The Synology DiskStation DS112 is a single bay Network Attached Storage (NAS) device in a sleek white design. It offers multiple interfaces including USB and Ethernet, providing flexible connectivity options for easy data storage and sharing. As part of the DiskStation product line from Synology, this model is reliable and efficient in managing and storing data for home or small office use. It was used in my business for the surveillance system. What you see is what you get. Thank you
