The Ultimate in Protection DFIR** & Microwave!
The NEW M-2015 with DFIR**
With Microwave Doppler technology, multifrequency signals indicate motion in a monitored area. Now, Dual-Frequency InfraRed technology (DFIR**) brings this same multifrequency feature to infrared motion sensing. Together, they add up to M-TEC -- dual multifrequency technology. Only motion produces multifrequency signals. Other stimuli do not. Good-bye, false alarms!
