You can know when someone " crosses the line".
This high tech device creates an invisible infrared beam up to 60 ft. long. 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. In the chime mode, retail stores in businesses can use it to announce customers are alert them when someone enters an area that is "off limits".
Features:
- 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 sent to high or low- maximum distance 60 ft. In the chime mode, volume can be set to low, medium, or high.
- Two AC adapters are included.
