All of Hikvision' s Turbo HD GT DVRs are now powered by Motion Detection 2.0, which detects human beings and vehicles through each analog channel to focus on real security threats. Users can quickly search video footage based on the appearances of persons or vehicles during a specific period of time. The DVRs with AcuSense technology are capable of video content analysis (VCA) designed to narrow down the monitoring scope in perimeter protection and face detection and comparison to provide more detailed results.
