*-Design Durability Highly Durable and Heat- -Resistant Housing Cover and Chassis The housing cover and chassis provide higher durability against shocks, high temperature , and many other harsh environmental conditions. *-Frost and Dew Protection An anti-frost anf 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% oe the beam's energy blocked by heavy rain , dust storms , snow or fog *-High Grade Aspherical Lens The high grade lens creates more sharply efined and precise infrared beam compared to ordianry Fresnel lenses *-Twin synchronized Pulsed Beam Designed 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 adjusted to fit any application . 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 most 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 signal's strength caused by changing weather . It adjusts the sensitivity accordingly to maintain proper signal level for the current environmental conditions *-Digital vague artificial identification The frequency modulation of 4 frequency ranges adopts artificial intelligent vague identification and removes the interference validly to avoid evaded alarm
