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.
