Description

*-Design Durability Highly Durable and Heat-Resistant Housing Cover and Chassis The housing cover 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&#**9;s energy blocked by heavy rain , dust storm , snow orfog *-High Grade Aspherical Lens The high grade lens creates more sharply defined and precise infrared beams compared to ordinary Fresnel lenses **-Twin Sychorized 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 LCDVoltage Displayer, it indicates the alignment level *****(Automatic Gain Control)Circuit The ***** continually monitors forgradual changes in the signal&#**9;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 judgment and removes interference validly to avoid evaded alarm
