Point-to-Point Beams

Effective Perimeter Protection

Photoelectric dual beam sensors are a cost effective way of securing your property and being alerted of anyone entering your property's perimeter instantly.


Beams are ideal for securing:

  • Driveways
  • Gates
  • Sheds
  • Farms
  • Lifestyle properties
  • Utility areas
  • Yards

We have photoelectric beams in both wired and wireless models, with a variety of different ranges from 20 to 200 meters depending on your requirements.

The solar powered photoelectric dual beam sensors we use, are the most advanced wireless beam on the market.


  • Solar powered beams with a battery backup
  • Two synchronised beams for added reliability
  • Small discrete all-in-one self-contained unit
  • Activated by breaking both beams (less prone to false alarms from pets)
  • Does not require a heat source for activation
  • Able to be connected to an alarm system
  • Suitable for temporary or long-term protection
  • Up to 500m transmission range to receiver unit.

Our solar-powered wireless beams start from only $650+GST.  If you would like to know how perimeter protection could work for your property, please contact us.
