The DS-2CD2646G2-IZSU/SL is a varifocal outdoor, IP66 rated bullet camera which has an IR range of 60m. Hikvision's AcuSense Gen 2 range hits a milestone in area protection and perimeter security by combining existing features such as line crossing and perimeter detection with an enhanced deep learning algorithm. AcuSense can accurately distinguish people and vehicles from other moving objects which reduces the amount of false video motion alarms by up to 95 percent. Powered by Hikvision's Darkfighter technology, AcuSense Gen 2 can deliver clear cut images even in the lowest lighting conditions of 0.003 lux at F1.4 (4MP). AcuSense Gen 2 activations will generate alarm events which will be 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 time and money for the end customers. The inclusion of two-way audio allows customisable warnings to be played when an event takes place or automatically trigger the built-in alarm siren and strobe light.
