An additional speaker may be installed to alert more than one area in the property and an optional solar charger may be installed with the sensor for even more convenience. Sample applications include storefront entrances, houses, driveways, and much more.

This latest product has a sensor range of up to 22ft (7m) and a wireless rangeof up to 328ft (100m), and can be used for monitoring a driveway or used as an entrance indicator. There is no requirement for any wiring between the speaker and the sensor and when tripped, the sensor wirelessly transmits to any programmed speaker.

The sensor has been designed into a weatherproof housing for outdoor use and the speaker makes a chiming sound or an alarm sound if the beam is interrupted. The speaker volume is adjustabl and when in alarm mode, the sounding time is also adjustable from 1~30 seconds.
