Atsumi Electric Co Ltd
TriWatcher Method
The newly developed TriWatcher method from Atsumi Electric Co., Ltd. realizes high precision outdoor vigilance by discriminating/eliminating false alarm factors. Choose from 2 kinds of coverage patterns: wide angle, where the unit is installed in a high place, or pet alley, where the unit does not detect movements of objects that are lower than the height installed. By adopting a special visible-light cut filter, the unit considerably blocks external lights such as sunlight, car headlights, etc. It is equipped with a newly-designed spherical Fresnel lens that improves the unit's non-detect performance of small objects such as small animals, etc.
