The LC-171 is unique motion detector utilizing dual passive infra-red elements and Microwave 

technology for use outdoors and in harsh environments.  

The LC-171 is designed for outdoor use in the most severe climatic conditions and may also 

accommodate pets. 

High reliability is achieved by combining both dual tech hardware with highly sophisticated 

software and an adaptive coverage area, greatly reducing the possibility of false alarms. 

The active elements are comprised of a dual element PIR

 

and advanced Microwave detector 

inside a stylish, rigid plastic body.  

This special optics combined with state of the art microwave Doppler sensor assures elimination 

of “false alarms” while maintaining high security standards for the detection of human intruders 

into the protected area. 

The detection sensitivity and range is controlled by a digital rotary switch allowing 16 calibration 

levels, so that the correct detection pattern will be set for every installation.  

The LC-171 is designed to protect large areas and can easily be installed on walls or poles in 

order to provide a solid area of protection while rejecting interference from birds and small 

animals due to the provided pet immunity optics.
