TriWatcher SIR10S


Newly developed Triwatcher method realizes high precision outdoor vigilance by discriminating/eliminating false alarm factors.

  • Selectable from 2 kinds of coverage patterns
    * Wide angle
    With wide angle, the unit is installed at a high place (2.0 - 3.0m), which allows multipurpose application. In addition, installing at a high place prevents vandalism.
    * Pet alley
    With pet alley, the unit does not detect movements of objects that are lower than the height installed. It is ideal for residences that keep big pets in the garden.
  • Unwanted external-light-proof performance
    By adopting a special visible-light cut filter, the unit considerably blocks external lights such as sunlight or car headlights, etc.
  • Equipped with newly designed spherical Fresnel lens
    Adopting spherical Fresnel lens has made an improvement on the unit's non-detect performance of small objects such as small animals, etc.
    Also, use of polyethylene for its material effectively prevents things from sticking on its surface, such as snow, frost, or even bird or insect droppings, thus enabling to maintain its high precision performance.
  • Horizontal direction adjustment
    The detection area can be adjusted without a additional bracket.
    It allow to set the precise detection area.

Selection Tips

Newly-developed TriWatcher method realizes high-precision outdoor surveillance by discriminating and eliminating false alarm factors. As it presents no concern about interference between transmitter and receiver unlike beam detectors or microwave detectors, many units can be installed in the proximity of one another and can even face each other. With the use of optional Pole Mount Kit (PMK1), the unit can be installed where there is no wall to mount on.
