**-Design Durability Highly Durable and Heat-Resistant Housing Cover and Chassis The housing and chassis provide higher durability against shocks , high temperatures , and many other harsh environmental conditions **- Frost and Dew Protection An anti-frost and convex visor design is incorporated to protect detector from effect of frost and dew ****9.5% Beam Blocking Stability Stable operation is maintained with as much as *9.5% of the beam's energy blocked by heavy rain , dust storms, snoe or fog **-High Grade Aspherical Lens The high grade lens creates more sharply defined and precise infrared beams compared to ordinary Fresnel lenses **-Twin Synchronized Pulsed Beam Desisned for Great Stability 'And Gate ' dual beams require simultaneous interruption of both beams to trigger an activation . No activation is generated when a bird or falling leaves break just one beam **-Adjustable Beam Interruption Period The Beam Interruption Time ( the mount of time a beam must be broken for an alarm to occur ) can be adjused to fit any applicatin . For example , when protecting a wall or fence , a longer interruption time will catch intruders , but let jumping cats pass through without setting off an alarm **-Quick optical and voltage alignment to speed up positioning Conveniently placed view finder allows for easy alignment , even in some of the difficult mounting situations. In the receiver there is a LCD Voltage Displayer , it indicates the alignment level *****(Automatic Gain Control )Circuit The ***** continually monitors for gradual changes in the single's strengh caused by changing weather . It adjusts the sensitivity accordingly to maintained proper singal level for the current environmental conditions
