The Hikvision DS-2CD2T66G2-4I is a 6MP outdoor AcuSense gen 2 bullet camera. Empowered by deep learning algorithms, Hikvision's AcuSense technology can distinguish people and vehicles from other moving objects, such as falling leaves or small animals. While originally created with the purpose of preventing false alarms, AcuSense technology offers users several other key benefits such as advanced analytics, active deterrence and timely alerts. The most paramount feature with the AcuSense gen 2 cameras is the analytic alert which will generate alarm events that are searchable when reviewing recorded footage for specific incidents. This saves many man hours of wasted time reviewing irrelevant video trying to identify an event, saving the end customer time and money.
