DM-448R series is a viewfinder passive infrared detector which adopts digital
micro-processor with energy-pile up-logical process, random dynamic time
split technology. The PIR parts adopt precision column lens to upgrade
receiving effect, higher sensitivity but lower false alarm. With the buit in
battery and the exclusive electricity save up model, it can be used for a long
time of as twice as the other brand detectors.
