The WJ-HD300A DVR Series has more features and higher hard drive capacities. The Series is available in 9 and 16 channel configurations and both have a 250 GB base hard drive unit. With optional expansion units, overall storage capacity is up to 7.5 Terabytes (16 channel unit only).
The "A" Series allows camera setup over the network and offers 120 images per second in SIF mode. Up to four system controllers can be used in cascade mode. Each controller can control and view individual camera groups (1-16, 17-32, 33-48, 49-64). The new copy feature eliminates a programming step by automatically assigning the start time of the copy function as either the record stop time or record list selection point. Individual cameras can be programmed for the greatest number of images per second without any restrictions by the number of image programmed by other modes.
