1. The infrared detector uses the professional detector and infrared digital dealing IC.
2. High shoot frequency uses the latest SAW technique, cooperate with the mature peripheral circuit, for which making the infrared detector has the features of: Good sensitivity, low rate of false alarm, steady high shoot frequency, great shoot rate.
