Light Keeper™ Anti-Terrorism
Twist Lock Type Photocontrol

Printable version

A standard photocontrol can be triggered by an artificial light at night, fooling it into thinking it is daylight and turning off a streetlight or floodlight. The area is left in darkness and in danger.
  • A helicopter with a spotlight pursuing a terrorist on the ground can inadvertently turn off ground lights – giving the cover of darkness to the terrorist.
  • An extremist with a flashlight or laser pointer can disable a perimeter light long enough to gain entry and perform illegal activity.

The LIGHT KEEPER™ is the solution. The LIGHT KEEPER™ has a new, unique, multi-sensor design to protect against photocontrol deception, keeping secure areas well-lit. It replaces standard twist lock photocontrols.
