Lenel Systems International's GuardallVision standalone digital video recorders (DVRs) combine the benefits of high-quality video with the power and convenience of embedded real-time analytics, including object detection, loitering, object left behind, object crosses a region, smart motion detection and invalid camera. With capacity for up to 16 video channels, live recording at up to 30 frames per second, and as many as four terabytes of redundant onboard video storage, the units support easy monitoring and maintenance of multiple DVRs. A number of recording modes, such as continuous, event-driven, motion-detected, and scheduled, are fully supported and come standard in the DVR.
