Aritech motion sensors have the most advanced and sophisticated mirror optics in the security industry. This unique optical mirror technology is a step and gliding focus which creates a continuous curtain resulting in a sensor that never loses track of the object. To increase detection coverage, the 1000 series sensors use the 3Brid orthogonal curtain design. This is a horizontal mirror structure that creates curtains with vertical orientation which detect IR. This orthogonal invention is the key in adding curtains to the mirror without sacrificing signal strength nor increasing the size of the sensor.
