leaves a safe area for
example). Distance can be sent to high or low. In the chime mode, volume can
be set to low, medium, or high. Two AC adapters are included. Three AA back up
batteries are not included.
